Types and characteristics of polycarboxylate superplasticizers

1. High water reduction type: (1) Ultra-high water reduction rate, the water reduction rate can reach 40%; (2) The enhancement effect is obvious, the 3d compressive strength can be increased by 150%-200%, and the 28d compressive strength can be increased by 40% %-70%.

2. High slump protection type: (1) No loss within five hours at most, and the initial and final setting time of concrete is extended by 5 to 12 hours according to the T requirements; (2) It is compounded with high water-reducing polycarboxylate water-reducing agent It can better meet the working performance and mechanical properties of concrete after hardening; (3) It is suitable for mass concrete, self-compacting concrete, medium and low slump concrete, high-strength concrete, etc. for construction under hot weather conditions.

3. Anti-mud slow-release agent: (1) Excellent mud resistance, has a significant effect on sand and gravel with high mud and stone powder content, and reduces the slump loss of concrete; (2) It is suitable for sand and gravel materials containing mud and stone powder It is the parent material of composite concrete admixtures for high-volume pumping concrete projects and precast concrete components.
