Water reducer is a kind of concrete admixture which can reduce the mixing water consumption while maintaining the slump of concrete unchanged. Most of them belong to anionic surfactants, such as lignosulfonate, naphthalene sulfonate formaldehyde polymer and so on. Adding concrete mixture can disperse cement particles, improve its workability, reduce unit water consumption and improve the fluidity of concrete mixture; Or reduce the unit cement consumption, saving cement.

It is suitable for pumping or normal concrete projects with strength grade of C 15~C60 and above. It is especially suitable for preparing concrete projects with high durability, high fluidity, high slump resistance, high strength and high requirements on appearance quality. It is very beneficial for preparing high fluidity concrete, self-compacting concrete and fair-faced concrete.

Ordinary water reducing agent is suitable for concrete with daily minimum temperature above 5℃. The superplasticizer is suitable for concrete with daily minimum temperature above 0℃, and is also suitable for preparing high fluidity concrete, high strength concrete and steam curing concrete.

Performance characteristics:

1, low dosage, high water reduction rate, and the water reduction rate can be as high as 45%;

2. The slump loss is small with time, and the slump loss rate of ready-mixed concrete 1h is less than 5% and 2h is less than10%;

3. The reinforcement effect is remarkable. The compressive strength of concrete is increased by 50 ~110% in 3d, 40 ~ 80% in 28d and 30 ~ 60% in 90d.

4, concrete workability is excellent, no segregation, bleeding phenomenon, concrete appearance color is uniform. When used to prepare high-grade concrete, the concrete has good cohesiveness and is easy to mix;

5, moderate air content, no adverse effect on the elastic modulus of concrete, good frost resistance and durability;

6, it can reduce the early hydration heat of cement, which is beneficial to mass concrete and summer construction;

7. Excellent adaptability, good compatibility between cement and admixture, good temperature adaptability and good compatibility with different kinds of cement and admixture, which solves the problem of poor compatibility between other water reducing agents and cementitious materials.
