Abstract: Sugarcane Bagasse Ash is generated as a combustion byproduct from the boilers of the sugar factories. The resulting Bagasse Ash contains higher amounts of Silicon dioxide and Aluminium Trioxide enabling its use as a supplementary cementitious material (SCM) in blended cement systems.The present work is an attempt to understand the behavior of compacted stabilized Lime Bagasse Ash mixtures for the manufacture of Bagasse ash bricks and also to determine the various strength of Masonry Prism. Masonry can be considered as a composite made of two materials. In order to understand the nature of stresses developed in the masonry a masonry prism of three brick height was built according to the codal provisions. Another relevant property of masonry is the bond strength (i.e. flexural and shear bond strengths) between brick and mortar which plays an important role in the masonry structures. Preliminary tests were performed on Cement, Sugarcane Bagasse Ash and M-Sand. In order to arrive at the optimum lime bagasse ash ratio cylindrical specimens of dimension 38mmx76mm were casted by adopting cement to sand ratio of 0.35:0.65. Masonry Prism was built by saturating the Bagasse ash bricks to 75% prior to casting of prisms with 0% and 20% replacement of cement by bagasse ash for 1:6 grade mortar. After 28 days of curing the prisms they were tested in UTM and the compressive strength, flexural strength and shear strength of prism was computed.
