摘要
研究了掺加不同功能化学外加剂(减缩剂、早强剂及结晶抑制剂)及30%石灰石粉的普硅水泥砂浆试件在(5±1)℃下,质量分数5%的MgSO4溶液中的外观变化、强度发展及其化学成分分析。结果表明:经侵蚀360 d后,掺加不同功能化学外加剂的各砂浆试件均出现了碳硫硅酸钙晶体,说明实验所用化学外加剂不能从根本上解决TSA问题,但在侵蚀早期(210 d)除结晶抑制剂外均可有效延缓水泥砂浆TSA的发展。
In(5±1) ℃,5% in mass MgSO4 corrosion solution,the visual appearance,strength and composition analysis of cement mortars added with different functional chemical admixtures(shrinkage-reducing agent,hardening accelerator,crystal resistance agent) and limestone powder wereresearched at different storage times.The results indicated that after corroded for 360 days,the thaumasite crystal appeared in all cement mortars added with different functional chemical admixtures.It showed that the functional chemical admi...
