复杂环境下矿物掺合料混凝土的耐久性研究
Study on Mineral Admixture Concrete Durability under the Complex Environment
摘要
Abstract
Using fly ash, slag, diatomite and zeolite as mineral admixtures, by designing orthogonal test with types and dosages of mineral admixtures for concrete improvement, to study the concrete durability adding various different active mineral admixtures under the complex conditions of chloride, sulfate and freeze-thaw erosion, to get the types and dosages of mineral admixtures of the best durability concrete by analyze of experimental results, with the aid of analysis methods such as X-ray diffraction and scanning electron microscope, study micro-mechanism of concrete improvement mixing mineral admixtures. The research results show that the mineral admixtures can restrict the formation of Thaumasite and improving the concrete pore structure, in order to improve evidently the concrete durabilyty, and diatomite is the best mineral admixture among them.关键词
