1 引言水工建筑物多以混凝土结构组成,而这些混凝土结构多处在气候恶劣的环境中,受泥沙、水流、物理、化学、气温等影响因素颇多。混凝土的碳化是导致混凝土结构破坏的主要因素之一,由于碳化,致使水工建筑物的运行寿命大为缩短,给国家造成了极大浪费。所以有必要进一步探讨水工建筑物混凝土的碳化机理及防治措施。本文以白沙水库部分水工建筑物的碳化处理为例,来探索混凝土碳化的规律。
1 Introduction Hydraulic structures are mostly composed of concrete structures, and many of these concrete structures in harsh environments, influenced by sediment, water, physical, chemical, temperature and other factors. Carbonation of concrete is one of the main factors leading to the destruction of concrete structure. Due to carbonization, the operational life of hydraulic structures is greatly shortened, causing great waste to the country. Therefore, it is necessary to further investigate the carbonation mechanism and prevention and cure measures of concrete in hydraulic structures. In this paper, a part of Baisha reservoir hydraulic structure of carbonation as an example to explore the law of carbonation of concrete.
