Abstract. Geopolymer is a product of aluminosilicate materials with a strongly alkaline solution mixture, curing it at a low or slightly high temperature. Because of its low energy consumption and low carbon emissions, clay brick is recognised as a green, sustainable construction material. It is formed by three main stages of the geopolymerisation process: the dissolution of aluminosilicate materials, the nucleation growth and polymerization of monomers, and the reorganisation and polycondensation of those monomers. However, there is one critical element that should be noted, which is the reactivity of the precursor, which will affect the overall geopolymerisation process and also the final product, geopolymer. There are four factors that will affect the reactivity of a precursor: chemical composition, glass phase content, morphology, and mineralogy. If there is an issue with the low reactivity of a precursor, there are three techniques, which are thermal, chemical, and mechanical treatment, to transform it into high reactivity properties. In conclusion, with respect to the manufacturing of geopolymer bricks, also called non-fired clay bricks, the properties of the precursor in terms of reactivity should be considered in order to achieve the desired properties in the construction field.
