PREMIXING OF Bacillus subtilis IN CONCRETE TO SELF HEAL THE MICRO CRACKS AND ENHANCE ITS COMPRESSIVE STRENGTH
The present invention generally relates to a method for preparation of a self healing concrete that also enhances the compressive strength. The method comprises culturing a bacterial strain in a nutrient medium to get a bacterial culture, mixing the bacterial culture into a liquid medium to get a bacterial medium. The method further comprises mixing cement, natural sand, a coarse aggregate and water to get a concrete mixture, which is then mixed with the bacterial medium and calcium lactate to get a self-healing concrete mixture. The method further comprises setting the self-healing concrete mixture for a predetermined amount of time to get a self-healing concrete and later micro-cracks were induced in it. Lastly, the method further comprises curing the self-healing concrete that results in automatic repair of one or more cracks and helps in maintaining the integrity, strength and durability of the self-healing concrete. 00( j .1R EM E t E aa 0 fl w 220 o c o2 W ~ 2- 2 -o= - E i -. td 13 ' fa --- t T l m -0 '0 t; 0 aj w M E -0 tJ 1 0- aflj t e 2j C -I--
