摘要

In view of the environmental degradation associated with production of Ordinary Portland Cement (OPC), geopolymer cement is drawing attention as an ecofriendly alternative. This study investigates the sustainable utilization of waste Ceramic Dust (CD) collected from ceramic industry, for production of geopolymer cement through alkaline activation under different conditions. The ceramic dust based geopolymers block exhibited 7 days compressive strength of 4.95 MPa, by activation with 10 M NaOH, sodium silicates to ceramic dust ratio of 0.5, and 10% Ca(OH)2 at 60 °C. In comparison, the OPC block of same size showed a compressive strength of 6.68 MPa after 28 days, whereas the geopolymer mortar sample showed a maximum of 6.23 MPa. For the large size ceramic dust block, the 28 days compressive strength of mortar mix was about 53.16 MPa under optimum conditions. Addition of 5% of slag and waste glasses as a reinforcing agents improves the compressive strength of the geopolymers by 7–10%, making its comparable to that of OPC. The geopolymer material shows excellent durability for acid and heat. These results indicate that geopolymer cement made from ceramic dust has the potential to be utilized as a building material.
