摘要
研究了水泥砂浆在荷载作用下抵抗硫酸盐侵蚀的性能.结果表明,弯曲应力状态下的水泥砂浆在高浓度硫酸盐侵蚀条件下侵蚀速度明显增加,应力水平越高,侵蚀速率越快.试验表明,适当掺入聚丙烯纤维能够有效地缓解硫酸盐对水泥砂浆的腐蚀.
The sulfate attack resistance of cement mortar subjected to flexural load was studied.The results show that flexure load will remarkably increase the attach rate of sulfate solution on cement mortar.The higher the flexural load level,the higher attach rate by sulfate solution.The results also show that adding appropriate amount of PP fiber into the cement mortar will efficiently reduce the attack rate by sulfate solution.
