Due to the increasing trend towards high-performance concretes in recent years, cement-based spacers are becoming increasingly important instead of plastic-made ones in buildings. Cement-based concrete spacers with high resistance and durability have been produced, and their performance has been assessed in this study. Fly ash and blast furnace slag have been preferred as aggregate in this study due to their positive contributions to mechanical characteristics and to provide an environmental-friendly production. Seven different mixtures, including the reference mixture, were prepared. Flow diameter and density tests were applied on the freshly prepared mixtures, while unit weight, porosity, compressive strength, and loading tests were performed on the hardened samples. In conclusion, produced concrete spacers have met the requirements of standards, and the best performance in terms of compressive strength has been obtained by using a binary combination of fly ash and blast furnace slag.

由于近年来高性能混凝土的发展趋势，水泥基垫片在建筑物中变得越来越重要，而不是塑料制成的垫片。已经生产出具有高阻力和耐久性的水泥基混凝土隔板，并在本研究中评估了它们的性能。粉煤灰和高炉渣由于它们对机械特性的积极贡献和提供环境友好的生产，因此在本研究中被首选作为骨料。制备了七种不同的混合物，包括参考混合物。对新鲜制备的混合物进行流动直径和密度测试，而对硬化样品进行单位重量、孔隙率、抗压强度和载荷测试。综上所述，生产的混凝土隔板均达到标准要求，采用粉煤灰和高炉渣二元组合，抗压强度性能最佳。
