探讨了干拌／蒸气混凝土的水化特性，并以试验结果印证本工艺的可行性．试验工作包括制作１０ｃｍ×１０ｃｍ×１０ｃｍ混凝土试体、进行抗压测试、寻求适当材料配比与最佳压蒸条件；并以水泥与砂浆试体，进行空隙与孔隙率测定、电子显微镜观察、水化程度与氢氧化钙生成量分析，以便了解蒸气水化物的微观结构．抗压测试结果显示，干拌蒸气法只需传统湿拌法水泥用量的一半，即可制得高强度混凝土，每公斤水泥可发挥０．２９４ＭＰａ的混凝土抗压强度．对１０ｃｍ×１０ｃｍ×１０ｃｍ试体而言，最佳压蒸温度与时间分别为１８０～２００℃与２２．５～１８ｈ，其混凝土强度大于６７．２ＭＰａ．微观结构分析显示，干拌／蒸气混凝土之水化程度比常温湿拌２８ｄ龄期者高，孔隙与ＣＨ量少，但水化硅酸钙的生成量却较多．
The hydration characteristics of dry mix/vapor concrete were discussed, and the experimental results were used to confirm the feasibility of the process. The test work includes making concrete specimens of 10cm×10cm×10cm, performing compressive tests, seeking appropriate material ratios and optimum pressure steaming conditions; and testing the voids and voids, electron microscopy observation, and water in cement and mortar samples. Degree of formation and analysis of calcium hydroxide generation in order to understand the microstructure of vapor hydrates. The results of the compression test show that the dry mixing steam method can produce high-strength concrete with only half the amount of conventional wet-mix cement, and can achieve a compressive strength of 0.294 MPa per kilogram of concrete. For 10cm×10cm×10cm specimens, the optimum pressure steaming temperature and time are 180～200°C and 22.5～18h respectively, and the concrete strength is greater than 67.2MPa. The microstructure analysis shows that the hydration degree of dry mix/vapor concrete is higher than that of normal temperature and wet mix 28 d age, but the amount of pores and CH is less, but the production of hydration calcium silicate is more.
