摘要
混凝土在使用期间,会由于环境中的水、气体及其中所含侵蚀性介质的渗入,产生物理和化学反应而逐渐劣化,混凝土抵抗这种劣化作用的能力就是耐久性。现在,高强高性能混凝土在结构工程的许多领域得到了越来越多的应用,特别是用于严酷环境中的有特殊要求的结构,这就要求高强高性能混凝土具有较好的长期性能和耐久性。在不同的环境中,起主导作用的因素不同,混凝土的劣化会有不同的表现。本课题研究了超高强高性能混凝土的抗氯离子渗透性。
During use of concrete, due to the water, gas in the environment and contained aggressive media are infiltrated, resulting physical and chemical reactions,thus the concrete is gradually deteriorated, the ability of concrete to resist such degradation effect is durability. Now, the high strength and high performance concrete is becoming more and more popular in many areas of structural engineering applications, Especially for harsh environments and have special requirements of structure, it requires that high strength high performance concrete must have good long-term performance and durability. In the different environment, the factors which can play a leading role will be different, The deterioration of concrete will have different performance, so this topic is aimed at researching Anti-chloride ion permeability of ultra-high strength and performance concrete.
