我国实施新的六大水泥标准后工程建设面临的工作和任务

WORK AND OBLIGATION OF ENGINEERING CONSTRUCTION WITH THE EFFECTIVENESS OF SIX NEW PRINCIPAL STANDARD OF CEMENT IN CHINA

《水泥胶砂强度检验方法》(GB/ T177- 1985) 等同采用ISO679 进行了修订和参考ENV197- 1:1995 欧洲水泥试行标准对《硅酸盐水泥、普通硅酸盐水泥》(GB175- 1992)、《矿渣硅酸盐水泥、火山灰质硅酸盐水泥及粉煤灰硅酸盐水泥》(GB1344- 1992)、《复合硅酸盐水泥》(GB12958-1991) 等六大通用水泥标准的修订,使我国的水泥标准与国际接轨,有利于提高我国工程建设中混凝土结构的质量。各单位应重视这一工作,抓紧学习新标准,积累数据,顺利实现新旧标准的过渡。

After the modification of the standards of Cement,they are in line with international standards,it is beneficial in improving the quality of cement and concrete structure in China in abiding by these standards,it is encouraged to take them as important documents and learn the modified standards quickly,at the same time,to accumulate actual data,to finalize the transition of new and old standards smoothly. The modified standards include Test of Method for Strength of Hydraulic Cement Mortar GB/T 177-85,idt ISO 679:1989;and the six principle cement standard,e.g.Portland Cement and Ordinary Portland Cement,GB175-1992,Portland Blastfurnace-slag Cement,Portland Pozzolana Cement and Portland Fly Ash Cement GB1344-1992,Composite Portland Cement GB 12958-1991,etc.They are modified with reference to European Cement Pre-Standard ENV197-1:1995.
