APPLICATION OF GREEN SOLUTION FOR IMPROVING THE MECHANICAL PROPERTIES OF CONSTRUCTION MATERIALS

摘要

The present invention relates to use of calcite precipitating soil bacteria to improve the mechanical performance and to provide self healing properties in the building materials. The use of soil bacteria amended green solution to improve the compressive strength of concrete can be used instead of using harmful chemicals like epoxy based water proofing agents. The process involved in the production of Green Solution is environmental friendly and it is very easy to handle. The Green Solution enables pores to fill within the cement-sand matrix due to the calcite deposition. Furthermore, Green Solution is cost effective product because it is produced by the cheaper available protein source like lentil seeds as compared to chemicals like peptone, etc. Following invention is described in details with the help of Figure 1A to 1 D of sheet 1 which shows the diagram for simplified representation of the events occurring during the microbially induced carbonate precipitation, Figure 2 of sheet 2 shows the diagram for SEM of bio-OPC using peptone and Figure 3 of sheet 2 shows the diagram for SEM of bio-OPC using lentil seeds.
