摘要
混凝土是一种由砂石骨料、水泥、水等混合而形成的非均质脆性材料。受混凝土施工和本身变形、约束等一系列问题的影响,硬化成型的混凝土中存在众多的微孔隙、气穴和微裂缝,通常会使内部的钢筋等材料产生腐蚀,降低混凝土的承载能力、耐久性及抗渗能力,影响建筑物的结构和外观以及使用寿命。
Concrete is a stone aggregate, cement, water, etc. to form a mixture of non - homogeneous brittle materials. By the concrete construction and its deformation, bound by a range of issues such as the impact of hardening of the concrete forming the existence of a large number of micro - pores, cracks and micro - cavitation, usually within reinforced will produce materials such as corrosion, reduce the carrying capacity of concrete, durability and impervious to influence the structure and appearance of buildings, as well as life.
