Strength And Durabilityassessment Of Bacteria Based Self- Healing Concrete
In recent years, there is increasing interest in the phenomenon of mechanical property recovery in concrete construction using self-healing concrete. The study was motivated by the need to find a solution for the problem of cracking approaching the concept of self-healing concrete. The study was carried out on a bacteria based self-healing concrete using Bacillus Subtilis bacteria. The present ...
متن کاملAssessment of self-healing capabilities, a route towards standardization
ID No : ACM-01 ABSTRACT In the last decade, an increasing attention has been given to the development of repairing capabilities in materials, with an emphasis in specific strategies that can promote self-healing, with or without external triggers. Self-healing has opened several new possibilities, especially in applications where long-term reliability is demanded and either maintenance or repla...
متن کاملBacteria-based self-healing concrete to increase liquid tightness of cracks
Concrete is a remarkable structural material that has been widely used in the modern age. Nevertheless, natural causes that affect durability and consequently service life of concrete are related with surface damage and cracking of the material. Cracks can influence functionality for liquid retaining structures and can also decrease durability due ingress of water and ions towards steel reinfor...
متن کاملBacteria-based Self-healing of Concrete: Effects of Environment, Exposure and Crack Size
The effect of water-borne contaminants on the durability of concrete is well-known and cracked concrete is more susceptible to permeation of these contaminants. An approach to autonomic self-healing of such concretes is the utilization of microbiologically-induced calciteprecipitation. This approach uses the metabolic activity of bacteria and biomineral precursors embedded within the concrete t...
