Upcycling and reclaiming of low quality or stored coal combustion fly ashes could enable to tap into a voluminous resource supplementary cementitious materials (SCMs) for low-carbon blended cements. Low reactivity are usually either too crystalline coarse. Beneficiation treatments coarse comprise size classification milling processes extract produce fine fractions higher pozzolanic reactivity. ...

This study investigates the effectiveness of concrete protection with two inorganic silicate sealer materials (ISSMs). The Taguchi method and grey relational analysis (GRA) have been used to identify the key factors influencing concrete protection provided by the surface treatment. Seven control factors with two levels were selected. By using the orthogonal array L12 (2⁷), 12 experiments are ch...

Abstract Spent fluorescent lamps glass (SFLG) waste, manually and mechanically processed in a waste treatment plant, was used to partially replace up 50 wt% Portland cement (PC). Both types exhibited similar pozzolanic activity. The mortars containing 35 wt% SFLG met the specifications for other materials (e.g. fly ash) and, after 90 curing days, their compressive strength values were or higher...

Green and sustainable concrete has attracted significant attention from the construction industry researchers since it was proposed. The ceramic waste materials are often directly buried in ground or placed an open dump, accumulation of contributes to environmental pollution, which makes recycling quite urgent. Owing pozzolanic activity, excellent mechanical properties durability, industrial is...
