Chemical Admixture PCE Slump Retention Polycarboxylate Ether Superplasticizer as concrete additives
------XRT-DR
Polycarboxylate Ether Superplasticizer Introduction:
XRT-DR serves as a specialized admixture for concrete, functioning as both a slump retention and clay resistance agent. Typically, when this product is used in conjunction with high-range water-reducing masterbatch, it can remarkably enhance the workability and cohesion of concrete. It effectively addresses the issue of slump loss over a period of 2 to 4 hours. Moreover, it mitigates significant slump degradation caused by the excessive amount of clay and fines in aggregates, ensuring the consistent quality of concrete mixtures.
Polycarboxylate Ether Superplasticizer Characteristics:
1.No initial water reduction, does not increase the initial expansion and slump of concrete;
2.The water reduction performance is gradually produced after 1 hour, and the slump of concrete will increase with time by
increasing the amount of slump retention and mud resistance agent;
3. with resistance to clay/stone powder and temperature caused by slump loss problems;
4. The use of this product can be appropriate to reduce the amount of water reducer.

Noted:The test results show that when XRT-DR is used in combination with PCE B, the initial fluidity of concrete is slightly
small, and the cohesion is basically not affected the inner concrete has good expansibility and slump retention, and the strength development meets the standard requirements.
Recommended parameters:
The dosage of total cementing material was 0.05-0.20%.
