Biocement production from hard water through microbial fermentation

Description: This research utilizes the hard water which is some how non potable and to turn hard water in to biocement. Cement is considered a vital manufacturer material in construction. Because of the unparalleled advantages of cement, such as longevity, high strength, durability, and resilience, one still has major drawbacks; one is carbon dioxide emission . Cement production emits various air-borne pollutants, most importantly particulate matter, carbon dioxide, carbon monoxide, nitrogen oxides, sulfur dioxide, and volatile organic compounds (benzene, ethylene glycol, formaldehyde).
The demerits of conventional cement have significantly affected the environment. The need to find an alternative that would replace synthesis cement chemically with more efficient and cheaply produced cement is still in theoretical concept. Many researchers and scientists are working to develop cement produced using biological means. In general, the cement produced using biological means is termed bio-cement. This Bio-cement or bioconcrete is termed as the production of calcium carbonate using microorganisms through a process known as biomineralization. The process of biomineralization involves a process concerned with a chemical modification of an environment through the usage of microorganisms and their metabolic activities, for example, precipitation of minerals. The mineralization of calcium carbonate during bio-cement production consumes carbon dioxide, resulting in no carbon dioxide emission—bio-cement functions like conventional cement in terms of durability and mechanical properties. Also, in terms of advantages, bio-cement production can be achieved at 20-40ºC, unlike conventional cement production at 950 or higher temperatures. The bio-cement is highly compatible with other ingredients used for the construction due to its low viscosity property. Even the small particle size of bio-cement makes it highly porous to be used as a fine sealer in various cracks or pores
