Abstract

This study addressed the environmental constraints in cement produc­tion. Ordinary Portland cement (OPC) was replaced with pottery powder (PP, produced by grinding locally available pottery) and bottom ash (BA) at 10%, 20% and 30% of cement mass. Moreover, 4% calcium chloride solution (CaCl₂.2H₂O) was used as mixing water. Material properties, such as standard consistency, setting time and compressive strength, were measured with different percentages of OPC replacement with PP and BA. Results indicated that the replacement with PP and BA increased the water demand to achieve the standard consistency. These results revealed that the strength evolution of 30% PP and BA is lower than that of the corresponding OPC mix, whereas the 10% and 20% replacements have a similar compressive strength to the control mix at 28 and 90 days, respectively. Slightly higher compressive strength was observed with the addition of 4% CaCl₂ than the OPC mix.
