A review of ground waste glass as a supplementary cementitious material: A focus on alkali-silica reaction

Does national environmental regulation promote convergence in separate waste collection? Evidence from Italy

“…The convergence in terms of separate waste collection and its items is relevant because it allows to reach important objectives common to all the regions, especially to laggard regions, Southern Italian ones, which have an additional impact both on the economy (Bueno et al, 2020) and clean production (Fatimah et al, 2020). In particular:…”

Extraction of Alkalis from Silicate Materials Part 1—Amorphous Silicate Materials

“…Currently, there are many works are devoted to the issue of using glass waste as additives to Portland cement [7,[29][30][31][32][33][34][35][36][37].…”

Decarbonisation of calcium carbonate in sodium hydroxide solutions under ambient conditions: effect of residence time and mixing rates

“…The present study also aims to clarify the equilibrium between the species Na 2 CO 3 ÁH 2 O and Na 2 CO 3 at the processing conditions considered, since the co-production of Ca(OH) 2 and Na 2 CO 3 ÁH 2 O implies the need for a following separation of the products, crucial for their individual sale or use, not discussed here. For instance, high Na contents (above 2 wt%) would prevent the use of Ca(OH) 2 for cement production, 27,28 limiting the applicability of this novel technology. Since the solubility of the different species here involved would likely play a key-role for their effective separation, the present study also assessed the precipitation of the by-product Na 2 CO 3 ÁH 2 O or Na 2 CO 3 (x = 0, 1 in eqn (3), respectively) depending on the reaction conditions used.…”
