新拌混凝土氯离子含量现场检测的现状研究

The Study on the Current Status of On-site Inspection for Content of Chloride Ion in Fresh Concrete

新拌混凝土氯离子含量超标对钢筋混凝土的耐久性危害很大。对新拌混凝土中的氯离子含量进行现场快速检测并完善其检测方法是目前工程界的当务之急。本文阐明了氯离子选择性电极法是新拌混凝土氯离子含量现场检测的重要方法,并提出了仍须解决的几个技术问题。

The excessive chloride ion content of fresh concrete has great harm to the durability of reinforced concrete.It is an urgent task in rapid on-site inspection of chloride ion content in fresh concrete and improve its detection method.This paper expounds that chloride ion selective electrode method is an important method for the on-site inspection of chloride ion content in fresh concrete,and puts forward several technical problems that still need to be solved.
