There is an increasing demand for lithium, which is perceived as the key element of the green revolution. This green image remains incomplete without the circular economic uptake of delithiated β−spodumene (DβS). In a recent contribution, the authors proved that DβS has remarkable pozzolanic properties (Karrech et al., 2019). This paper sheds more light on the early-age and long-term behaviour of DβS derived geopolymer by using advanced...
