Description for polycarboxylate superplasticizer PCE:
HS301 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 for PCE:
1 PCE is a kind of high performance liquid admixture, low-chloride, low-alkali, non-toxic, free effect on ecological environment.
2 HS301 has excellent water-reducing ability. can greatly reduce slump loss.
3 HS301 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 PCE with good appearance of hardened concrete, without water lines, big bubbles, and color difference.
7 High durability, HS301 polycarboxylate superplasticizer can greatly improve compactness, freeze-thaw resistance, carbonation resistance, elastic modulus and impermeability; reduce drying shrinkage and creep of concrete.
8 A stable performance, non-precipitation.
9 Excellent compatibility with Portland cement.
Uses for polycarboxylate superplasticizer PCE:
1 The dosage of HS301 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 of HS301 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 HS301 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 s ested to use HS301 products directly in concrete or other materials without formulation blending. The compatibility of HS301 products 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.
