AN EXPERIMENTAL STUDY ON STRENGTH AND CORROSION OF CONCRETE WITH STEEL SCRAP

Abstract

Steel scrap is a waste product of steel plate manufacturing industry. Every year huge quantity of steel scrap is produced from drilling the steel plates and other related works. Disposing of those steel scrap is a major issues in Oman and all over the world. Landfill is one of the method for disposing the scraps however it produces soil pollution. Also in Oman, there is no waste separation system, therefore all the waste materials are dumped in soil especially in the desert and it is harmful to the environment.  In the present study, steel scrap is added with concrete and the mechanical and physical properties were studied. Three tests were conducted such as slump test to measure the workability of fresh concrete, compressive strength test and corrosion test. In total, four various mixes were prepared with and without steel scrap. The first mix was normal mix without any steel scrap and the remaining three mixes were concrete with adding steel scrap with 1%, 2% and 3%. Based on the compressive strength test results, samples of 1%, 2%, 3% of adding steel scrap shows that the strength was increased for samples with 1% and 2% steel scrap and decreased for 3% steel scrap.
