Effect of Steel Slag and Bagasse Ash on Strength of Concrete

Abstract

An experimental investigation was carried out to evaluate the strength properties of concrete. The concrete mix of M-50 grade was designed and produced by replacing steel slag partially with fine aggregate and bagasse ash partially with cement. The mix proportions were prepared with varying percentage of bagasse ash including one control mix of steel slag. Bagasse ash in concrete was replaced with 0, to 20% with an interval of 5% with cement by weight and one concrete mixture that contained 10% steel slag was considered as the control mix. Various strengths considered for investigations are compressive, flexural and split tensile. Cube of size 150 mmï‚´150 mmï‚´150 mm for compressive strength; beams of size 500 mmï‚´100 mmï‚´100 mm for flexural strength and cylinders of size 300 mm in depth ï‚´ 150 mm diameter for split tensile strength were cast. All the specimen were water cured up to 7 and 28 days and tested subsequently. Relations between compressive strength with all other strengths are developed. A comparison of result of modified steel slag concrete with that of normal concrete, showed significant improvement in the result of various strengths.
