Reflections on the Detection Method of Polycarboxylate Superplasticizer

Abstract:

According to the detection method of "Polycarboxylates high performance water reducing admixture"(JG/T223-2007), the different concrete mix ratio with different binder systems were designed to test the air-entraining content and compressive strength ratio for 3days of the HSP-V and PCA-II polycarboxylate superplasticizer. The results show that the mineral admixtures can reduce the air-entraining content of the HSP-V and PCA-II polycarboxylate superplasticizer, and lead to the compressive strength ratio for 3 days improved. Therefore mineral admixture on polycarboxylate superplasticizer should be fully considered, in order to adapt to the needs of the practical engineering.
