Third-generation PCE superplasticizer in 50%, 55% and 60% solid grades. Higher strength, longer slump retention and lower concrete cost — manufactured and tested in-house, shipped worldwide.
PCE superplasticizer is the third generation of concrete water-reducing agents — evolved from lignosulfonate and naphthalene types. It disperses cement particles more effectively, so you use less water and less cement without giving up workability.
Lower water-cement ratio means higher compressive strength and denser concrete — typical results reach 32–36% water reduction on P.O 42.5 cement.
SR grades hold fluidity past 180 minutes — tested 230–280 mm after 60–120 min — for long hauls, hot weather and congested job sites.
ES grades speed up formwork cycling and precast output with 3-day compressive strength ratios up to 215% of reference on early-strength types.
Chloride content at 0.0007% and low total alkali keep steel safe — suited to marine, reinforced and prestressed concrete.
Recommended dosage is only 0.23–0.55% of binder weight. A little goes a long way — each drum covers far more concrete than conventional admixtures.
Water-reducing, slump-retention and early-strength grades — each in 50/55/60% solids. Blend them to hit your exact slump, strength and cost targets.
Every grade is a colorless-to-yellowish viscous liquid, ISO-certified and batch-tested in our own lab. Choose by your priority: water reduction, slump retention or early strength.
High water reduction
Maximum water-cement reduction for high-strength and standard mixes. Tested water reduction 32–36%.
Long slump retention
Keeps concrete workable 3+ hours — ideal for long-distance hauling and hot-weather placement. Often blended with WR grades.
High early strength
Accelerates strength gain for fast formwork turnover and precast production without sacrificing fluidity.

Use WR (water-reducing) for standard and high-strength mixes, SR (slump-retention) for long hauls and hot weather, and ES (early-strength) for precast or fast formwork cycling. SR grades are often blended with WR grades — our technical team can recommend the right combination and dosage for your materials.
Typically 0.23–0.55% of binder (cement) weight depending on the grade, target slump and materials. Always run a compatibility and dosage trial with your own cement and aggregates; our lab can support the mix design.
