耐用的混凝土是在暴露于其环境时保持其原始形式,质量和可维护性的混凝土。
The fundamental factor in creating durable concrete is the use of pozzolans and ground granulated blast-furnace slag (GGBFS) and chemical admixtures in combination with portland cement, and the proper selection of aggregate (proportion, hardness, grading, shape,尺寸和相位组成)。最大化混凝土的概率最大化的最佳方法是耐用的
产生混凝土,将为所需的使用寿命提供所需的服务
将放置和使用它的环境。
每种混凝土混合物应按照暴露条件,建设考虑和结构标准成比例。暴露在冷冻和解冻,硫酸盐,除冰化学品,酸,
varying moisture conditions, and abrasive loadings should all be considered when selecting materials and proportions.In addition, available materials must be selected to prevent excessive expansion due to alkali-silica reaction (ASR), alkali-carbonate rock reaction, and thermal gradients.
