摘要：

采用正交试验确定水泥熟料最佳组成配比：石灰饱和系数为0.92、硅率为2.5、铝率为1.5；水泥熟料最佳煅烧温度为1 350 ℃。按上述条件，利用工业原料配制水泥熟料，根据其XRD结果可知，矿物组成与吉林亚泰水泥厂的熟料相似。将油页岩灰渣作为混合材，直接掺加到水泥厂熟料中。实验结果表明：随着油页岩灰渣掺量的增加，3 d强度下降明显；但后期补强作用较高，28 d强度较为稳定；在水泥强度满足PC32.5标准的前提下灰渣的最大掺加量以35%～40 %为宜。

Abstract:

The optimum proportion of cement clinker was determined by orthogonal test, displaying as the lime saturated coefficient was 0.92, the silicon rate was 2.5, the aluminum rate was 1.5; the best calcining temperature of cement clinker was 1 350 ℃. According to the above experiment conditions, cement clinker was prepared using industrial material as raw material. The XRD results show that mineral composition of the asprepared cement clinker is similar to the cement clinker in Yatai cement plant of Jilin Province. Oil shale, as the mixing material, is added to cement clinker directly. The relevant experimental results show that with the increasing adding quantity of oil ash, strength decreases significantly in 3 days; but later reinforcing effect is higher. The intensity of 28 days is relatively stable. If cement intensity meets the PC32.5 standards, the maxmium adding quantity of oil ash should be 35% to 40%.
