Study on the Durability of Concrete in the Northwest Alpine Region

Abstract:

Aiming at the problem of the Alpine, high altitude and other complex environment in the northwest area, and lack of concrete mix and durability data in this harsh environment. Based on the real engineering project, the effect of W/C and the content of cementitious materials on concrete performances were studied, the strength, impermeability and frost resistance of concrete which was mixed respectively two kinds of water reducer and maintained in standard condition and outdoor condition were Studied comparatively. The pore structure of cement paste which was added respectively two kinds of water reducer were also analyzed. The results show that: The self-made polycarboxylate superplasticizer has the effect of low temperature and early strength, and it also can ameliorate the internal pore structure of the sample and improve the impermeability and frost resistance, and improve the durability of concrete.
