This product is a new generation high performance & environmental friendly superplasticizer,
It can be widely used in premix of common concrete, gushing concrete, hydro concrete,
high strength concrete, mass concrete and high quality flow plastic concrete etc.
Special Features:
1 A kind of high performance liquid admixture, low-chloride, low-alkali, nontoxic,
free effect on ecological environment.
2 It has excellent water-reducing ability. can greatly reduce slump loss.
3 It can significantly reduce 25% ~40% mixing water in concrete.
4 High strength enhancing ability. Better performance when used together mineral admixture.
5 No bleeding, anti-segregation, easy to pump and transport.
6 Good appearance of hardened concrete, without water lines, big bubbles, and color difference.
7 A stable performance, non-precipitation.
8 Excellent compatibility with Portland cement.
Uses
1 The dosage of this polycarboxylate superplasticizer for normal strength and high strength concrete is
typically 0.6%~1.2% and 1.2%~1.8% respectively, the recommended dosage for GB8076 standard test is 1.0%.
2 The amount used in concrete will be slightly adjusted depending upon job requirements,
such as concrete strength, variations in cement, aggregate and other job site conditions.
Experiments for appropriate dosage must be carried out when changing concrete mix proportion or materials.
3 It can not be compound with naphthalene and anthracene water reducing admixtures.
Experiment must be done when polycarboxylate superplasticizer is used together with other
chemical admixtures and mineral admixtures.
4 It is not suggested to use directly in concrete or other materials without formulation blending.
The compatibility of this product to particular cement, aggregate and the other raw materials
in the application is not guaranteed.
It should be obtained through trial mixes and formulation technologies by the users.
