MODEL APPROACH TO OPTIMISE CEMENT, CLAY AND COCONUT COIR IN STABILISED COIR BLOCKS

The paper is entitled to work on the mathematical model approach towards the optimisation of clay, cement and coconut coir percentage in stabilised soil compacts. A linear equation y = 1.4298x - 0.0214 is proposed for cement and clay percentage. Residual clay and calcium hydroxide liberation during primary hydration is estimated. Further 8% of coconut coir is modeled as optimum from mathematical approach and result in maximum dry compressive strength of 0.44 MPa experimentally.
