China Low Dosage Long Durability Slow Release PCE Polycarboxylate

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.
