Water reduction agent HEDP is a chemical additive that is commonly used in concrete and cement products. It can reduce the amount of water while maintaining the liquidity of concrete. The principle of the role of water reduction agent mainly includes the following aspects:
Diversified effects: The active ingredients in the water reducing agent can interact with the tape -strip ions on the surface of the cement particles to form a layer of adsorption layer. This adsorption layer can neutralize the charging part of the surface of the cement particles, reduce the attractiveness of static electrostatic between the particles, so that the cement particles are dispersed evenly.
Reduce adhesion force: Due to the decentralized effect of a water reduction agent, the adhesion between cement particles is reduced, which increases the liquidity of the concrete, and it is easy to construct and pour.
Surface tension regulation: The water reduction agent can reduce the surface tension of the water, so that the water can better disperse and wet the particles in the concrete, and improve the liquidity of the concrete.
Reduce the adsorption of cement collagen: The active ingredients in the water reducing agent can have a chemical reaction or complex with the cement collagen, reduce the adsorption force between the colloidal particles and the molecule, and improve the liquidity of the concrete.
In general, the water reducing agent can improve the effect of water regulating the nature of water, and the chemical reaction with the occurrence of cement collagen by improving the interaction between cement particles, thereby achieving the effect of reducing water consumption and increasing concrete liquidity. This can not only meet the needs of construction, but also ensure the strength and durability of the concrete.
