Received: 13 November 2020 Revised: 16 December 2020 Accepted: 17 December 2020 Published: 21 December 2020. Geopolymer cement has been popularly studied nowadays compared to ordinary Portland cement because it demonstrated superior environmental advantages due to its lower carbon emissions and waste material utilization. This paper focuses on the formulation of geopolymer cement from nickellaterite mine waste (NMW) and coal fly ash (CFA) as geopolymer precursors, and sodium hydroxide (SH), and sodium silicate (SS) as alkali activators. Different mix formulations of raw materials are prepared to produce a geopolymer based on an I-optimal design and obtained different compressive strengths. In most construction activities, cement-based concrete is an essential and widely used material. The use of cement-based concrete, like ordinary Portland cement (OPC), is globally accepted due to ease of operation, excellent mechanical properties, and low-cost production compared to other construction materials 2. However, OPC has drawbacks as it releases approximately one ton of CO 2, a greenhouse gas, to produce one ton of OPC 3. It also has high energy consumption during production, and it consumes a significant amount of natural resources 2, 3. Due to increasing awareness of these issues, a viable alternative for the conventional Portland cement is currently being reviewed and studied by many researchers and scientists.
