Study of Steel Scrap Reinforced Concrete with Partial Replacement ofCement with Bagasse Ash

Abstract

According to the report published by United Nations Food and Agricultural Organization in 2017, it is estimated that India presently produces 341.2 million metric tonnes of sugarcane, proving the fact that India is the second largest sugarcane producer on the globe. Sugarcane bagasse is a fibrous waste product recovered from the Sugar milling industry. There is an increasing threat of disposing the bagasse ash, as it causes serious environmental hazards. Hence, there is an immediate need to find an alternative solution to use the waste product in the form of bagasse ash, in an effective manner. Thus, this paper dealt with the replacement of cement using the bash in concrete. Furthermore, there has been numerous research made, into using steel fibre in concrete. Similar to steel fibre is steel scrap, which is a waste material from Lathe machines. Thereby, this paper will also deal with addition of steel scrap to the concrete, as the latter is much cheaper than steel fibres, which are normally used. Hence, a comprehensive study is made in the research, where concrete is prepared by partially replacing cement by bagasse ash and adding steel scrap to the volume of concrete, as a whole. Here, cement is partially replaced by bagasse ash by 0%, 5%, 10% and 15% by weight of cement in concrete. Similarly, steel scrap is added at dosage of 0%, 1% and 2% to the volume of concrete. The studies were conducted on 12 different combinations of bagasse ash and steel scrap being used in M20 grade of concrete. The parameters studied include compressive strength, split tensile strength and flexural strength of concrete. The results are compared with conventional concrete and, the optimum combination of using both bagasse ash as a partial replacement material for cement and addition of steel scrap to the concrete, is determined.
