Study on mildew of polycarboxylic acid water reducing agent

Abstract In practical applications, polycarboxylic acid water-reducing agents are susceptible to microbial contamination and mildew. Through the mold test on the polycarboxylate water-reducing agent with different storage time, the effect of reaction temperature, chain transfer agent type, solid content, compound components and preservatives on the mildew of the polycarboxylate water-reducing agent is studied. The research results can provide technical guidance for long-term storage of polycarboxylic acid superplasticizer and have important application significance.
