ZS-HPRA Slump-Retaining Water Reducer
ZS-HPRA Slump-Retaining Water Reducer is a polycarboxylate-based concrete admixture with superior slump retention for 3-4 hours. At a low dosage of 2-12kg per ton of cementitious material, it increases 28-day compressive strength by 22%-35%, reduces cementitious material usage by 8%-18%, and improves durability (impermeability up 30%-45%). Real summer trial data from a commercial batching plant shows 2-hour slump/spread maintained at 220/530mm vs. 150/350mm for conventional products. Backed by 43+ patents and 20 years of R&D from Zhongsen Holding Group.
ZS-PCA High Performance Water Reducer
ZS-PCA High Performance Water Reducer is a customized polycarboxylate-based concrete admixture engineered for high water reduction (20%-30%) and superior slump retention. It increases 28-day compressive strength by 4%-10%, reduces cementitious material usage by 8%-18%, and improves durability (impermeability up 30%-45%). Real trial data from a commercial batching plant shows 2-hour slump/spread maintained at 215/530mm vs. 150/380mm for conventional products, with significantly better initial workability and slump retention. Backed by 43+ patents and 20 years of R&D from Zhongsen Holding Group.
