A STUDY ON BACTERIAL CONCRETE WITH SUGARCANE FIBERS FLEXURAL BEHAVIOR

This work estimates the flexural behavior of conventional concrete (CC), bacterial concrete (BC), and bacterial concrete incorporated with sugarcane fibers (SBC) and spotlights the role of sugarcane fibers in the bacterial concrete. The bacteria used in this analysis was Bacillus subtitles in liquid form to an optimized value of 1% with a 6 concentration of 10 . The sugarcane fibers with the grain size passing through a 4.75mm sieve in replacement of fine aggregates with an optimized value of 0.1% were used. The beams which were cast using conventional, bacterial, and with sugarcane fibers concrete are total 36 numbers for 28, 56, 84, and 112 days respectively. In those beams, different stirrups spacing is adopted as 130mm, 150mm, and 200mm. The concrete grade used for preparing concrete specimens was M25 and the beams were tested as per IS code 516 – 1999. The load at first crack, cracking behavior, cracking pattern, the pattern of deflections, and load at failure were observed and the values are tabulated. It is observed that the flexural behavior of bacterial concrete incorporated with sugarcane fibers was slightly improved compared to bacterial concrete and conventional concrete.
