Main performance


■ The liquid dosage is 1.0%-2.5% of total cementitious materials.
■ Mixed with this product under the same water-cement ratio,can increase the slump of concrete by more than 10cm. Under the same amount of cement and the same slump, the strength of concrete can be increased by 40%-70% in three days, by 30%-60% in seven days, and by 25%-50% in 28 days.
■ The loss of slump over time is small, which can meet the long-distance transportation of commercial concrete.
■ Workability, water retention and cohesion are greatly improved, no delamination and no segregation.
■ Initially there is a retarding effect. It can reduce the early hydration and heat release rate of concrete, which is beneficial to the pouring of large-volume concrete.
■ The compressive strength, flexural resistance, tensile strength, impermeability and durability of concrete have been significantly improved.
