1982年11月~1984年2月,我公司为适应工程施工的需要,大量采用了三 F 早强减水剂。效果显著,特别是冬季施工,效果更为明显。先后在百余个单位工程的六万余米~3混凝土中,掺用三 F 型早强减水剂达二百三十余吨。使用水泥品种有上海矿渣325~#、425~#、普通425~#、525~#,金山矿渣425~#、普通525~#,浙江江山普通425~#、525~#,平湖普425~#,无锡普425~#,湖州普425~#,宁国胜利
From November 1982 to February 1984, our company adopted a large number of early-strength water-reducing agents for the purpose of engineering construction. The effect is remarkable, especially in winter construction, the effect is more obvious. In the more than 100 units of the project of more than 60,000 meters ~ 3 concrete, the use of three F type early strength water reducing agent of more than 230 tons. The types of cement used are Shanghai slag 325~#, 425~#, ordinary 425~#, 525~#, Jinshan slag 425~#, ordinary 525~#, Zhejiang Jiangshan ordinary 425~#, 525~#, Pinghu Pu 425~# , Wuxi Pu 425~#, Huzhou Pu 425~#, Ningguo Shengli
