New technologies have helped to develop new forms of construction and alternative materials within the concrete area. One of most recent and advanced way of improving mechanical properties of concrete is through mineralization of bacterial isolates. Bacterial organisms have the unique capacity to produce calcite through metabolic activity. This paper investigates the prospect of achieving the higher strength of the concrete by using the microbiologically induced unique growth or filler. Here an investigation was done by using the bacteria "Bacillus megaterium" utilized in concrete grade of M70. The purpose of this research is to check the strength and costing of varied concentrations 10 3 cells/ml, 10 5 cells/ml and 10 7 cells/ml of bacterial concrete with conventional high strength concrete of M70 grade and to determine the optimum concentration. Bacterial concretes shows compressive strength compared to traditional concrete. The concentration 10 5 cells/ml gives optimum result compared to other concentrations. Index Terms-Bacillus Megaterium, Bacteria, Bacterial Concrete, Compressive Strength (CS), High Strength Concrete (HSC) 2.1. Bacterial Strain Generally when the water and cement water are mixed together they has pH value up 12. Most of the bacteria cannot survive in environment having pH 10 or more. Bacillus megaterium bacteria can survive in the environment which is having pH 12 or more and also can grow without oxygen if the nitrate is present. Bacillus megaterium bacteria can be generally found at the interface of root soil, in decomposing plant residue, air, soil, water and air. For this research work the bacillus megaterium

There are different types of concrete available for special kind of requirements for the structure and applications. Also various innovations are taking place day by day in the concrete domain. High strength concrete is needed for heavy loaded structures. Some of the application includes dams, high-rise buildings, long span bridges, heavy duty industrial floors, parking garages etc. For production of high strength concrete various pozzolonic materials along with various chemical admixtures are utilized which raises the cost. Bacteria included concrete is a new research area and can be used for cementitious materials that cure itself automatically using calcite precipitation characteristics of bacteria. The idea of introducing bacteria in concrete, is to precipitate calcite in pores which will give higher strength to the concrete. This paper reviews various types and applications of bacteria which are used in ...

Production of huge amount of industrial waste is one of the most severe problem of this entire world. The problem related with the disposal of waste materials can be minimize by using the waste materials in effective manner. Fly ash is one such material which is a by-product of thermal power stations. For the disposal of fly ash very large area is needed which affects the environment adversely. Disposal of large quantity of fly ash from thermal power plants grasp large quantity of natural resources. So, the problems regarding their proper management and disposal has become a major task to environmentalists and scientists. Fly ash has several uses in construction sector like brick making, fill material in concrete, in road construction, production of mosaic tile, waterproofing etc. based on its properties and requirements in exposure conditions. This paper review the various properties and applications of fly ash in construction industry in recent times.
