search aimed to study the geopolymer paving blocks made from fly ash and bagasse ash under different curing conditions. The fly ash was replaced by bagasse ash at 10, 20 and 30% by weight of the binder. Sodium hydroxide and sodium silicate solutions were used as activated solutions. Three curing methods were studied: curing with plastic wrap (PT), curing at 35 °C for 1 hour (OV), and curing with sunlight (SU). Compressive strength and water absorption were investigated. The surface characteristics of the geopolymer paving block were studied using microstructure techniques. Sun curing provided the highest compressive strength. The water absorption values increased with an increase in the replacement percentage of bagasse ash. The surface of the geopolymer paving blocks showed remnants of the starting materials from the reaction. The geopolymer paste from the geopolymerization reaction was also found. This indicated the beneficial use of waste materials to produce environmentally friendly building materials.RELATED ARTICLE
