| Abstract: | The microstructure of a bonding film was observed and the fracture and mechanical properties of the bonding film of CO2-sodium-silicate sand with different moduli were analyzed by SEM. The model of the bonding film structure was described quantitatively by measuring the amount of CO2 absorbed. The results show that the properties of core is best when the thickness of the silicagel layer (product of chemical reaction) is 30~36% the total bonding film thickness, the modulus is 2.8 and the silicate addition is 4.0%. |
