Superplasticizer
A high-range water reducer that can reduce water demand by 15-30%, allowing very low w/c ratios with high workability.
Modern superplasticizers (PCE — polycarboxylate ether) are essential for high-strength, high-performance, and self-compacting concrete.
For self-compacting concrete (SCC), slump flow measures the spread diameter of fresh concrete after lifting the cone — typically 550-850 mm.
The ratio of the weight of water to the weight of cement in a concrete mix. The single most important factor controlling strength and durability.
A water-reducing admixture that improves workability without adding water, or reduces water demand by 5-12% for the same workability.
Polycarboxylate ether-based superplasticizer — the latest generation, offering up to 40% water reduction and extended slump retention.
