摘要
通过一系列试验系统研究了重晶石粉的掺入对水泥砂浆凝结时间、强度和密度的影响。结果表明,重晶石粉为非活性混合材,其对水泥强度无增进作用,最适宜掺量为20%;重晶石粉掺量在30%以下时掺入对水泥的凝结时间几乎没有影响。
The effect of barite on setting time, strength and proportion of cement mortar was studied through a series of tests. The results showed that barite was non-active admixture, it couldn＇t improve the strength of cement and its optimum content was 20%. There would be little impact on the setting time of cement if the content of barite powder within 30%.
