The leading foam concrete, lightweight concrete additives supplier |
3D Printing Metal Powder


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.

  • The earliest well-known use of concrete is a floor dating back to Galilee, around 7000 BC, which was still audio when uncovered in 2007. After thousands of years of use as a building material, science could develop something better. This material wouldn't crack or crumble when used on columns or sidewalks.

    Science can, says Christopher Ferraro, a civil engineering researcher at the University of Florida.

    The problem is that many stronger or more durable materials than concrete provide no clue that something is wrong. Ferraro said cracks in concrete are a sign that can save lives.

    Concrete can show signs of distress. It will start to crack and peel, which is a sign to pay attention and is time for maintenance.

    Concrete made the reports when the Champlain Towers South in Surfside, Florida, collapsed in June. Attention was focused on the condition of the concrete and steel structures as they showed signs of wear and tear. Concrete will continue to be in the news as a massive federal infrastructure spending package takes shape, with much of the spending going toward structures made of concrete.

    The climate crisis has also focused on concrete contributing to greenhouse gas emissions. Still, Ferraro said that America today has a respectable document compared with other industrialized countries. For instance, China utilized as much concrete between 2011 and 2013 as the USA used in the 20th century.

    While it's unlikely that any other material will replace concrete anytime soon, the science of concrete aims to make the world's most popular building material stronger, more durable, and more sustainable.

    Ferraro points out that many of the failures blamed on concrete are not due to concrete at all but to concrete's near-constant partner: steel.

    As an expert engineer and specialist who often testifies on all things concrete from New York City to Florida, Ferraro states he has seen his share of concrete repair services, 95 percent of all strengthened concrete frameworks being repaired because of the steel framed in them. Brought on by destruction. When steel rusts, two points occur. First, the iron develops into iron oxide. Then, the iron oxide broadens as much as seven times its initial dimension. The expansion pushes against the concrete, causing spalling or cracking. Ferraro said when you see cracks in reinforced concrete, it's often because the underlying steel bars are expanding.

    Concrete lasts a long time; it's the steel that fails

    Concrete and steel are used together to provide both strengths. The concrete handles the compressive load, which is the structure's weight, and the steel handles the tensile load, allowing for some flexibility. Combining concrete and steel provides structural strength that is difficult to surpass.

    The ingredients in concrete recipes are among the most common raw materials on the planet. It is made of limestone, sand, and clay-made cement. Concrete is made from cement, plus sand, gravel, and water. This makes cement—especially Porter Blue cement - a key research focus.

    Research in the Ferraro Laboratory in the School of Sustainable Infrastructure and Environmental Engineering focuses on nondestructive testing, alternative binders and aggregates, infrastructure conditions, and virtual testing and modeling of concrete microstructures.

    Traditionally, Portland cement is combined with Potsdam, a material with cohesive properties when combined with water. One of the most effective and common admixtures is fly ash, a by-product of coal-fired power plants. Fly ash has the added benefit of recycling coal-fired waste products. Rather than being released into the air or landfilled, fly ash is used to make concrete, which is added to make the concrete more durable. However, as coal burning decreases, there will be demand for alternatives to fly ash.

    Some alternative stuccoes are crushed recycled glass and different types of clay. Since South Florida has a large sugarcane crop, bagasse, a waste product from sugarcane farming, is also being studied. Ferraro is looking for alternative cements that are structurally appropriate, plentiful, readily available and cost-effective.

    "We know that without fly ash, Portland cement itself is not very durable, so we are looking for alternatives," Ferraro said.

    Concrete is porous, and fly ash does a very good job of protecting the steel encased in the concrete from chlorides that seep into the concrete layer. For example, coastal bridge towers are located in saltwater chloride-rich environments.

    Fly ash gives us a long time for corrosion to start and, therefore, extends the life cycle of the concrete.

  • As one of the world's largest water conservancy projects, the Three Gorges Dam's stability and safety have always attracted much attention. In recent years, due to the impact of long-term reservoir load operation and crustal activity, the Three Gorges Dam has experienced some crack problems, which have posed new challenges to the dam's stability. To ensure the stability and safety of the dam, relevant departments have adopted a series of comprehensive measures to deal with cracks, which have achieved remarkable results.

    Experts have conducted comprehensive research and analysis on the crack problem of the Three Gorges Dam. Through on-site surveys and monitoring, they conducted in-depth research on cracks' shape and expansion trends and the potential safety hazards they may cause. On this basis, they proposed a technical solution for crack treatment to ensure the reliability and durability of the repair effect.

    Anti-crack Agent 

    Experts have adopted corresponding treatment methods for different types of cracks. For smaller surface cracks, caulking materials are used to repair them; for deeper and wider cracks, grouting and grouting technology are used to inject high-strength materials into the cracks to enhance the overall structural stability of the dam. At the same time, methods such as grouting, anchor cables, and reinforcement were used to reinforce the cracks, effectively improving the dam's seismic and erosion resistance.

    In addition to proactively dealing with the crack problem, relevant departments have also strengthened the dam's monitoring and early warning system. They installed scientific equipment, such as crack sensors and deformation instruments, at strategic locations to monitor the deformation and displacement of the dam in real time. Once an abnormality is discovered, appropriate measures should be taken immediately to repair and reinforce the dam to ensure its safe operation.

    To improve the dam's stability, relevant departments have also conducted large-scale ecological environment restoration work. They built a large area of vegetation coverage, planted grass and trees, and strengthened ecological environment protection around the reservoir. This not only helps reduce the occurrence of geological disasters but also improves the dam's erosion resistance, further ensuring its stability and safety.

    Anti-crack Agent 

    The above comprehensive measures have effectively guaranteed the stability and safety of the Three Gorges Dam. In recent years, the dam has experienced no major crack expansion or safety accidents, completed many flood control tasks, and played an important role in the country's economic development and social stability.

    However, we also need to realize that treating cracks in the Three Gorges Dam is only temporary. In the long term, monitoring and maintenance work needs to be strengthened to promptly repair and strengthen new cracks to ensure the long-lasting stability of the dam.

    The main function of concrete anti-cracking agents is to improve the anti-cracking performance of concrete.

    Enhance the anti-crack efficiency of concrete: Anti-crack representatives can create a particular fiber framework in concrete, properly enhancing its tensile stamina, therefore enhancing its anti-crack efficiency.

    Decrease the contraction deformation of concrete: Concrete will certainly reduce and deform throughout the drying-out procedure, and this contortion will cause cracks in the concrete. Anti-crack agents can manage the shrinkage and deformation of concrete, thereby decreasing concrete fractures.

    Enhance the toughness of concrete: This allows it to resist erosion from various environmental factors during use, increasing its service life.

    Increase the plasticity of concrete: Anti-cracking agents can improve the fluidity of concrete, make the concrete more uniform during pouring, and reduce voids and defects within the concrete. This avoids over-vibration, one of the causes of cracks in concrete. Excessive vibration can separate the aggregate within the concrete, causing cracks in the concrete.

    Enhance the toughness of concrete: Using anti-cracking agents can improve the toughness of concrete, making the concrete have better flexibility and tensile properties when stressed, thereby reducing concrete cracking.

  • The impact of aggregate selection on concrete is a complex topic, not just one aspect of strength. The following is a detailed analysis of this topic, hoping to help you better understand it.

    Effect of Aggregate on Concrete Strength

    Aggregate is the main component of concrete, accounting for 70% to 80% of the volume of concrete. According to different particle size ranges, aggregates can be divided into fine aggregates (sand) and coarse aggregates (gravel or pebbles). The choice of aggregate directly affects the strength of the concrete.

    Strength and durability: Aggregate firmness, particle size distribution and cleanliness are all important factors affecting the strength of concrete.

    Resistance to Cracking: The modulus of elasticity and coefficient of thermal expansion of aggregates have a significant effect on the resistance of concrete to cracking. The selection of aggregates with a modulus of elasticity and coefficient of thermal expansion similar to that of cement paste can reduce the risk of concrete cracking.

    Workability: Aggregate size and gradation affect the workability of fresh concrete.


    Effect of aggregates on other properties of concrete

    Shrinkage and creep: the modulus of elasticity of aggregates has a certain effect on the shrinkage and creep of concrete. Aggregate with a high modulus of elasticity can limit the shrinkage and creep of concrete and improve the long-term stability of the structure.

    Durability: Aggregate water absorption, mud content and other factors affect the durability of concrete. Aggregates with low water absorption help reduce the permeability of concrete and improve resistance to chloride attack and freeze-thaw cycles.

    Economy: The price of different types of aggregates varies greatly. Under the premise of meeting engineering requirements, the selection of local economic aggregates can reduce project costs.

    Environmental: Selecting aggregates that meet environmental standards can help reduce carbon emissions in the concrete industry. For example, the use of recycled aggregates to replace natural aggregates can reduce the impact of mining on the environment.


    How to choose the right aggregate

    Understand the engineering requirements: According to the engineering requirements, such as the type of structure, the use of the environment, the design life, etc., select the appropriate aggregate. For example, for structures subject to heavy loads or requiring long-term durability, aggregate with stable quality and high strength should be selected.

    Consideration of geographic factors: There are differences in the quality of aggregates from different regions and quarries. When selecting aggregates, the influence of their origin, transportation distance and local environmental conditions should be considered.

    Test and verification: Before deciding to use a certain aggregate, it is very necessary to conduct tests and verification. By comparing the performance of concrete prepared with different aggregates, its suitability and economy can be assessed.

    Compliance with Codes and Standards: Compliance with national and local industry codes and standards ensures the quality and reliability of the aggregate selected. In addition, when adopting non-traditional aggregates or recycled aggregates, corresponding assessment and verification should be carried out.

    Sustainability and environmental protection: Prioritize the use of environmentally friendly and renewable aggregate resources on the premise of meeting project requirements. Prioritize helps to reduce the environmental impact of the concrete industry and promotes the goals of green building and sustainable development.


    To summarize, aggregate selection not only affects the strength of concrete but also has a comprehensive impact on the workability, durability, economy, and environmental impact of concrete. Therefore, thorough consideration and comprehensive assessment are required when selecting aggregates to ensure that the performance of the prepared concrete meets the project requirements and achieves the goal of sustainable development.

  • The Three Gorges Dam is one of the largest water conservancy projects in the world and the pride of China. However, problems with cracks have persisted since the dam was built, raising concerns about its stability. To ensure the safety and reliability of the dam, scientists and engineers have actively researched and implemented a series of overall crack reinforcement plans.

    Cement Anti-crack Agent Preventing Cracks in Foam Concrete 

    Reinforcement of the dam's skeleton structure. The main skeleton structure of the dam is made of concrete, so it is very important to repair and reinforce the concrete. Scientists have found through research that the occurrence of cracks is mainly related to the strength and quality of concrete. They utilized new high-strength concrete products, which increased the dam's overall toughness and improved its crack resistance. They used innovative grouting modern technology and support products to fill and repair splits, improving the dam's stability.

    The strengthening of earthquake-resistant facilities is also an important means to improve the stability of dams. It is one of the important factors threatening dam safety. To cope with the vibration and stress caused, scientists and engineers designed and installed a series of earthquake-resistant facilities. They increased the thickness of the dam's foundation foundation and used stronger geological materials for support.

    They mounted a series of shock-absorbing gadgets, generally the framework of the dam, which can efficiently take in and spread wave energy and decrease the impact on the dam. They also comprehensively upgraded the dam's pipeline and control systems to ensure rapid response and reduce the occurrence of accidents.

    Cement Anti-crack Agent Preventing Cracks in Foam Concrete 

    In addition to strengthening the dam's skeleton structure and anti-seismic facilities, management and monitoring are important links in ensuring the dam's stability. Relevant departments have established a complete monitoring system to monitor the dam's cracks, displacement, stress, and other indicators in real time to grasp the dam's status promptly. Once an abnormality is discovered, take appropriate measures immediately to prevent the problem from expanding further. Enhance dam administration and conduct regular repair work and upkeep jobs to ensure the normal operation and protection of the dam.

    The total reinforcement of splits in the 3 Gorges Dam enhances stability by reinforcing the dam's skeletal system framework and anti-seismic centers. These measures include using high-strength concrete materials, grouting to repair cracks, increasing the thickness of foundations, and setting up shock-absorbing devices. At the same time, the management and monitoring of dams cannot be ignored. Only by maintaining good maintenance and detecting problems promptly can the safe and reliable operation of the dam be ensured. With the continuous growth of science and technology and the improvement of engineering technology, the Three Gorges Dam will continue to create more economic and social benefits for people.
