A STUDY AND ANALYSIS ON PROPERTIES OF HIGH STRENGTH BACTERIAL CONCRETE

  • Rajeev Yadav, Amit Richariya

Abstract

High-strength concrete is indeed a new progression in concrete technology. It groups compressive strength of 40 MPa or above. Since HSC is another kind of solid, it has not been broadly utilized by the designers. Because of absence of research, it has just been utilized as a part of some reinforced concrete members and few large and precise structures. In our study, we will try to discover the ideal extent of mineral admixture with cement to accomplish most extreme packing density and make a mix design based on the obtained results. We will be utilized five mineral admixtures as a pozzolanic material in cement. The mineral admixtures utilized were Quartz powder, Fly ash, Metakaolin, Ultra-fine slag and Rice-husk ash. A third-generation superplasticizer will also be additionally used to set up the mix design with a specific end goal to minimize the water necessity for cement hydration. In this study we will also like to address two challenges that are commonly faced with concrete. One is the negative impact produced on environment due to huge Carbon Dioxide emission during cement manufacturing. We will try to in cooperate some greener materials partially replacing the cement in order to reduce harsh effect on environment. Crack development is also another bigger challenge that is faced by concrete. Crack development in high strength concrete is not a common phenomenon due to higher pore refinement and interface refinement. But with later ages if cracks developed it will deteriorate the structure. We can also do its reaping by filling those cracks, but it is not a sustainable technique. In this study we will try to make a concrete that will be able to heal its crack with the help of calcite precipitating bacteria. So that it can provide us a more sustainable structure. Keywords: Bacteria, Self-healing concrete, High strength concrete, Crack, Mineral precipitation, Biomineralization.
