Cement based water reducing agent is a commonly used additive for concrete and cement products, which can reduce the amount of cement used in concrete while maintaining its strength and workability.
The main components of common cement base water reducing agents include the following categories:
Retarder: retarder can delay the setting time of cement slurry, allowing the initial and final setting times of concrete to be regulated. Common retarders include sugars, sucralose, and starch.
Dispersant: Dispersant can reduce the surface tension between cement particles, making it easier to disperse in water. This can increase the plasticity and flowability of concrete. Common dispersants include sulfonates, polycarboxylates, and their derivatives.
Hydration regulator: Hydration regulator can regulate the process of hydrate formation in cement, thereby affecting the strength development of concrete and the stability of cement colloids. Common hydration regulators include silicates, sodium hydroxide, etc.
Binder: Binder can increase the adhesion ability of cement colloids, improve the bonding strength and impermeability of concrete. Common binders include polymer lotion, acrylate copolymer, etc.
By properly mixing and using cement based water reducing agents atmp , the effects of reducing cement dosage, improving concrete performance, and reducing concrete shrinkage can be achieved. During use, the correct dosage and control should be carried out according to the specific concrete mix ratio and work requirements, and in accordance with the instructions provided by the manufacturer, to ensure that the quality and performance of the concrete meet the design requirements.
