NEXT-Generation Slow Release Polycarboxylate superplasticizer slump retation water reducing agent


Detailed introduction:

NEXT-Generation Water Reducing agent

1. Polycarboxylate superplasticizer water reducing agent

2. Slow release polycarboxylate superplasticizer slump retention water reducing agent

3. Slow release Polycarboxylate superplasticizer slump retention water reducing agent

CL-BT-40 and CL-BT-50 Slow release polycarboxylate superplasticizer slump retention water reducing agents are 2015

 new R&D products by Binzhou Chengli Building Materials CO.,LTD.

The Advantages:

1. New formula,fully reaction, pure appearance

2. Low dosage and high water reducing rato

(40% mother liquid) tested by Shanlv P.O.42.5 ordinary portland cement,with the dosage of 0.4% of CL-BT-40

87g water+1.2g CL-BT-40+300g cement


slump variation retention













CL-BT-40 and CL-BT-50 have the more stronger effect on keeping slump retention than the other slump retention water

reducing agents of china.

If you met the same trouble ,please ask for a sample to test:

Some kinds of cement are terriblly bad . the normal slump water reducing agents may only can effect in 30mins. later the

 cement will lost the pumping ability. but CL-BT-40 and CL-BT-50 can last the pumping time to at least 60mins.

if need the method of making dilution mother liquid ,please send e-mails to the sales.

3.CL-BT-40 and CL-BT-50 Slow release polycarboxylate superplasticizer slump retention water reducing agents can totally

 take place the other water reducing agents

polycarboxylate superplasticizer water reducing agents take 60% market in china,30% market are taken by Aliphatic water

reducing agent.
