Schematic representation of the possible formation of bonds between dimethylpolysiloxane and aluminosilicate units during the polycondensation process that allows for the obtainment of a hybrid material according to the synthetic procedure described in [16]. The scheme only represents a possible situation that highlights the chemical bond formation between the organic and inorganic moieties in the final hybrid material since fly ash (FA)-based alkali-activated binders are often highly heterogeneous due to the variable chemical and physical nature of the particles present in the FA used as a precursor and the complex reactions taking place during alkali activation.
