Possibility of Lime as a Stabilizer in Compressed Earth Brick (CEB)
This paper highlights the production of lime, chemical reaction during the production process, lime reaction with the soil and the prospective use of lime in the future. The research works that has been carried out showed lime has superior properties than cement in enhancing soil structure and also exhibits less embodied energy than cement. The lime through its chemical composition, calcium hydroxide, able to reacts with the pozzolanic materials that presents in the clay soil. This pozzolanic reaction resulted to the formation C-S-H cementitious gel that will further stabilize the soil. The application of lime will also promote healthier environment since carbonation process that occur during carbonation period absorb carbon dioxide in the air. The production of compressed stabilized earth brick using lime will also contributes to greener environment as compared to normal brick production method which consumed extensive energy.
