Investigation of the compressive, split tensile and flexural characteristics of steel scrap composite concrete

The research presents the result of an experimental work conducted to investigate the effect of Lathe waste composite concrete (LWCC) on the compressive, split tensile and the flexural strength. Findings show that there was a slight increase in compressive strength of the composite concrete while the increase on the tensile strength of concrete was clearly much on the high side as a result of the addition of steel scrap from lathe waste. The gain in split tensile strength of lathe waste composite concrete after 7 days was between 45.9% 122.4% when compared to the control concrete. An increase of 19.3% 56.6% was recorded on the 14th day as against the same grade of control concrete. Also, a veritable increase, between 44.2% 93.9%, was observed after 28 days when compared to the same grade of controlled concrete.

Omole http://www.iaeme.com/IJCIET/index.asp 895 editor@iaeme.com It was detected that both the compressive strength and the split tensile strength of the composite concrete peaked at a fibre content of 1.5%. The concrete however experienced a minor bust on further increase in fibre content beyond 1.5%. The flexural strength increased up to 1.5% of fibre and on further increase on fibre content reduced the flexural strength of concrete. Steel scrap from lathe waste was found to be an eco-friendly material that can improve the structural strength of concrete.
