Abstract

Concrete is the most common and widely used construction material. In the concrete structure, cracks are sometimes produced due to external loads and other reasons. Due to cracks, the concrete begins to take compression loads in the structure; therefore, repairing such cracks is essential. Different methods are used to repair the cracks in concrete, but in this thesis, we are working on bacteria base self-healing of cracks in concrete. For self-healing concrete different types of bacteria are used but we are using the bacteria named Bacillus subtilis in concrete. By adding bacillus subtilis and calcium lactate we find that the concrete becomes more strengthened and self-healed as compared to normal concrete. There are two methods of adding the bacteria to concrete which is direct adding an encapsulation method. We followed the direct application method in this method the bacteria is added directly to concrete. The test results show that the bacterial concrete has higher compression strength and self-healing concrete.

Abstract

This study aims to produce Ultra-High-Performance Concrete utilizing locally available material. The experimental study includes silica fume with rice husk ash in combination with steel fibers. Various trials were made using different volumes of local materials and steel fibers to produce UHPC. Different properties were evaluated, such as compressive strength, tensile strength, and Scanning Electron Microscopy (SEM). Results show that UHPC can be produced using locally available materials as both the properties were examined with and without heating at higher temperatures and providing satisfactory strength. SEM tests were also performed to evaluate the microstructural study of the ultrahigh-performance concrete. SEM observations discovered that the transition zone between fine aggregates and the cement paste is improved by using silica.
