MODELLING OF CRYSTAL GROWTH IN PEAT SOIL STABILIZED WITH MIXING OF LIME CACO3 AND FLY ASH

Peat soil stabilization produces improved parameters because of the admixture added to form crystals that fill the pore and wrap the peat soil. Crystal growth is strongly influenced by the filtration of water from its surroundings, the width of area stabilization, and the curing periods. To predict the parameter behaviour of stabilized Peat Soil during the curing periods, the Difference Method is employed by assuming crystal growth occurs in porous media. Control equations are built on the behaviour of peat crystal growth, mass conservation, and Darcy's law. Numerical computing is based on several control statements made and completed with the assistance of Mat Labs software. The prediction of stabilized Peat Soil parameters is modelled in the width of the stabilization area and the different curing periods. Predictive results through numerical computing show that the soil volume, porosity and flow of stabilized peat fluid in the stabilization area of 70 is the most optimal value compared to the width of the other stabilization areas.
