Abstract

In this experiment, based on the traditional production process of polycarboxylate superplasticizer, 4-hydroxybutyl vinyl ether modified polycarboxylate superplasticizer was used to prepare mud-resistant polycarboxylate superplasticizer ZNJ1. The effects of ZNJ-1 and polycarboxylic acid superplasticizer on the on the changes of slump, fluidity and Emptying time after 1 h of concrete mixed with manufactured sand and washed manufactured sand were studied. The experimental results show that the use of 4-hydroxybutyl vinyl ether modified polycarboxylate superplasticizer significantly improves the adverse effects of mud powder in manufactured sand.
