摘要
从现场调查资料与区域地质地理特征看,酸性水环境是混凝土建筑物的常见工程环境.由于对酸性水侵蚀作用特征及其机制的认识不足,导致了在国内外的混凝土的标准或规范中,侵蚀性环境水的分类及分类指标存在许多问题,故系统地研究酸性侵蚀作用意义重大.本文主要给出非流动的水动力条件下酸性水侵蚀试验的浸液pH值与时间的关系,以及体系侵蚀反应的平衡分析.
According to our field investigation and regional geologic_geographical feature,acid water solution environment is one of engineering surroundings commonly observed around concrete buildings.Knowledge of acid solution corrosion is seldom and its mechanism is not well known,so that there are many mistakes in the grading and indexes of environment water in national and foreign concrete standards.For this reason,it is important for systematic study of acid corrosion.In this paper ,experiments on acid solution under still hydraulic condition and relation of pH value with time as well as analysis of equilibrium of corroding system are stated.
