【摘要】 商品混凝土抗碳化性能是影响混凝土耐久性的一个重要方面。商品混凝土的配制技术、养护条件及其所处的服役环境是影响商品混凝土抗碳化性能的3个主要因素。本文首先简要阐述了混凝土碳化的机理及腐蚀破坏;然后详细介绍了影响商品混凝土抗碳化性能的3个主要因素的研究进展。为了保证商品混凝土的抗碳化性能,必须根据混凝土结构物所处的服役环境及适合的配制技术来设计商品混凝土,并采用与之相配套的施工养护条件。更多还原

【Abstract】 Carbonation resistance of ready-mixed concrete is one of the important fields in the durability of concrete.The preparation techniques,curing condition and service environment of ready-mixed concrete are the three main factors influencing the carbonation resistance of ready-mixed concrete.The mechanism and corrosion of carbonation of concrete were illuminated firstly in this paper.Then a review of the three main factors influencing the carbonation resistance of ready-mixed concrete was presented in detail.In order to ensure the carbonation resistance of ready-mixed concrete,we should design the ready-mixed concrete according to the special service environment and preparation techniques of concrete and adopt a corresponding curing condition.更多还原
