Slump Retention Polycarboxylate Superplasticizer 50%

Technical Principle

Depending on their purpose, these admixtures can be classified as water reduction agents, accelerators, retarders, waterproofing agents, expansion agents, defoaming agents, and moisture-proofing agents.

The following are the primary purposes of polycarboxylate superplasticizer:

1. Make concrete more workable to accommodate the construction location;

PCE has a comb-like molecular structure. The cement particles absorb the high-performance polycarboxylate superplasticizer molecules from the main chain, which effectively prevents hydration and improves the cement particles' capacity for flow retention. The branched chains surrounding the cement particles also play a dual role in steric hindrance and electrostatic repulsion.

Characteristics:

1. High water reduction rate: The excellent dispersion performance provides strong water reduction effect and water reduction rate. The initial water reduction rate is 18%, which ensures the improvement of concrete working performance, concrete strength and cement consumption.

2. Production control: By changing the molecular weight of the main chain, the length of the side chain, the density and type of the side chain group, the water reduction rate, fluidity retention ability and air entrainment performance of this slump-maintaining PCE can be adjusted.

3.Slump Retention Type Polycarboxylate Superplasticizer 50% has long slump retention performance.
