The relatively low compressive strength of conventional glass ionomer cements limits their use in stress-bearing areas, necessitating evaluation of newer reinforced variant. Therefore, it is of interest to evaluate compressive strength of different types of glass ionomer cements (GIC): conventional GIC (Group A), Zirconomer (Group B) and Amalgomer CR (Group C). Each group consisted of 12 specimens formed in plastic straws with 4mm 6mm dimension. Compressive strength was assessed using a universal testing machine at a crosshead speed of 1 mm/min. Result showed that Zirconomer exhibited the highest compressive strength, indicating its superior performance compared to the other materials.

Strength of Cement
For compressive strength tests, ASTM C 109-05 standards prescribe a cement-sand mix ratio of 1:2.75 and a water/cement ratio of 0.485 for making 2-inch cubes. These cubes are mixed, cast, and cured in saturated lime water at 23°C until testing. Flexural strength testing, outlined in...
