不同掺量配比对复合硅酸盐水泥性能的影响

研究了粉煤灰、粒化高炉矿渣及石灰石的不同掺量对复合硅酸盐水泥的凝结时间及抗压强度的影响。结果表明：石灰石粉对水泥的负面影响较大,粉煤灰掺量增加有缓凝及削弱水泥早期强度的作用,而增加高炉矿渣掺量具有缓凝和提高水泥后期强度的效果。

Impacts of different mixing rate on composite portland cement property

This paper studies the impacts of different mixing quantity of fly ash,BF slag granulation,and limestone on the setting and hardening time and compressive strength of the composite portland cement.Results show that limestone has great negative effect on the cement,adding fly ash mixing quantity can retard or weaken the early cement strength,while adding BF slag granulation can retard and improve the post cement strength.
