What are concrete admixtures? Concrete admixture refers to the material added before mixing concrete or in the mixing process, which can be used to improve the performance of new mixed concrete or hardened concrete. A small amount of admixture can improve some properties of concrete, such as improving workability, adjusting the setting time, improving the strength and durability, saving cement, etc. The characteristics of concrete admixture are many varieties and small amounts, and the performance of concrete has the characteristics of less investment, quick effect, and remarkable technical and economic benefits. It can improve the carbonization resistance of concrete, and there is a linear relationship between the carbonization depth and porosity of concrete; it greatly influences the freezing resistance of concrete. Concrete mixed with gas and water reducing agent is good, without improving the freezing resistance of concrete.
Main uses of concrete admixtures Concrete admixture can improve the affinity of concrete. With a water-reducing and air-guiding agent, liquidity can be greatly improved without changing the concrete mix ratio and strength, which is beneficial to construction, improve quality and, reduce the labor strength, adjust the hardening speed of concrete setting. Adding admixture can reduce the curing time of concrete, remove the formwork and prestressed reinforcement in advance, and shorten the construction period. Adding a retarder can delay the setting time of concrete so that the concrete of high-temperature construction is good and convenient. The use of retarder in a large number of concrete can prolong the release time of hydration heat and avoid surface cracks; adjust the air content in concrete, the admixture can increase the appropriate gas content of concrete, the anti-foam agent can reduce the air content in concrete, and the use of air guiding agent can prepare light porous concrete; improve the physical and mechanical properties of concrete: for example, the filling agent can improve the frost resistance, seepage resistance and crack resistance, and the use of frost agent can ensure the normal condensation hardening of concrete in the low-temperature environment below 0, and the waterproof agent can be used in concrete. Category of concrete admixture: Fixture to improve the performance of concrete mixing logistics. Including various water-reducing agents, air suction agents, and pumping agents; admixture regulating concrete setting time and hardening performance. Including retarder, early strength agent, and quick setting agent; admixture to improve concrete durability. Including air agents, waterproof agents, and rust inhibitors; admixture to improve other properties of concrete. Including filling agent, expansion agent, colorant, antifreeze, waterproof agent, and pumping agent. Price of concrete admixtures The different price of concrete admixtures purity is also different.
