Conference Paper Description

This paper investigates the effect of lime stone powder as a partial replacement of sand in cement mortar; on the other hand, this research shows the possibility of using limestone powder as a recycled aggregate. Extensive amount of lime stone powder in our city Mosul, and this can affect the ecological impact of the city, also, the lime stone powder describes as a very cheap material compared with sand. The mix proportion (1:2.75) were adopted and the percentage of the replacement were 40% and 60% as a partial substance of sand with 50*50*50 mm cube iron molds and prisms of 40*40*160 mm were cast and tested for flowability compressive strength and flexural strength. The addition of lime stone powder improves the workability. The compressive strength results fluctuated at age 7 days and 28 days and the increments of lime stone powder improves slightly the flexural strength of the mortar.
