how to know the usage density of early strength water reducing agent
the side chains of early-strength superplasticizers have an important impact on the dispersion and dispersion retention of cement particles. the smaller the degree of polymerization of the side chains, the greater the fluidity loss of the cement slurry. fast. due to the steric hindrance effect, the synthesized high-efficiency water-reducing agent with polyoxyethylene side chains increases…
