Functional functions of concrete pumping agent

In pumping concrete, it can significantly improve the workability and cohesion of concrete, reduce the friction resistance between concrete and pipelines, and reduce slump loss.

Concrete pumping agent classification: retarding type, early strength type.

1. Dosage: Concrete grade C40-C60 accounts for 2.5-3.5 of the cementitious material

2. Function: Mainly used in various strength levels and types of concrete to play a role Water reduction, pumping, cement saving and other functions.

3. Technical performance:

1. Mixed with concrete pumping agent, the slump value is greater than 200MM.

2. The 30-60 minute slump retention value of concrete prepared with concrete pumping agent is greater than 180MM.

3. The water reduction rate reaches more than 15, and can be configured with ordinary and high-strength Concrete.

4. The anti-permeability level of concrete mixed with concrete pumping agent can be increased by 2-4 levels.

5. Keeping the design strength level of concrete unchanged can save the amount of cement.

6. Mixed with pumping water agent, it has good pumping effect and the condensation time is delayed by more than 2 hours. Mixed with concrete pumping agent, at the standard testing temperature, the design strength can reach 70 in 3 days, 100 in 7 days, and 115 in 28 days

IV. Implementation standards: JC 473-2001
