Water reduction is a chemical additive that is commonly used in concrete and cement products. It can effectively change the liquidity of concrete and reduce the water -asx ratio, thereby improving the working performance and strength of the concrete. The water reducing agent is usually composed of the following main components, and each component has its own unique effect:
Regulating agent: The regulator is one of the key ingredients in the water reduction agent. It can adjust the effect of the water reduction agent and meet the needs of different concrete materials. The role of regulators includes controlling condensate time, improving crack resistance, and increasing plasticity of concrete.
Surface active agent: Surface active agent is one of the most important ingredients in the water reducing agent. They can form a adsorption layer on the surface of the concrete particles, so that the particles have negative charge, thereby inhibiting the electrostatic attraction between the particles, improving the liquidity of the concrete Essence
Different agents: Dispenses are a type of adhesion that can decentralize the adhesion between cement particles. They have a chemical reaction with the surface of the cement particles to change their surface properties, separate the particles separately and maintain the dispersing state, thereby improving the liquidity of the concrete Essence
Slow -coagulant: Slow -coagulant is a type of component that can extend concrete condensation time. In some cases, such as large concrete or remote transport, you need to use a slowing agent to delay the concrete process of the concrete in order to ensure sufficient working time and appropriate liquidity.
Anticoagulants: anticoagulants are a type of component for controlling concrete condensation speed. They can prevent concrete condensation prematurely under high temperature, high humidity or rapid construction conditions, and provide sufficient working hours.
The combination and proportion of these main ingredients will be adjusted according to specific applications and needs to achieve the best water reduction effect. The correct use of water reducing agents can improve the quality and working performance of concrete, but it is necessary to follow the suggestions and specific use instructions of the manufacturer when used.
