Chemical Admixture PCE Slump Retention Polycarboxylate Ether Superplasticizer as concrete additives
------XRT-DR
Polycarboxylate Ether Superplasticizer Introduction:
XRT-DR is a kind of slump retaining and mud resisting agent for concrete. Under normal circumstances, the combined use of this product with high water reduction type mother liquor can significantly improve the workability and wrapping property of concrete, solve the problem of slump loss of concrete for 2-4 hours, and the serious loss of slump caused by excessive mud and powder content of sand and stone.
Polycarboxylate Ether Superplasticizer Characteristic:
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.
