Polycarboxylate superplasticizer chemical additives for concrete
Polycarboxylate superplasticizer chemical additives is a new generation of high performance superplasticizer developed by Qingdao Hongsha polymer materials Co. Ltd..With this product, concrete has high slump retention,slumps keep unchanged within 30min andloss little in 1h; Meanwhile, it has advantages such as low dosage,high water reducing rate and low shrink rate. It improves the liquidity of concrete greatly with this product,makes the concrete keep long time construction performance,as well as ameliorates its peaceability and physics performance,improving construction quality.
The technical performance of Polycarboxylate superplasticizer chemical additives as follows:
