This research presents a study of the compressive strength of mortar in ternary blend materials system of silica fume (SF) and ground ceramic electrical insulator (CE). The mortar mix proportions with constant 10% of SF as a partial cement replacement was used. Then, the use of CE in amounts of 5, 10, 15, and 20% mixed with SF as a partial replacement of cement by weight of the cementitious material. Water to binder ratio (W/B) with constant of 0.50 was used. Superplasticizer (SP) was used to improve the workability of mortar. Test results found that the use of CE in amounts of 5, 10, 15, and 20% mixed with SF as a partial replacement of cement by weight of the cementitious material resulted in higher compressive strength when compared to control mortar (CT), as well as mortar mixed with SF in amounts of 10% by weight of the cementitious material. The ground ceramic electrical insulator can be used as a cementitious material. The results of this research are a reduction in the amount of waste materials, reduce the burden of disposal and reduce environmental problems.
