摘要
碳硫硅钙石型硫酸盐侵蚀(TSA)是一种特殊的硫酸盐侵蚀形式,直接导致混凝土中C-S-H凝胶的分解,使混凝土变成一种灰白色、果肉状泥砂混合物。介绍了CO2、温度、pH值、C3A、C-S-H、水泥品种和粉煤灰等影响因素的研究情况,结合研究情况提出一些建议。
The thaumasite form of sulfate attack is a special kind of sulfate attack,the form of attack lesds to decomposition of C-S-H gel. As a result,the attacked concrete becomes a white mushy mixture. The research on influence factor such as CO2、temperature、pH、C3A、C-S-H、cement type and fly ash is expatiated. And some advice is put forward with present research.
