Bio-Concrete Tech

One of the concrete properties is that they will always crack. With good design and good application this crack can be reduced, but even small cracks can cause great problems. Clogged concrete will withstand water resistance and concrete resistance to freezing of concrete will be limited. Also, the hardness of cracked concrete will be greatly reduced. Through the moisture and oxygen cracks are able to reach the rebar which can cause corrosion of the steel. This can cause serious damage to the concrete structure. Repairing damaged structures is expensive and often causes discomfort. Especially for infrastructure, the maximum availability of our tunnels, bridges and bridges is an important precondition. Structural integrity is an important aspect of marine structures. The erosion of concrete from sea water (salt) can be catastrophic for water retention structures and can result in high maintenance costs. Would not it be nice if these structures were able to reform themselves? Self-treated concrete was developed at Delft University of Technology and is based on a self-processing system that can be achieved by micro-organisms produced from limestone. When bacteria interact with oxygen and water, they can convert some nutrients into calcium carbonate (limestone).
