Product Details
Low Dosage Long Durability Slow Release PCE Polycarboxylate
Two types of liquid polycarboxylate superplasticizer water reducing admixtures
1. Polycarboxylate superplasticizer(PCE) water reducing admixture (CL-WR)
2. Slow release polycarboxylate superplasticizer slump retention water reducing agent (CL-SR)
In order to improve workability of concrete, if CL-WR-50 can't reach high slump value, then CL-SR-50 is your best choice.
It mix with CL-WR-50 together.These can keep long time transportation and acheive higher water reducing rate.
Notes: CL-SR-50 can't use alone. Don't mix with sodium naphthalene sulfonate.
