UNCONFINED COMPRESSIVE STRENGTH OF CEMENT STABILIZED PEAT WITH RUBBER CHIPS AND SAND FILLER MIXED AT VARIOUS WATER TO ADDITIVE RATIO

Peat is known to be a very problematic soil as it has high natural moisture content, high compressibility and low shear strength, high degree of spatial variability and high permeability which requires special cnsiderations for construction over them. In Malaysia, peat soils cover 2,457,730 ha (7.4...
