Study On Mechanical Properties Of Fibre Reinforced Bacterial Concrete

Abstract

The most used building material in the world is concrete, which is made of cement aggregate and water. It is a strong, long-lasting substance. However, fissures in concrete are unavoidable and one of the material's intrinsic weaknesses. The main drawback of concrete is that it has low tensile strength, which leads to micro cracks. By enabling corrosive substances to enter the concrete matrix, which causes steel to corrode and lose tensile strength, micro cracks in concrete also reduce durability. Such an occurrence could result in more serious issues like spalling or even premature structural breakdown. Concrete structure maintenance and repair require a lot of labour and money. After construction is complete, it can be challenging to assess the extent of damage. Moisture entering fractures can lead to corrosion, which weakens the entire structure and eventually causes it to collapse. Introduce bacteria now into concrete to lessen these fissures. Self-healing could be the answer. There are numerous methods of self-healing, such as the ability of concrete cracks to self-generate and self-heal. When water seeps into the cracks, bacteria react with it and precipitate calcium carbonate as a byproduct. This fills the crevices and creates concrete that is crack-free. Additionally, while adding Polypropylene Fibers to concrete to increase its strength.
