The Research about Polycarboxylate-Based Hardening Accelerating and Water Reducing Admixture

Abstract:

According to the demanded functions, a novel hardening accelerating and water reducing admixture has been excogitated which is based on a polycarboxylate superplasticizer and cooperated with some other hardening accelerants at the same time, and has many merits such as chloride free、sulfate free、low total alkali content、low dosage、high water reducing rate、high early strength and so on. The performance of this admixture has proved to be outstanding especially in accelerating the early strength of 12 hours and 24 hours age in the concrete tests.
