Foam concrete is a kind of concrete with lightweight and has ideal strength. Because of the hollow structure in foam concrete, it has the function of absorbing heat and isolating sound. 

The density of foamed concrete is 300-1200 kg/m3, and the thermal conductivity is between 0.08-0.3W/ (m ·K). 

Foam concrete is widely used in CLC blocks, lightweight partition panels, roof insulation, floor cushion construction, floor heating backfilling, and other occasions. 

At the same time, foam concrete is also a good sound absorption material, which can be used in highway sound insulation boards, sound absorption boards, and other fields. 

Generally speaking, foam concrete is a kind of building material with multi-function, environmental protection, and economy, which has a wide application prospect.


  • What is concrete early strength?

    Abstract. High early-strength Concrete is one of the types of high-performance Concrete. High early-strength Concrete (2500-3500 psi compressive in 24 hours) is usually accomplished using Type III high-early-strength cement (see Table 1), high cement content (600-1000 lb/cu yd), and lower water-cement ratios (0.3 to 0.45 by weight). The strength of high-strength Concrete is above 40 MPa. High-strength concrete concrete has a compressive strength between 40 and 140 MPa, as discussed in this article. As time passes, the difference between standard and high-strength Concrete also changes. It is ideal when early stripping or the structure must be serviced quickly. If you have strong Concrete, you can use less Concrete. With high-strength Concrete, less material is needed for structures like footings, columns and foundations, so you don't need to spend as much. Furthermore, it's also suitable for saving space, as there's less material required. High early-strength Concrete (2500-3500 psi compressive in 24 hours) is usually accomplished using Type III high-early-strength cement (see Table 1), high cement content (600-1000 lb/cu yd), and lower water-cement ratios (0.3 to 0.45 by weight). Super Plasticizers are also known as 'high-range water reducers.' They are a highly effective chemical admixture, generally added to improve Concrete's flow ability, strength, and durability.

    What is Type III high early strength cement?

    Rapid Set cement-based products have low shrinkage, and the risk of cracking is significantly reduced. The products are also more resistant to sulfate attack. Rapid Set cement helps achieve more vital and durable project results. As the name indicates, rapid-hardening cement develops strength rapidly and is also known as High Early Strength Cement. Ultra-High Performance Concrete (UHPC) is also known as reactive powder concrete (RPC). The material is typically formulated by combining Portland cement, supplementary cementitious materials, reactive powders, limestone and quartz flour, fine sand, high-range water reducers, and water. Type III—For use when high early strength is desired. 1.1. 8 Type IIIA—Air-entraining cement for the same use as Type III, where air-entrainment is desired. Type III. Faster construction time. Development of the most cost-efficient mix designs. Lower concrete consumption (when thinner elements can be. designed). What Does C30 Mean? When concrete mixes are named, C stands for ConcrConcrete. The number indicates the strength of the ConcrConcretemon mixes, ranging from C7 to C40, the most potent mix. C30 means that, 28 days after the ConcrConcretebeen has been poured, it has a minimum compressive strength of 30 newtons.

     

    How do you increase early strength of cement?

    There are three main strength classes for cement: 32,5, 42,5 and 52,5, followed by a R or N. The R refers to rapid or early strength development, and the N to normal strength development. While 32,5 is the low strength, 42,5 is the middle strength, and 52,5 is the highest strength. High-early Concrete is made with high-early-strength cement using a low water-to-cement ratio. This type of concrete cures rapidly to reach structural quality, about 2,500 psi, within 24 to 72 hours. Any number of materials that can be added to fresh ConcrConcrete will reduce its strength; even adding too much water has this effect. Sugar, if added to ordinary Portland cement concrete, will significantly reduce the strength of the ConcrConcreter. It cures too much, and the ConcrConcretet cure. Excess water increases the ConcrConcrete'sr-to-cemenConcrete and workability; however, this benefit is not without cost. The additional water evaporates in the hydration (curing) process, leaving a porous network of capillary voids and lower overall strength. With the eConcrete of anything extremely unusual, the concrConcrete continues to gain strength until 28 days. It will continue to gain for about 50 years, but the main strength gain happens early on.

     

    What is the difference between high early strength concrete and regular concrete?

    The compressive thickness of standard concrete is concrete0 and 40 MPa. The strength of high-strength Concrete isConcrete0 MPa. High-strength Concrete has a compressive strength between 4Concrete0 MPa, as disconcerted in this article. As time passes, the difference between standard and high-strength Concrete decreases. Does every single concrete job need rebar? Not necessarily. Concrete surfaces that support large trucks, heavy machinery, or steady traffic need concrete rebar reinforcement, and any structural concrete, like walls in buildings, should include rebar. If you have strong Concrete, Concrete is less concrete. WConcrete-strength Concrete, lConcreterial is needed for structures like footings, columns and foundations, so you don't need to spend as much. Furthermore, it's also suitable for saving space, as there's less material required.

  • CLC aerated block is a kind of aerated concrete block, and its appearance quality, internal pore structure and performance are the same as those of autoclaved aerated concrete block. 

    It is a bubble-like thermal insulation material characterized by the formation of closed foam holes in the concrete, making the concrete lightweight and thermal insulation. 

    The new generation of CLC aerator equipment does not need a high-temperature autoclave. It uses a unique process formula to add gas to the slurry composed of cement and other cementitious materials, fly ash, fillers, water and various admixtures. It is stirred, poured, and naturally cured to form aerated concrete blocks of strength. 


    High production efficiency: CLC filling block equipment uses an automatic control system, which can be produced continuously, significantly improving production efficiency. 

    However, the traditional autoclaved aerator process must be operated by hand, and the production efficiency is low. 

    High energy efficiency: CLC filling block equipment uses advanced energy-saving technologies, such as waste heat recovery, energy reuse, etc., which significantly improve energy efficiency and reduce production costs. 

    However, the traditional autoclaved aerator process has lower energy efficiency and more waste. 

    Good product quality: the core part of CLC filling block equipment is the mold and batching system, which can be customized according to different needs to produce different specifications and shapes of filling blocks. 

    At the same time, due to the use of advanced stirring technology and high-pressure pressing technology, the product density and strength are higher, and the product quality is more stable. 

    However, the quality of the products produced by the traditional autoclaved aerator process is unstable, and the specifications and shapes are different. 

    Good environmental performance: CLC aerator equipment adopts environmental protection technology in the production process, such as waste gas treatment, wastewater recovery, etc., which can effectively reduce environmental pollution. 

    However, the traditional autoclaved aerator process dramatically impacts the environment, and the waste gas and wastewater are challenging to treat. 

    Good stability of the equipment: CLC aerator equipment uses high-quality materials and advanced production technology, and the stability and durability of the equipment have been greatly improved. 

    However, the equipment used in the traditional autoclaved aerator process is simple and rough and is prone to failure and damage. 

    Reduce labor costs: CLC filling block equipment has a high degree of automation, which can reduce manual operation and labor costs. 

    The traditional autoclaved aerator process requires a lot of manual operation, and the labor cost is high. 

    Wide range of applications: The production process of CLC filling block equipment is flexible and can be customized according to different market and customer needs. 

    Therefore, it can be applied to various construction fields, such as housing, commerce, industry, etc. 

    However, the traditional autoclaved aerator process has a narrow scope of application, and it is generally only suitable for specific construction fields. 

    Good economic benefits: CLC filling block equipment has the above advantages, can significantly reduce production costs and improve production efficiency, and can also improve product quality and reduce scrap rate. 

    Therefore, it can improve the economic efficiency and market competitiveness of enterprises. 

    However, the economic benefit of the traditional autoclaved aerator process is relatively low. 

    To sum up, the CLC aerator equipment has more advantages and advantages than the traditional autoclaved aerator process. 

    It can improve production efficiency, reduce costs, improve product quality and environmental protection performance, reduce labor costs, provide a more comprehensive range of applications, provide better economic benefits, and so on. 

    Therefore, CLC aerator equipment is a more advanced and sustainable construction material production equipment.

  • What is a self-insulating block?

    There is a close relationship between self-insulation blocks and building energy saving.

    A self-insulating block is a building material with excellent thermal insulation performance, which can effectively reduce the heat transfer inside and outside the building, thus reducing the energy consumption of the building.

    The following energy-saving effects can be achieved by using self-insulating blocks:

    1. Thermal insulation: self-insulating blocks have excellent thermal insulation performance, which can reduce the heat exchange between buildings and the outside world and reduce the energy consumption of winter heating and summer air conditioning.

    2. Saving heating and cooling energy: due to the excellent thermal insulation performance of self-insulating blocks, the internal heat of the building is not easy to lose, saving the use of heating energy.

    Similarly, in summer, self-insulating blocks can also block the entry of external heat, reduce the use of air conditioning and reduce the consumption of cooling energy.

    3. Reduce energy loss: walls of traditional building materials can easily lead to a thermal bridge effect, resulting in energy loss.

    By reducing the thermal bridge effect, self-insulating blocks can minimize energy loss and improve building energy efficiency.

    4. Improve indoor comfort: self-insulating blocks can maintain a constant temperature inside the building, reduce cold and heat imbalance and temperature fluctuations, and improve indoor comfort.

    Generally speaking, using self-insulating blocks can reduce the energy consumption of buildings, reduce energy waste and improve the energy-saving effect of buildings, which is of great significance for sustainable development and environmental protection.

    Self-insulation blocks are widely used in a wide range of fields:

    1. Construction field: self-insulation blocks are widely used in the construction industry. They can be used for thermal insulation of walls, floors, roofs, doors, windows, frames and other building parts, significantly reducing the energy consumption of buildings and improving energy efficiency.

    2. Agricultural field: self-insulation blocks can also be used in agricultural buildings, such as farmland greenhouses, rural houses, warehouses, etc., which can effectively reduce the temperature of farming buildings, moistureproof, warmth and so on.

    3. Industrial field: self-insulation blocks are widely used in industrial buildings, such as power plants, chemical plants, iron and steel plants, paper mills, etc., which can be used for pipe insulation, equipment anti-freezing, storage tank insulation and so on.

    4. Other areas: self-insulation blocks can also be used in gardens, roads, bridges, water conservancies, and other engineering projects.

    In the field of gardens, it can be used to make rockery, fountains and other landscapes; in the area of roads and bridges, it can be used to make slope protection and barriers.

    The above information is for reference only. You can consult the relevant literature for more details.

    Composition of self-insulating block equipment.

    Self-insulating block equipment is mainly composed of the following parts: raw material processing system, block cutting line, automatic packaging machine, control system and so on.

    When these components work together, various specifications and types of self-insulation blocks can be produced efficiently.

    The investment of self-insulation block equipment can be large or small, and the mode of production is flexible: it can not only start with a small amount of mold investment but also can be produced directly on a large scale, not only on a fixed site but also on a relocated site.

    The process of the self-insulating block is simple and easy to operate: the cement foaming is used to mix cement, fly ash, sand and other materials, and special equipment and mold can be used for molding without autoclave maintenance.

    The self-insulation block takes fly ash, slag, sand, aeolian sand, stone powder with low soil content and tailing ceramsite as the primary raw materials, with high waste rate, low cost and high profit.

    At the same time, it also promotes the development of the solid waste treatment industry.

  • What is Cellular lightweight concrete

    The compressive strength of CLWC for a given density is higher, having a high content of fly ash in the mix. It also contributes to strength enhancement by minimizing the volume of pores and uniformly distributed in the mix. Water absorption is high for high compressive strength because, for a given CLWC mix, increased density corresponds to an increase in the paste volume of the capillary pore at the same reduction in the foam volume of the artificial pore. The compressive strength of foamed concrete is mainly a function of dry density and is only slightly affected by the percentage of cement replaced by silica fume. A large proportion of silica fume did not significantly affect the long-term compressive strength. The compressive strength of foam concrete with silica fume is higher than that of foam concrete without silica fume, and the difference in strength between foam concrete with silica and control samples is approximately the same for all ages. K. Krishna Bhavani Siram(2012) carried out his research on Cellular Lightweight Concrete Blocks as a Replacement of Burnt Clay Bricks. The major issues in environmental improvement involve improving the combustion efficiency of existing kilns and upgrading kilns to newer and more efficient process designs. Her study has shown that the use of fly ash in foamed concrete can greatly improve its properties. Most of the cleaner production effort is required in India. Hence, Cellular Lightweight Concrete blocks may be used as a replacement for burnt clay bricks for construction purposes, which is advantageous in terms of general construction properties as well as eco-friendliness. Concluded that Foams formed from protein-based surfactants have smaller bubble sizes, are more stable, and have a stronger closed bubble structure compared to the foam produced using synthetic surfactants. Hence, they are high-strength foam concretes. The density of foam concrete is the function of the volume of foam that is added to the cement paste. The compressive strength of foamed concrete is an inverse function of the density of the material.

    The foamed concrete with denser microstructure and thicker walls

    M. Roderick Jones et al. (2013) investigated that instability increased with reducing foamed concrete density. Stability can be maintained by using a fast setting time and fine particle size cement to produce stable foamed concrete at ultra-low densities. The initial setting time of not more than 25 minutes always resulted in stable foamed concrete with densities down to 150 kg/m³. And time below it, mix set more quickly for practical purposes. Fine fly ash gave stable foamed concrete at ultra-low density compared to coarser fly ash; even the setting time was the same. Also, improves the insulating nature of foamed concrete because it reduces the heat of hydration significantly. For a density of 300 kg/m³, foamed concrete with 30% fly ash absorbs up to 25% more sound compared to foamed concrete having no-fly ash. 30% fine fly ash contained in foamed concrete reduced the thermal conductivity by around 7%, whereas it is just 4% with coarser fly ash for densities of 200 and 300 kg/m³. The difference is due to higher fineness, which improves the bubble structure and yields more closed bubbles. Thermal conductivity increases when fly ash contained is 70% or more. Fly ash also improves the microstructure of foamed concrete after long-term curing. Fly ash of more than 50% yields foamed concrete with denser microstructure and thicker walls. Focused on the thermal conductivity of foamed OPS concrete of density in the range of 1100-1600 kg/m³ and investigated that the thermal conductivity of concrete increases with higher density. The lowest thermal conductivity was found for a density of 1100 kg/m³, which is similar to lightweight concrete with expanded perlite aggregate. Thermal conductivity and compressive strength of density 1500 and 1600 kg/m³ verify the RILEM classification. They can be used as structural and insulating concrete in which tiny air voids introduced due to foam act as an insulator. In low-density foamed concrete, more foam is introduced, resulting in a high amount of air voids in concrete, which is a good insulator. The thermal conductivity of foam concrete is lower than that of conventional blocks and bricks.

     

    Aerated lightweight concrete is unlike conventional concrete in some mix materials

    Aerated lightweight concrete does not contain coarse aggregate, and it possesses many benefits such as low density with higher strength compared with conventional concrete, enhanced thermal and sound insulation, and reduced dead load, which could result in several advantages in decreased structural elements and reduced transferred load to the foundations and bearing capacity. Foamed concrete is different in the agent of forming air voids as compared with AAC. Foam agents form the air voids in foamed concrete; this operation is physical processing. Against the air voids in AAC formed by the addition of aluminum powder to the other materials and the reaction between them, this operation is chemical processing. The air voids are homogenous and distributed within aerated lightweight concrete. Aerated lightweight concrete is considered the economy in materials and consumption of by-products and waste materials such as fly ash. P. S. Bhandari et al. (2014) carried out research on CLWC in terms of density and compressive strength and concluded that compressive strength for CLWC is low for lower-density mixtures. The compressive strength of 53-grade cement is slightly higher than 43-grade cement, but as strength increases, its density also increases. CLWC is acceptable for framed structure. CLWC can be suitable for earthquake areas.
