Abstract
This study combined threeby-productsto fullyreplacecementas cementless blended materialswithout the need for an alkali activator. The feasibility of thecementless materialswasassessed in terms ofworkability, mechanical properties, permeability, and microscopic properties. An innovation cementlessblended materialis consisted ofdesulfurizedgypsum, water-quenched blast-furnace slag,and co-fired fly ash, resulting in a ternary mixture. The resultswere shown to perform well in terms ofcompressive 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 ofgypsum particles by hydrationproducts. Overall, our results confirmthe efficacy of combining 3% gypsum, 60% slag,and 37% fly ash as thecementless compositeswith excellentstrength and permeability.
