use method
1. Generally, the powder is dissolved into 30-35% liquid for use. The best dosage is found out through experiments, and the recommend dosage is 1.5-2%;
2. Aliphatic superplasticizer (powder) and mixing water are added to the concrete together. Post addition can also be adopted. The concrete added with aliphatic superplasticizer (powder) should be stirred for 30s longer;
3. Due to the large water reduction rate of aliphatic superplasticizer (powder), a layer of yellow slurry will be secreted on the surface before the initial setting of concrete, which is a normal phenomenon. After the concrete is collected and plastered, the color will be eliminated, or after the strength of the concrete is applied, the color will be eliminated naturally, and the watering and curing color will be eliminated faster, without affecting the internal and surface properties of the concrete.
performance characteristics
1, high water reduction rate. The water content is 0.5-1%, and the water reduction rate can reach 15-25%. Under the same slump conditions, the addition of aliphatic superplasticizer (powder) can save 25-30% of cement consumption;
2, early strong, enhance the effect is obvious. Concrete mixed with aliphatic high-efficiency water reducing agent (powder), three days can reach 60-70% of the design strength, seven days can reach 100, 28 days than the blank concrete strength increased by 30-40%;
3, high protection plastic. The slump loss of concrete with time is small, basically no loss in 30 min, and 10-20% loss in 90 min;
4, the wide applicability of cement, workability, good cohesion. Good compatibility with other types of admixtures;
5, can significantly improve the concrete freeze-thaw resistance, impermeability, resistance to sulfate erosion, and comprehensively improve the other physical properties of concrete;
6, especially suitable for the following concrete: fluid plasticized concrete, natural curing, steam curing concrete, impermeability waterproof concrete, durable freeze-thaw resistant concrete, sulfate erosion resistant marine concrete, as well as reinforced, prestressed concrete;
7, aliphatic superplasticizer (powder) non-toxic, non-combustible, non-corrosive steel, no sodium sulfate crystallization in winter.
