The applications of geopolymers as cementitious systems are becoming an alternative source of cement daily. The use of potentially suitable aluminosilicate inorganic waste materials incorporated with agro-industrial waste in the production of suitable geopolymer binders has been reported. Calcined clay and some agro-waste ash, such as coconut shells, are examples of aluminosilicate materials that exhibit strong pozzolanic activity because of their high silica-alumina composition. The pozzolanic reaction is primarily caused by the amorphous silica present in properly burned agricultural waste and clay. Based on a variety of available literature on concrete and mortar including geopolymers synthesized from agro-industrial waste, a critical review of raw materials and the mechanism of synthesis of the geopolymer has been outlined in this work. Additionally, the durability characteristics of agro-industrial waste geopolymer concrete and mortar, including resistance to chloride, corrosion, sulfate, acid attack, depth of carbonation, water absorption, thermal resistivity, Creep and drying shrinkage, are briefly reviewed.
