Abstract

This research presents a study of the compressive strength, porosity and water absorption of mortar with ternary blend cementitious system of ordinary Portland cement (OPC), silica fume (SF) and ground basalt rubble (BD). In this research, SF was used to replace OPC at a constant rate of 10% by weight of binder. Additionally, a consistent 10% rate of SF was mixed with BD at rates of 10, 15, 20, 25, and 30% by weight of binder. Water to binder ratio (W/B) with constant of 0.45 was used. Superplasticizer (SP) was used to improve the workability of mortar. Test results showed that using SF at 10% mixed with BD at rates of 10, 15, and 20% by weight of binder results in greater compressive strength, reduced porosity, and water absorption as compared to control mortar (CT).The ground basalt rubble can be developed as a new cementitious material in construction work. This study's findings can result in a reduction in both the amount of waste materials produced and the disposal burden.
