Microstructure Analysis of the Influence of Composite Polymers on Concrete Mechanical Performance

Based on the research of various kinds of composite polymers of redispersible latex powder, cellulose ether, organic silicon water repellent and so on , with additions of polymers and the additive of mineral powder-silica fume composite minerals, the paper studies on the influence of composite polymer mainly made of materials on concrete mechanical performance and microstructure. With the addition of composite polymers, despite that the early hydration reaction is delayed, the hydration reaction of 28d speeds up evidently and its internal structure becomes tighter, which is beneficial for the improvement of concrete persistence.
