In this paper the strength behavior of Bacillus Bacteria and strengthening characteristic of GFRP sheets are investigated. In this study the optimum percentage of Bacillus Bacteria is find out from the compressive strength test. The cubes are casted based on the percentage replacement of Bacillus Bacteria in cement. The replacement of Bacillus Bacteria in cement is 0%, 10%, 20%, 30% 40%, 50%. Totally 18 cubes are casted out of this 3 cubes for each percentage. After 28 days the compressive strength was find out from the cubes. From the compressive strength test the optimum percentage of Bacillus Bacteria is concluded as 20%. Based on these result columns are casted. Totally 12 columns are casted out of these columns 6 columns are conventional and 6 columns are Bacillus Bacteria replace columns. The axial compressive strength test was carried on 3 conventional and 3 Bacillus Bacteria replaced column to find out the ultimate load carrying capacity. From this ultimate load 70% of load is given to the remaining columns as a preloading. After given the preloading these columns are strengthened by using GFRP sheets. The strengthened columns are tested under axial compression test. From this result the ultimate load carrying capacity, deflection, stiffness, and energy absorption of column is calculated.
