1. Improve the fluidity and workability of concrete and make it easier to construct and process.
2. Improve the strength and durability of concrete to make it stronger and more durable.
3. Enhance the crack resistance and impermeability of concrete, thus reducing the cracking and leakage of concrete.
4. Improve the durability and wear resistance of concrete to make it more durable and wear-resistant.
5. Improve the frost resistance and durability of concrete, and make concrete more suitable for use in harsh environment.
Types of cement concrete admixture
According to different functions and uses, cement concrete admixtures can be divided into the following categories:
1. water reducer: water reducer is an additive that can improve the fluidity and workability of concrete, and can reduce the viscosity and surface tension of concrete, thus improving the fluidity and workability of concrete.
2. Reinforcing agent: Reinforcing agent is an additive that can improve the strength and durability of concrete. It can improve the physical and chemical properties of concrete, thus improving the strength and durability of concrete.
3. Waterproofing agent: Waterproofing agent is an additive that can improve the impermeability of concrete, improve the pore structure and surface tension of concrete, and thus reduce the leakage of concrete.
4. Antifreeze: Antifreeze is an additive that can improve the frost resistance of concrete. It can improve the pore structure and frost resistance of concrete, thus reducing the cracking of concrete.
Operation steps of cement concrete admixture
When using cement concrete admixture, the following steps must be followed:
1. Calculate the required amount of admixture according to the concrete mixture ratio.
2. Add the admixture into the concrete and mix it fully with the concrete until it meets the required performance requirements.
3. In the process of concrete construction, additives should be added as needed to ensure the stability of concrete performance.
4. After the concrete construction is completed, it should be cured in time to ensure its stable performance and long-term use.
