摘要
水泥水化热随着龄期增加而增加,掺入粉煤灰后各龄期水泥水化热降低,粉煤灰掺量增加与水泥水化热降低幅度不成比例;矿渣粉加入不能明显降低水泥水化热,掺量15%时水泥水化热升高,掺量45%时水泥水化热降低;粉煤灰及矿渣粉复掺相对于纯水泥各个龄期水化热是降低的,但四种复掺配比水化热没有明显规律,在水泥掺量相同时,对水化热降低最明显的是粉煤灰,其次是粉煤灰与矿渣粉复掺,最差为矿渣粉。
The hydration heat of cement increased with increasing age.After adding the fly ash,the hydration heat of cement decreased at each age.The increase of fly ash content was not proportional to the reduction of hydration heat of cement.The addition of slag powder could not significantly reduce the cement hydration heat.The cement hydration heat increased when the slag powder content was 15%,and decreased when the slag powder content was 45%.Each stage hydration heat of cement that added fly ash and slag powder was reduced compared to the hydration heat of pure cement.But there was no obvious rule for the hydration heat of the four kinds of compound cements.When the cement content was the same,the most obvious reduction in hydration heat was fly ash,followed by the blending of fly ash and slag powder,and the worst was slag powder.
