Hydration and mechanical characteris of cement material

Thermal-gravity(TG) method is used to analyze the hydration reaction of cement material.The non-evaporable water content of cement specimens is tested and the hydration degree of cement with different curing time is calculated.The experimental results show that the hydration procedure of cement material will be affected by different water/cement ratio.Moreover,the relationship between hydration procedure and water/cement ratio is theoretically explained based on the chemical kinetics of cement material.Further,the development of compressive strength of cement material with aging consists with the variety of hydration procedure.It illuminates that the direct relationship between microstructure and mechanical property in cement material.
