Increased concrete demand drives the cement industry to produce massively, generating CO₂ emissions equivalent to 1 ton per ton of cement. This prompts the development of eco-friendly geopolymer mortar based on fly ash, rice husk ash, and marble waste. Fly ash, rich in Si and Al, requires an alkali activator as a binder, while rice husk ash (SiO2) and marble waste (Ca) enhance mortar performance. This study tested geopolymer mortar with 12 Molar NaOH alkali concentration, with marble additions of 0%, 2.5%, 5%, 7.5%, 10%, 12.5%, 15%, 17.5%, and 20%. Tested parameters included compressive strength, porosity, and vicat. Results showed the highest compressive strength of 21.22 MPa at 12.5% marble addition, increasing from 15.255 MPa (0%) to 21.22 MPa (12.5%), then decreasing to 16.873 MPa (20%). Porosity inversely correlated with compressive strength, with the lowest value of 8.26% at 12.5% marble and the highest of 13.53% at 20% marble. Optimal marble addition at 12.5% yielded geopolymer mortar with the best mechanical performance and lowest porosity.
