•Review of studies pertaining to use of dimensional stone waste in mortar mixes.•Dimensional stone waste as fine aggregate in mortar improve strength and durability.•At higher substitution level dimensional stone waste as fine aggregate increase water demand and shrinkage characteristics. Dimensional stones are natural rocks that exhibit distinctive texture, vibrant colour and unique patterns. They are hard and durable, and, hence can be easily shaped into various shape and sizes; to be used as floor and cladding decorative purpose. Mining of these stones is highly unsustainable process producing tons of solid and slurry waste which pollutes the local environment. Studies are available where this discarded waste is used as a substitution of conventional construction and building material. The present review paper explores the effect of dimensional stone waste on workability, strength and durability properties when used as partial to full replacement in variety of mortar mixes. Reviews of studies suggest that the discarded waste improve compressive and tensile strength, enhances the durability characteristics and bond properties of mortar. However, the inclusion of this waste also increases the overall water demand to achieve the desired workability. The review of literature also highlights the shortcoming in the available literature and possible scope of research which are required in order to establish the use of dimensional stone waste as a construction material for mortar.
