Kaolinitic clays of different varieties were progressively added to a 70 : 30 mix of common clay and fly ash. The improvement in physico-mechanical properties upon heating in the temperature range of 1050° to 1200°C was studied by evaluating their linear shrinkage, water absorption, flexural strength and phase content. Incorporation of clay I produced better ceramic properties than that of clay II. It was observed that incorporation of kaolinitic clay up to 10% of the total batch improved the physico-mechanical properties and beyond this limit the properties, particularly fired strength, remained unchanged or marginally decreased. Microstructural features were also studied using SEM technique.
