Description
YL-PL-WR is a high performance based on polycarboxylate, specifically developed as effective dispersant, fluidized and high range water reducing concrete agent.
YL-PL-WR is a neutral concentrate grade, it is mainly used as a raw material to produce different types of high performance water reducers for targeted industrial. It complies with ASTM C 494, Type F specifications.
Uses
Advantage
Dosage
0.25– 0.7% by weight of cement. Standard water reduction at normal dosage and significant water reduction at higher dosage. Exact dosage rates are dependent on the type of effect sought, quality of cement and aggregates, water/cement ratio and ambient temperature. Therefore, in many cases it is advisable to carry out trial mixes.
