This present work is an attempt to use Quarry Dust as partial replacement for Sand in concrete along with the steel fibres. Attempts have been made to study the properties of concrete and to investigate some properties of Quarry Dust reinforced with steel fibres; this article presents the compressive and split tensile strengths of Crimped steel fibre reinforced concrete with Quarry dust. In the experimental work natural Sand was replaced by Quarry dust in the proportion of 50% and 100%. The Crimped steel fibres (CSF) were used in the concrete by 1 and 1.5% volume fraction. After conduction of experiments on the cube and cylinder specimens, the results showed that, the incorporation of Crimped steel fibre reinforced concrete with 50% Quarry dust for M20 grade of concrete increases the mechanical properties of concrete. Keywords: Crimped steel fibre, quarry dust, compressive strength, split tensile strength, slump and compaction factor test.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
