Synthesis and preparation of concrete tackifier and investigation of its properties
Concrete tackifiers were synthesized by free radical polymerization,the optimal synthesis process of tackifiers was investigated,and the performance of concrete tackifiers with different carboxyl group densities was tested.The experimental results show that the higher the carboxyl group density,the higher the adsorption capacity of the polymer on the cement particles,but the polymer with too high adsorption capacity will compete with the polycarboxylic acid water reducing agent to adsorb,reducing the flow of the cement paste.Based on the optimal process of the preparation of the NC-ZN420 viscosity builder can effectively reduce the amount of water secretion of the concrete,increase the viscosity of the concrete,viscosity of the concrete,viscosity builder used in the development of the strength of concrete does not have a significant effect.
