Reuse of Silica Rich Sugarcane Bagasse Ash in Concrete and Influence of Different Curing on the Performance of Concrete

Sugarcane bagasse ash is used as a pozzolan in concrete. Although studies on sugarcane bagasse ash blended concrete are available, investigation on the influence of different curing methods in the performance of bagasse ash and marble waste blended concrete is essential. Therefore, the present study focuses on the effect of eight types of curing methods on the strength and durability of bagasse ash and marble waste based concrete. Sugarcane bagasse ash (20 %) and marble waste (25 %) were used at their optimum levels as a pozzolan and fine aggregates in concrete. Compressive strength, water permeability, sorptivity and abrasive resistance of concrete for different curing methods were studied. River sand and crusher sand were used as primary fine aggregate. Strength and durability performance of concrete specimens was comparable for moist curing, jute bag curing and straw curing. Normal water curing is found to be beneficial than other curing methods. Water cured bagasse ash and marble waste blended specimens had higher strength (36 %) and lesser permeability (18.8 %) than ambient cured specimens. Although variations in the abrasive wear are observed in the SCBA and MW blended concrete specimens, it is lesser than the permissible limit of 10 mm.
