The present study was carried out to determine the engineering properties of foundry sand to demonstrate the process parameters of CO2-silicate moulds by using “Design of Experiments? in which all the variables will vary simultaneously. A temporary mould is prepared with the mixtures of sand, Sodium silicate to bind sand grains and some additives like bentonite and CO2 gas were used to hydrolyze the mass of silicate sand. The process parameters considered are CO2 gassing time, sand particle size, percentage of Sodium Silicate and time taken for heating process. The experimental investigations of thermal properties namely thermal diffusivity is studied to determine the effect of Sodium silicate, CO2 gassing time. The adequacy of models is tested by the Analyses of Variance ANOVA which uses a computer program and accuracy by experimental data. Thus, the findings of this research suggest that the determination of individual, interactive and higher order effects of process parameters on the thermal properties of foundry sand are identified to a greater extent the rate of heat extraction from castings and also influences their quality of castings.
