Abstract : The paper mainly focuses on use of the CO2 gas that is largely emitted from the industrialized world. CO2gas with different pressures 5, 10 and 15 psi was passed into the chamber that contains sand and sodium silicate mixture where sodium silicate was used for internal/self-curing. Epoxy resin/Urethane are then sprayed over the sand brick which enhances the tensile strength of the sand brick and they are kept under direct sun light for curing (24 hours). The compressive strength test was done on the samples as per IS and ASTM codal requirements and the pressure for which higher strength were obtained was taken as efficient pressure and the same was maintained for further research. The same brick was further checked for its durability by conducting the various durability tests such as efflorescence test, leachability analysis, water sorptivity test and acid attack test. The test results obtained prove that CO2sand bricks are more strong and durable than conventional bricks and concrete.
