Widely used in concrete engineering, prefabricated, sleeper, bridges, tunnels, national defense, military engineering, water conservancy, power engineering, port terminals, airport runway, high-rise building engineering.

Dosage: 0.5%-0.8%, the user should according to the need to experiment to determine the optimal dosage.

Remarkable Plasticity: Statistically, compression strength on the 1stday, the 3rd day and 28th day after single application is increased by 60%-90% and 25%-60% respectively when it is added at standard blend dosage. As the result, compression strength, tensile strength, buckling strength and modulus of elasticity will be improved to some extent.

Under the condition of same water/cement ratio, collapsibility can be increased 5-8 times when it is added at 0.75% blend dosage.

15-20% of cement can be reserved when the agent is blended at 0.75% blend dosage, which is preconditioned by same collapsibility and strength.
