Dressing of Structural Cracks using Bio Concrete


Microbiology induced cracks remediation technique is a method that has been proved beyond doubt of its efficiency. The review of literature carried out in this area indicates, that the work related to quantification of repair technique in comparison with conversional methods of repair is scarce. The investigation includes two different types of specimens namely cubes and damaged RC beams subjected to high temperature, that are already available. For the cube specimens two different water cement ratios (0.56) with normal, porous (no compaction) and cracked cubes are included. The cracking of cues is done in a pre determined way by inserting a 0.5mm thick aluminum plate to a depth of 75mm top on a 100mm size of concrete cube of m20 grade mix B. sphaericus is used for investigations. The investigation of damaged beams includes three different digress of damages namely, low medium, and high, determined by rebound hammer and Ultrasonic pulse velocity test. The comparison of results of cubes and rehabilitated beams lead to the conclusion, that the bio concrete application is the most effective one the cement mortar is the least effective method.
