Study on the Cement Mortar which is Damaged by Low temperature and Eroded by Carbonate and sulfate
Pages: 3-5
Year: Issue:  9
Journal:  Research & Application of Building Materials

Keyword:  硫酸盐 碳酸盐 侵蚀破坏 材料组分;
Abstract: 研究了不同配合比下掺石灰石粉水泥砂浆在硫酸盐溶液中浸泡1年期间的外观、强度变化。结果表明,水灰比越低,砂浆的抗TSA侵蚀性能越好;不同品种水泥的抗TSA侵蚀能力由高至低依次为:硫铝酸盐水泥>抗硫酸盐水泥>普通硅酸盐水泥;掺硅灰和矿渣细粉均能明显改善混凝土的抗TSA侵蚀性能,且矿渣粉掺量越大其效果越明显。
