Abstract

This study combined three by-products to fully replace cement as cementless blended materials without the need for an alkali activator. The feasibility of the cementless materials was assessed in terms of workability, mechanical properties, permeability, and microscopic properties. An innovation cementless blended material is consisted of desulfurized gypsum, water-quenched blast-furnace slag, and co-fired fly ash, resulting in a ternary mixture. The results were shown to perform well in terms of compressive strength, absorption, and chloride ion penetration. Scanning electron microscopic micrographs revealed that desulfurized gypsum accelerated hardening and improved the compressive strength through the formation of C-S-H and C-A-S-H gels produced by Ca(OH)2, SiO2, and Al2O3. The improvements in permeability can be attributed to the coating of gypsum particles by hydration products. Overall, our results confirm the efficacy of combining 3% gypsum, 60% slag, and 37% fly ash as the cementless composites with excellent strength and permeability.
三元无水泥共混材料的工程性能
这项研究结合了三种副产品,在不需要碱性激发剂的情况下,完全取代水泥作为无水泥混合材料。从工作性、机械性能、渗透性和微观性能方面评估了非水泥材料的可行性。一种创新的无水泥混合材料由脱硫石膏、水淬高炉矿渣和共烧飞灰组成,形成三元混合物。结果表明,在抗压强度、吸收和氯离子渗透方面表现良好。扫描电子显微镜显微照片显示,脱硫石膏通过形成由Ca(OH)2、SiO2和Al2O3产生的C-S-H和C-A-S-H凝胶来加速硬化并提高抗压强度。渗透性的改善可归因于水化产物对石膏颗粒的包覆。总的来说,我们的结果证实了将3%的石膏、60%的矿渣和37%的粉煤灰结合作为具有优异强度和渗透性的无水泥基复合材料的有效性。
