关于高性能混凝土中性化及其防控措施

高性能混凝土用于严酷的环境中,最重要的是要有较好的长期性能和耐久性。混凝土中性化会严重影响结构、构件的承载能力及耐久性,大大降低使用寿命。本文通过分析高性能混凝土的特点及其中性化的原理,提出在构件施工及养护过程中可采用的防控措施。

Study about the Neutralization of High Performance Concrete and Its Precautionary Measurements

Since the high performance concrete is used in harsh environment , it is most important for it to have better long -term perform-ance and durability .The neutralization of concrete may seriously affect the bearing capacity and durability of the structure , and then greatly reduce its service life .This paper analyzes the characteristics of high performance concrete and principle of its neutralization , and gives the prevention and control measures which can be taken during the construction and maintenance process of the structure .
