Abstract:Limestone quarry dusts are fine materials obtained during the process of crushing rock to produce gravel. The effects of dust content in crushed limestone sand on the properties of fresh and hardened self-compacting mortar are not well known. An experimental study was undertaken to find out the effect limestone dust content on the properties of fresh and hardened self-compacting mortar (SCM). SCM mixtures were prepared using crushed limestone sand partially replaced with limestone dust at varying percentages (0, 5, 10, 15, 20, 25 and 30%). Tests used to characterize the properties of mortars include: slump flow, flow time, viscosity measurements, compressive strength and flexural strength at 3 and 28 days of age. Results indicate that the crushed limestone dust significantly improves the rheological and mechanical properties of SCM with a content ranging from 10 to 15% of limestone dust.
