Impact of Jute Fibre, Sugarcane Bagasse Ash and Nano Alumina on Mechanical Properties of Concrete

Abstract

To date, numerous investigations have been conducted on supplementary cementitious materials (SCM'S) to enhance the properties of concrete. These SCM’S not only decreased cement and aggregate consumption but also lowered the environment issues. This research conducted the study on the ternary combination of sugarcane bagasse Ash (SCBA), Jute Fibre (JF) and Nano alumina. The focus of the current study is to investigate the mechanical properties of concrete on replacing cement with different percentages of bagasse ash (0, 5, 10, 15 and 20%). Jute Fibre proportions were utilized as 0.15, 0.25, 0.35 and 0.45% for partial replacement of cement at optimum dosage of bagasse ash (BA). Compressive strength [CS], [STS] Split tensile strength, and [FS] flexural strength of the hardened composites were examined. To investigate the further improvement in strength properties of concrete, Nano Al2O3 percentages of 0.75, 1.75 and 2.75% were incorporated into the Mix by volume of mortar. A water-cement ratio (0.4) was held constant. The findings showed that 1.75% Nano alumina based concrete with 10% Bagasse Ash and 0.25% Jute Fibre outperforms all other concretes in terms of strength characteristics.
