Effect of composite deflocculant on the properties of medium-cement heat-resistant concrete

Comparative analysis is provided for the properties of medium-cement concrete based on mullite filler in relation to different type of deflocculant. The effect of different deflocculants on concrete structure formation, hydration, rheology, strength and heat resistance is discussed. It is proposed that in concrete with a composite deflocculant it is possible to form nano-structures as a result of which there is a considerable increase in concrete strength after drying at 110°C.
