In this study, the influence of three mixture variables named Sand/Aggregate ratio, Liquid/Binder ratio, and Paste/Aggregate ratio on the cementitious properties were studied. The durability of cementitious including absorption, absorption rate, resistivity, rapid chloride permeability index, and carbonation rate were examined. Results showed that the alkali-activated slag cementitious has superior durability. The trends of influences on the composites properties for these three mixture variables are similar to those for the ordinary Portland cement concrete. It means that the experiences for making the ordinary Portland cement concrete should be able to be used for the alkali-activated slag cementitious. This paper also provides a lot of data for the alkali-activated slag cementitious for future development of the mix design.
在本研究中，研究了砂/集料比、液/胶凝材料比和浆体/集料比这三个混合变量对胶凝材料性能的影响。考察了胶凝材料的耐久性，包括吸水率、吸水速率、电阻率、快速氯离子渗透指数和碳化速率。结果表明，碱激发矿渣胶凝材料具有优异的耐久性。这三个混合变量对复合材料性能的影响趋势与普通硅酸盐水泥混凝土相似。这意味着制备普通硅酸盐水泥混凝土的经验应该能够用于碱激发矿渣胶凝材料。本文还为碱激发矿渣胶凝材料的配合比设计未来发展提供了大量数据。
