Aiming to solve the decrease of the mechanical strength of calcium aluminate cement (CAC) at high temperature, nano-γAl2O3 additive ranging from 0.5 to 1.5 mass% was added in CAC with water to cement ratio (w/c) of 0.36 respectively. The influence of nano-γAl2O3 additive on hydration heat was studied by isothermal calorimetry. It shows that nano-γAl2O3 additive increases heat release rate and shortens...
