本文提出了一种基于固态反应的机理。借此,水泥浆体液相中的离子被水泥矿物晶体表面的离子化学吸附,并扩散进晶体生成了引起水泥浆体凝固和硬化的反应产物。再烧熟料和CaCl_2溶液的混合物经摇晃搅拌两分钟后,进行过滤并分析其中SO_3、Cl_2、CaO、K_2O和Na_2O的含量。研究了由熟料与氯化钙溶液混合而成的熟料浆体发生固态反应的依据。每隔1分钟、5分钟、15分钟和30分钟对浆体进行过滤,并对其中的Cl_2加以分析。结果表明:波特兰水泥中铝酸钙和硅酸钙的主要部分不进入溶液与水及硫酸钙反应。
This article proposes a mechanism based on solid-state reactions. In this way, ions in the liquid phase of the cement paste are chemically adsorbed by the ions on the surface of the cement mineral crystals, and diffuse into the crystals to generate reaction products that cause the solidification and hardening of the cement paste. The mixture of re-sintered clinker and CaCl 2 solution was shaken and stirred for two minutes, followed by filtration and analysis of the contents of SO 3, Cl 2, CaO, K 2 O, and Na 2 O. The basis of the solid-state reaction of clinker slurry mixed with clinker and calcium chloride solution was studied. The slurry was filtered every 1 minute, 5 minutes, 15 minutes, and 30 minutes, and the Cl2 therein was analyzed. The results show that the main components of calcium aluminate and calcium silicate in Portland cement do not enter the solution and react with water and calcium sulfate.
