1 我国水泥检验方法标准与产品标准发展概述 解放初期,根据当时条件,以日本软练法为基础,制订了我国历史第一个统一的水泥标准。1956年又采取了以苏联硬练法为蓝本的我国三大水泥标准,“硬练法”造成水泥标准的严重虚似现象。从1979年以后,我国采用现行GB 177软练法,在很大程度上解决了同标号普通水泥与矿渣水泥在砼中使用效果的差别,但并没有根本消除两者之间的差别。
1 Overview of China’s Cement Inspection Method Standards and Product Standards Development During the initial period of liberation, based on the prevailing conditions, Japan’s soft-learning method was used to formulate the first uniform cement standard in China’s history. In 1956, it adopted the China’s three major cement standards based on the Soviet Union’s hard training method. The “hard training method” caused a serious virtual phenomenon of cement standards. After 1979, China adopted the current GB 177 soft-learning method, which largely solved the difference in the use effect of the same grade of ordinary cement and slag cement in the concrete, but did not completely eliminate the difference between the two.
