1.Remarkable Plasticity: As a condition of blending where amount of cement and collapsibility are fixed aforehand, mixing water can be decreased by 17-25% when it is admixed with reinforced concrete at 0.5-1.0%. Statistically, compression strength on the lst day, the 3 rd day and the 28 th day after single application is increased by 60-95% and 25-50% respectively when it is added at standard blend dosage. As a result, compression strength, tensile strength, buckling strength and modulus of elasticity will be improved to some extent.
2. Improve miscibility of concrete amalgamator with water and collapsibility as well. As a condition of equivalent blending, collapsibility can be increased 4-7 times when it is added at 0.7% blend dosage.
3. 15-20% of cement can be reserved when the agent is blended at 0.7% blend dosage, which is preconditioned by same collapsibility and strength.
