DEMACSA® Solid PCE Superplasticizer Tablets (P-136W / P-172S / P-150) for Concrete

DEMACSA® Solid PCE Superplasticizer is a high-active polycarboxylate-based water reducer in tablet/flake form, developed to address common challenges of liquid superplasticizers—such as low solid content, high transportation cost, and storage difficulty.

After dissolving in water, the product can be formulated into liquid PCE with any required solid content, offering high flexibility, lower logistic cost, and easy handling.

Suitable for a wide range of concrete and mortar applications.

Key Benefits:

Ultra-high active content (≥97%)

Low transport & storage cost compared with liquid PCE

Excellent water reduction & slump retention performance

Good compatibility with various cements, sands, aggregates & mineral admixtures

Green, low-alkali, chloride-free, non-toxic

Enhances pumpability and reduces segregation

Improves mechanical strength after hardening
