JST4 is a type of mud-resistant and slow-release polycarboxylate superplasticizer synthesized through a high polymer structure design. Under the condition of high mud content, the superplasticizer can effectively improve the working performance of concrete, and restrain the influence of mud content in sand on the working performance of concrete as well. Mixed with commonly used polycarboxylate superplasticizer types (polyester, polyether) through different proportions, it can prepare concrete without collapse for 2 hours, 3 hours, or longer. It can effectively improve the cohesion and working performance of concrete.
