In the new millennium of sustainable building, the reuse of Sugar Cane Bagasse Ash (SCBA) as a cement substitute in the production of concrete is gaining appeal. Ash made from sugarcane bagasse is a byproduct of the sugar industry's co-generation unit. Sugarcane bagasse ash is generally dumped in landfill in and around sugar industries leading to environmental degradation. An attempt was made in the present investigation to evaluate the properties of unprocessed sugarcane bagasse ash with silica fume as additive, and quarry dust as fine aggregate in the preparation of concrete and its usage as hollow concrete block. Further, the suitability of these blocks in the construction of masonry structures was also investigated. The characteristics of ingredients such as sugarcane bagasse ash, silica fume, quarry dust, river sand, stone chips and water used in concrete, hollow block, masonry column and masonry prism were studied. The designed mixtures of concrete have been tested for its compressive strength and tensile strength. The experimental data were found to be more than 80% closer to the analytical results. The cost analysis shows that the cost of SCBA silica fume hollow concrete block is 15% higher than the control one. However, in view of sugarcane bagasse ash disposal problems, better strength, and durability than the control specimens this difference would be negligible. The SCBA silica fume concrete can be used in hollow concrete block and as masonry structures to utilize the industrial waste material in large scale, reduce the disposal problems and also improve the performance of masonry structures.
