EXPERIMENTAL INVESTIGATION ON MECHANICAL PROPERTIES OF BACTERIAL CONCRETE
Manohar Kumar Mishra, Er.Yashpal Kumar
Abstract
Comparatively, bacterial-based self-healing concrete is a new technology, so before being applied on larger-scale applications, it is important to gather more data in real-world conditions. Different kinds of bacteria used in concrete and how they are used as curing agents are discussed in this work. The different properties of concrete, which vary with the addition of bacteria, are also briefly defined in this article. Inherently, micro cracks in concrete are present, allowing the concrete to degrade, causing toxic chemicals to penetrate the concrete, contributing to structural degradation. Self-healing methods are used to resolve these conditions. Sources of calcite and calcium are created by the addition of bacteria that cause calcite precipitation in concrete. For sealing micro cracks in concrete, bio-mineralization technology provides promising results. A permanent process of hydration in the concrete will seal the freshly formed micro cracks. The benefit of concrete is that it is readily accessible, less expensive and easy to cast. Concrete structures are very prone to cracking, allowing chemicals and water to penetrate into the concrete that degrades the strength of the concrete, thus reducing the structure's efficiency. Eco-friendly concrete is planned to solve this problem. By injecting bacteria into normal concrete, this concrete is made. The bacteria that are grown are applied to the concrete of M- 25. The main aim of this research work is to evaluate the output of the specific filler induced and microbiologically obtained concrete. In this analysis, a variety of experiments are carried out at 7, 14 and 28 days on normal concrete and bacterial concrete including water absorption, compressive strength, ultrasonic pulse velocity (UPVT) test, flexural test and slumptest.
