other hand, the climate change due to global warming, one of the greatest environmental issues has become a major concern during the last decade. The cement industry is responsible for about 6% of all Co2 emissions, because the production of one ton of Portland cement emits approximately one ton of Co2 into the atmosphere. Many efforts are being made in order to reduce the use of Portland cement in concrete. In this research work, the fine aggregate is replaced by the steel slag, and cement with silica fume and glass powder and natural admixture by 0%,10%,20%,30%,40% in M30 grade concrete. There are many materials like fly ash, furnace slag, foundry sand and silica fume etc.
by the construction industry in the present day. Hence there is a need to identify suitable alternatives to natural river sand as fine aggregate in concrete to cater the future demand of fine aggregate. Steel slag a waste product obtained from steel is identified as a potential replacement to river sand. Steel slag is an industrial by-product of steel industry. It possesses the problem of disposal as waste and is of environmental concern. The results were compared with conventional concrete property can be maintained with advanced natural admixtures such as steel slag powder as partial replacement of cement 0 to 40%. Experiments were conducted to determine the compressive strength; split tensile strength of concrete with various percentages of steel slag aggregate. Two naturally derived gums namely Neem gum (NG) have been tested for their anti-corrosion potential against the steel reinforced in concrete NaCl media at different time interval. Compressive strength, split tensile strength and flexural strength have also been improved on the introduction of gum to the concrete. The inhibitive mechanism of the gums against reinforced steel corrosion in concrete in 3.5% NaCl media has also been proposed.
The paper presents the study of compressive strength and split tensile strength of M30 conventional concrete by replacing the 0% to 40% of steel slag was added, tests were conducted on concrete cubes and cylinder to study compressive and split tensile strengths. The results are compared with the normal mix. Natural gums viz., WG, guar gum, NG, gum Arabic Karroo etc., are used as a viscosityenhancing admixture in various types of concrete structure. Khayat et al., have reported the effect of WG-super plasticizer blends on cement grouts properties were reported the comparative and valuable information of rheological properties of WG and xanthan gum in aqueous media Mbugua er al., reported the influence of gum Arabic karroo on water reducing process concrete mortar. hence, in order to develop gums as affordable natural admixtures with a view to enhance viscosity and improve ant-corrosive concrete structures.
Key words- Concrete, Steel Slag Powder, Compressive Strength, Split tensile strength, Flexural Strength, Neem gum.
1. INTRODUCTION Concrete is one of the most widely used construction materials it is usually associated with Portland cement as the main component for making concrete. The demand for concrete as a construction material is on the increase. On the
