【摘要】 普通矿渣按碱性系数分为碱性矿渣和酸性矿渣。实验室和生产厂试验皆表明，熟料用量减少一半，利用酸性矿渣生产的低熟料水泥，标号不变；利用碱性矿渣生产的低熟料水泥，可提高一级标号。更多还原

【Abstract】 Blast-furnace slag may be divided into basic and acidic ones on tbe bas is of coefficient of basicity. The tests in tbe laboratory and factories show that the strength grade of the cement witk small proportion of clinker, in which it is decreased by 50%,does not reduce in case the active addition is acidic slag and may be raised by one grade with basic slag.更多还原
