The goal of this study is to improve concrete’s efficiency by using a microbiologically produced specific growth/filler. One such way of thinking has resulted in the invention of a highly unusual concrete known as microbial concrete, which uses bacteria to cure flaws in the concrete. Investigators working with various microorganisms suggested several microbial concretes. The bacterium “Pseudomonas” was used in this experiment. Pseudomonas bacteria, which can make calcite precipitates on a proper medium supplied with a calcium supply, is a typical science lab bacterium for calcite generation. Two different concentrations (106 cfu/mL and 107 cfu/mL) of bacteria were added to cement concrete and it was observed that the bacterial concrete with two different concentrations gives results as compared with normal concrete. According to the findings of this investigation, the inclusion of bacteria resulted in a considerable increase in compressive strength when the dilution factor was 106 cells per ml of mixed water. With the incorporation of the microorganisms, it was discovered that holes were partly filled up by material growth, as shown by scanning electron micrography inspection of the sample. Concrete cubes without and with the inclusion of bacteria were molded, and it was discovered that the compressive strength of the cubes with the injection of microorganisms increased significantly. In this study, concrete cylinders without and with the inclusion of microorganisms were molded, and it was discovered that the split tensile strength of the cylinders with the injection of microorganisms increased significantly above the control. When compared with regular concrete, the results showed a maximum increase of 16 percent in compressive strength and a maximum increase of 12 percent in split tensile strength. It was discovered via durability testing that bacterial concrete had less weight loss and stronger tensile strength than conventional concrete when treated with 5 percent H2SO4 or 5 percent MgSO4 compared with control concrete.

The focus of this research is to isolating and identifying bacteria that produce calcite precipitate, as well as determining whether or not these bacteria are suitable for incorporation into concrete in order to enhance the material’s strength and make the environment protection better. In order to survive the high “potential of hydrogen” of concrete, microbes that are going to be added to concrete need to be able to withstand alkali, and they also need to be able to develop endospores so that they can survive the mechanical forces that are going to be put on the concrete while it is being mixed. In order to precipitate CaCO3 in the form of calcite, they need to have a strong urease activity. Both Bacillus sphaericus and the Streptococcus aureus bacterial strains were evaluated for their ability to precipitate calcium carbonate (CaCO3). These strains were obtained from the Department of Biotechnology at GLA University in Mathura. This research aims to solve the issue of augmenting the tension and compression strengths of concrete by investigating possible solutions for environmentally friendly concrete. The sterile cultures of the microorganisms were mixed with water, which was one of the components of the concrete mixture, along with the nutrients in the appropriate proportions. After that, the blocks were molded, and then pond-cured for 7, 28, 56, 90, 120, 180, 270, and 365 days, respectively, before being evaluated for compressibility and tensile strength. An investigation into the effect that bacteria have on compression strength was carried out, and the outcomes of the tests showed that bacterial concrete specimens exhibited an increase in mechanical strength. When compared to regular concrete, the results showed a maximum increase of 16 percent in compressive strength and a maximum increase of 12 percent in split tensile strength. This study also found that both bacterial concrete containing 106, 107, and 108 cfu/ml concentrations made from Bacillus sphaericus and Streptococcus aureus bacteria gave better results than normal concrete. Both cluster analysis (CA) and regression analysis (RA) were utilized in this research project in order to measure and analyze mechanical strength.

AbstractAccording to the global agencies of world health organization, world metrological organization and UNICEF, the utilization of fresh water goes on enlarging from twenty century due to overpopulation and frequent implementation of safe accessible water in relative fields, diminishing the quantity and quality available which ultimately causes gap between ecology and environment for livable water. In our construction industry, this safe water can be saved to a large extent by just interchanging this water by various water available viz. seawater, waste water, sewage water and waste wash water based on literature data and studies which show normal and insignificant changes in the strength of cement hardened concrete. This literature based study will provide the base for adoption of waste water a as source in the construction field for preparing the formwork and a small donation towards national water saving programs launched by government of India.
