上海水泥厂和上海市建筑科学研究所密切配合,突破高标号水泥硅酸三鈣必须大于60％的限制,改变高标号水泥不能掺任何混合材的规定,经过成百次的反复试验,终于试制成功900号高强快硬水泥,并已在工程上试点使用。前后总共试生产500吨左右,用于抢建工程、国防工程、重点工程、代钢材等方面,收到较好的效果。 Shanghai Cement Plant and the Shanghai Institute of Building Science are working closely together to break through the limitation that high-grade cemented tricalcium silicate should be more than 60%, and the requirement that high-grade cement can’t be blended with any admixture should be changed. After hundreds of trials and trials, it is finally trial-produced. The successful No. 900 high-strength, fast-hardening cement has been used in pilot projects. Before and after a total of about 500 tons of trial production for the construction projects, national defense projects, key projects, on behalf of steel and other aspects, received good results.
