1.Water reducers with different slump retention effects can be compounded with mother liquor as required.
2.The usual dosage is 0.6%-1.2% (calculated based on the total amount of cementitious materials). The optimal dosage should be determined by experiment according to the engineering materials and characteristics.
3.It is suitable for compounding use of high water reducing polyslump carboxylic acid water reducing agent.
4.The water reducing agent can be dissolved in water or added separately to the concrete mixer.
Polycarboxylic acid superplasticizer—slump-preserving type
This type water reducing agent can be widely used in pumping concrete, super-fluid self-compacting, high-strength and high-performance concrete and commercial concrete, with a concentration of 38%-40%. When you store, need to notice that prevent leakage, exposure and high temperature during storage.
How to use standard type water reducing admixture
1.The powder content is 0.3-0.7% of the total glue, and the liquid content is 1.0-1.2% of the total glue volume.
2.Concrete water reducing admixture need to be added with the mixing water into the mixer and stir until the specified time.
Advantages of standard type water reducing admixtures
1.The water reducing agent in concrete has good water-reducing performance at low content, especially in high-grade concrete, and its maximum water-reducing rate can reach 40%.
2.Water reducing admixture for concrete is alkali-free and chlorine-free, and has no corrosion hazard to steel bars.
3.It has a strong dispersing effect on cement, which improves the fluidity of the mixture, and the concrete slump can reach 20-25mm.
4.Compared with the benchmark concrete, the bleeding of concrete mixed with this water reducing agent is significantly reduced, and there is no segregation phenomenon, which makes it easier to achieve construction operations.
5.The density of cement water reducer is 1.08-1.12KG/1, the PH value is 6.0-8.0, the solid content is 40%, and there is no residual harmful chemical substances.
Ways to pack and store standard water reducing chemical admixtures
1.Liquid products are packed in bulk or barrels according to users’ requirements.
2.Store water reducer in a cool and dry place, avoid direct sunlight.
3.The shelf life of this water reducing agent in concrete is one year, and the expiration date should be confirmed through experiments.
