海洋環(huán)境下混凝土耐久性問題分析及解決辦法
|
摘要：本文首先對海洋環(huán)境下混凝土耐久性問題產(chǎn)生的因素進(jìn)行分析，影響其耐久性的因素有：混凝土密實(shí)度不足、空隙過大，氯離子、鎂鹽及硫酸鹽侵蝕，浸析及結(jié)晶作用。針對引起混凝土耐久性問題的因素，列出解決措施，如使用鋼筋阻銹劑，添加混凝土外加劑等。

Analysis and measure on concrete durability in marine environments
Abstract: The factors which influenced the deterioration of conrete in marine environments were analyzed in this paper. The less density, much and big interspace, the corrosion arosed by chlorin ion，magnesium，sulfate ion and crystal are the factors which influence the concrete durability. The answers which can solve the corrosion of concere have been listed, such as stell bar corrosion inhibitor and concrete admixtures are used in concrete.
Keywords: marine environments, concrete, durability, corrosion resistance
