摘要
当今世界的建筑工程,仍以钢筋混凝土结构为主体。混凝土的耐久性已成为重大问题。混凝土中钢筋腐蚀是影响耐久性的主要因素,而氯离子又是导致钢筋腐蚀的主要元凶。本文概述氯盐环境与耐久性的关系和对国民经济的影响,并对“全寿命经济分析法”的概念与意义进行阐述。
The global building constructions are mainly with the reinforcing concrete. Concrete durability is a grave question. Rebar corrosion in concrete is mass instance; The chloride is the main factor causing corrosion. The relation between chloride and durability and effect to national economy are presented. The concept and significance of “Life-Cycle Costing Analysis” （LCCA） are expounded.
