提高水玻璃耐酸混凝土(以下简称耐酸混凝土)的抗渗性问题,全国不少科研、生产部门进行过大量试验研究工作,取得了一定的效果。本文就耐酸混凝土抗渗性的外渗剂选择原则进行了初步评述。一、耐酸混凝土抗渗性能的测定方法与评价: 目前我国测定耐酸混凝土抗渗性能的方法有: 第一、压力水渗透法; 第二、pH值与试剂指示法;
Improve the water glass acid-resistant concrete (hereinafter referred to as acid-resistant concrete) impermeability problems, many research and production departments across the country conducted a large number of experimental research and achieved some results. In this paper, the principle of permeability of acid-resistant concrete permeability selection agent were initially commented. First, the acid-resistant concrete impermeability measurement methods and evaluation: At present, China’s determination of impermeability of acid-resistant concrete methods are: First, the pressure of water infiltration; Second, the pH value and reagent instructions;
