•Addition of SCBA in concrete needs less water for good workability.•Density of SCBA concrete was found in the range of NWC.•SCBA in NWC shows excellent mechanical & durability properties.•Incorporation of SCBA improves the modulus of elasticity of concrete.•SCBA concrete is suitable for aggressive environment than control mix. Concrete is one of the important material being used in construction industry. Rapid reduction of natural resources, huge amount of energy consumption, and environmental degradation involved in the production of cement has motivated researchers to investigate the suitable alternatives to partially or fully replace the cement. The research performed over the last two decades concerning the use of Sugarcane Bagasse Ash (SCBA) as a cement replacement to produce structural concrete is summarized in this paper. Firstly, general information about SCBA production, effect of burning temperature on the SCBA structure, physical and chemical properties of SCBA and reaction mechanism of SCBA are briefly discussed. Then, the influence of SCBA on the fresh state properties is presented and finally, the hardened state characteristics i.e. strength and rate of strength gain, modulus of elasticity, chloride ion penetration and aggressive environment effect on SCBA concrete are presented.
