Abstract :
The hydration heat evolution process of the cement- fly ash binary system was studied whose water binder ratio(w/b) was 0.35 by using isothermal calorimeter(TAM Air). The fly ash replacement in cement-fly ash binary system was 10%, 30% and 50% respectively. The experiments results indicated that the fly ash makes the exothermic rate and total hydration heat decrease with the mixing replacement. The compressive and flexural strength of cement admixtures was got and the pore in cement admixtures is studied by the mercury intrusion porosimetry.
