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.
Concrete is a common building material that consists of cement, aggregate, fly ash, admixture, and water. Water plays an important role in concrete; it is not only an important component of concrete but also plays an important role in the performance and quality of concrete.
Water plays the role of cementing material in concrete
The cementitious material of concrete is mainly hydrated and hardened cement colloid, and water is the basis of the hydration reaction of cement. In the process of making concrete, water reacts with cement to form hydration products, which gradually solidify and harden the concrete. The quality and amount of water directly affect the strength and durability of concrete. Too little water will cause the concrete to be difficult to fully hydrate, affecting its strength and stability, while too much water will cause the concrete to be too thin, prolonging the setting time and reducing its strength.
Water plays the role of wetting the aggregate in concrete. Aggregate is the main filler of concrete, and water can clean the dust and impurities on the surface of the aggregate, make the surface of the aggregate wet, and improve the bonding of concrete. At the same time, water can also make the particles of concrete dispersed uniformly, reduce the voids between aggregates, and improve the compactness and strength of concrete.
Water can also affect the fluidity and plasticity of concrete. According to the use requirements of concrete, the fluidity of concrete can be changed by adjusting the amount of water. The right amount of water can make the concrete easier to construct and pour and improve the working performance; too much water will make the concrete too mobile, difficult to control, and even cause delamination and leakage phenomenon; too little water will make the concrete dry, difficult to fill the template uniformly, affecting the construction quality.
Water in concrete can also affect the shrinkage and anti-cracking properties of concrete. Cement in the hydration process will produce contraction, and the right amount of water can relieve the contraction stress of concrete and reduce the contraction deformation and cracking tendency of concrete; too much water will lead to increased contraction of concrete, increasing the risk of cracking.
The effects of too much water on concrete are mainly manifested in the following aspects
Destruction of the ratio: if too much water is added to the concrete, it will destroy the original ratio, increasing the water-cement ratio. This will affect the strength and durability of the concrete and have a serious impact on the quality of construction.
Formation of weak layer: If the mixing is not uniform after adding water, a part of the concrete is easy to forms a weak layer, resulting in an uneven overall strength, which has a serious impact on the overall strength.
Reducing density and waterproof performance: Adding too much water will reduce the density of the concrete, and the waterproof performance will also be affected. Especially before the concrete is solidified, this situation will be more serious.
Water segregation: too much water will lead to water segregation in concrete, resulting in uneven distribution of hardened concrete structures, further affecting the durability and mechanical properties of concrete.
In addition, too much water in the concrete may also affect the workability of the concrete, so that the concrete is too dense, has poor molding quality, has an unsightly surface, and easy to causes construction difficulties.
In order to avoid the above problems, the preparation of concrete must use appropriate water consumption. In the actual project, due to improper preservation of sand and gravel materials or weather changes, the water content of sand and gravel materials will also change dramatically, so in the actual project, the determination of the water content of concrete is of great significance. At the same time, the phenomenon of adding too much water or deducting cement in order to obtain better working performance should also be avoided to ensure that the project can be implemented according to the experimentally formulated ratio.

"High Slump Retaining Concrete Superplasticizer Admixture" usually refers to a type of concrete superplasticizer Admixture; the main function of this admixture is to provide High Slump Retaining and Superplasticizing effects. In concrete engineering, slump is an index to measure the consistency or fluidity of concrete. It describes the extent to which freshly mixed concrete collapses under certain conditions. A high slump means the concrete is more fluid and easier to pour and fill formwork. After some concrete is placed for some time, its slump will be reduced; that is, the fluidity will be reduced. Slump retention admixtures can slow down or prevent the reduction of this slump, ensuring that the concrete maintains its initial fluidity over a longer period.Superplasticizer is an admixture that can significantly improve the fluidity of concrete. It does this by reducing the friction and cohesion between the particles in the concrete, making it easier for the concrete to flow and pour.
High Slump Retaining Concrete Superplasticizer Admixture
With the rapid development of the construction industry, the demand for concrete performance is also increasing. Recently, a new high-performance Concrete Admixture called "High Slump Retaining Concrete Superplasticizer Admixture" has been successfully applied in a number of large-scale construction projects, significantly improving construction efficiency and concrete quality.
It is understood that a well-known domestic building materials company develops this new concrete admixture through a unique chemical formula and preparation process to achieve the perfect combination of high slump retention and super plasticizing effect. After adding this admixture to the concrete, the concrete can maintain high fluidity for a long time, effectively solving the problem of reducing the slump of the concrete during long-term transportation and pouring and ensuring the uniformity and compactness of the concrete in the pouring process.
The additive plays an important role in the construction of a landmark skyscraper. Due to the scale of the project, concrete had to be transported from a distance to the construction site, and the pouring work lasted several hours. In the process of transportation and pouring, traditional concrete often appears the problems of slump reduction and poor fluidity, which brings great challenges to construction. However, by using this new admixture, the concrete always maintains a high fluidity during transportation and pouring, which not only improves construction efficiency but also ensures the consistency of concrete quality.
In addition, in a number of Bridges, tunnels and other infrastructure construction projects, the admixture has also shown excellent performance. Because these projects usually need to be constructed in complex geological environments and harsh climatic conditions, the performance of concrete is extremely demanding. By using this new admixture, the concrete can maintain good fluidity and stability under various extreme conditions, providing a strong guarantee for the smooth progress of the project.
New high performance concrete admixtures are applied to tunnel construction
Industry experts said that the successful application of this new high-performance concrete admixture marks an important breakthrough in the field of concrete admixture research and development in China's building materials industry. In the future, with the development and application of more high-performance concrete admixtures, China's construction industry will usher in a broader development prospect.
