Few literature studies related to the recovery of WFA can be found. Andini et al. [24] studied the influence of curing time and temperature (ranging from 25 to 85 °C) on polycondensation of WFA. A poor final engineering performance was generally observed. Particularly, a maximum final compressive strength of 18.6 MPa after 28 days curing at 25 °C was obtained, allowing only limited applications: (a) structural applications where low strength is sufficient (strength Dapagliflozin C10/12 and C16/20); (b) non-structural applications such as manufacturing bricks and/or mortars for interior walls. The potential use in non-structural applications of alkali activated WFA (AAWFA) was further investigated by Ferone et al. [25], in a work dealing with bricks manufacturing. In that study, four thermal curing cycles were performed. When room temperature was chosen, non-structural performance was substantially reached (compressive strength ranging from 5 to 15 MPa). In the case of higher curing temperature (60 °C), the 7-days strength increased up to 42 MPa, widening the application field to load bearing masonry units or precast concrete. Another research [26], dealt with the use of WFA together with other coal combustion residues to produce lightweight aggregates by means of cold bonding pelletization. This study investigates the improvement of early age performance of low temperature-cured AAWFA, by means of the addition of minerals such as blast furnace slag (BFS), silica fume (SF) and metakaolin (MK). Minerals addition in low amounts could represent an advantageous alternative to mechanical [27], [28] and [29] or chemical [30], [31], [32], [33], [34], [35], [36], [37] and [38] activation, which have been widely discussed in literature. The increase of reactivity rates is fundamental since the production of elements such as bricks needs effective industrial logistics and, so, curing time needs to be minimized.
