Construction:
When the concrete strength and slump are basically the same, the amount of cement can be reduced by 10-25%.
When the water-cement ratio remains unchanged, the initial slump of the concrete is increased by more than 10cm, and the water reduction rate can reach 15-25%.
It has significant early strength and strengthening effect on concrete, and its strength increase range is 20-60%.
Improve the workability of concrete and comprehensively improve the physical and mechanical properties of concrete.
Good adaptability to various cements and good compatibility with other types of concrete admixtures.
It is especially suitable for use in the following concrete projects: liquid concrete, plasticized concrete, steam-cured concrete, impermeable concrete, waterproof concrete, natural-curing precast concrete, steel and prestressed reinforced concrete, high-strength ultra-high-strength concrete.
The slump loss of concrete is large over time, and the slump loss in half an hour is nearly 40%.
In addition, because the product has the characteristics of high dispersibility and low foaming, it can also be used as a dispersant in many fields.
It is mainly used as a dispersant in disperse dyes, vat dyes, reactive dyes, acid dyes and leather dyes. It has excellent grinding effect, solubilization and dispersibility. It can also be used as a dispersant for textile printing and dyeing, wettable pesticides, and a dispersant for papermaking. Electroplating additives, latex, rubber, water-soluble paint, pigment dispersant, petroleum drilling, water treatment agent, carbon black dispersant, etc.
