In this book, Concrete is prepared for economic point of view with the help of different cutting waste of Marble /Granite / Kotastone. This study concerns mainly on the possible use of Stone waste in construction industry which would reduce both environmental impacts and the production cost. Concrete works in construction industry is particularly important as it is not only responsible for consuming Natural resources and energy but also its capacity to absorb other industrial waste. Presently large amounts of stone wastes are generated in Basaltic stone processing plants with an important impact on the environment due to its disposal. Stone Chips Aggregate are generated as a waste during the process of cutting of Marble /Granite / Kotastone.

In this book, Bacteria Concrete is discussed with important concepts along with case study. Micro-cracks are the main cause to structural failure. One way to circumvent costly manual maintenance and repair is to incorporate an autonomous self-healing mechanism in concrete. One such an alternative repair mechanism is currently being studied, i.e. a novel technique based on the application of biomineralization of bacteria in concrete. The applicability of specifically calcite mineral precipitating bacteria for concrete repair and plugging of pores and cracks in concrete has been discussed and studies on the possibility of using specific bacteria as a sustainable and concrete-embedded self-healing agent are discussed.
