Self Healing Concrete or Bacterial Concrete

Kaushik Bokarde

Abstract: Cementitious hollow tubes were made by extrusion and used as healing agent containers that were embedded within the mortar matrix to get self-healing properties. Natural materials area unit remarkably economical as a result of they fulfill the advanced needs posed by the biological functions and that they do thus mistreatment as very little material as potential. Most natural materials area unit advanced composites whose mechanical properties area unit typically outstanding, considering the weak constituents from that they're assembled. Moreover, most natural materials area unit property, utile and, once disposal is important, perishable, creating them a model for environmentally acutely aware engineering. These advanced structures, that have up from many millions years of evolution, area unit inspiring Materials Scientists within the style of novel materials. Most living tissues or organisms will heal themselves, provided the incurred harm is moderate. Most designed materials area unit developed on the premise of the harm interference paradigm and deteriorate with time irreversibly, that limits the lifetime of varied parts and generally causes ruinous harm. it'd be then terribly fascinating to implement the power of self-healing in inorganic materials. thus there was a demand to develop Associate in Nursing intrinsic bio-material, a self-repairing technique which might rectify the cracks and fissures developed in concrete. Bio-concrete may be a material which might with success rectify cracks in concrete. this system is very fascinating as a result of the activity of crack redress is eco-friendly and natural. The result on compressive strength, water absorption and water porosity of cement concrete cubes because of the blending of microorganism is additionally mentioned during this paper. it had been found that the utilization of true bacteria Megaterium improves the compressive strength and stiffness of concrete. Bactria improves the structural properties like strength, water porosity, sturdiness and compressive strength of the conventional concrete that was found by the activity style of experiment on too several specimens had variable sizes utilized by different researchers for his or her study of microorganism concrete as compared with the traditional concrete and from the experiment it had been additionally found that use of sunshine weight mixture together with microorganism helps in self healing property of concrete.

Keywords: microorganism concrete, Self healing concrete, Bio concrete, true bacteria megaterium, Compressive Strength, standard Concrete
