The use of copper slag as a pozzolanic material for a partial substitute for ordinary Portland cement and its effects on the hydration reactions and properties of mortar and concrete have been reported in several publications (Al-Jabri et al., 2006, Taha et al., 2007, Malhotra, 1993, Tixier et al., 1997, Ariño and Mobasher, 1999, Douglas and …
Eco-Efficient Concrete: A sustainable reutilization of Ceramic Tile Waste Powder (CTWP) as a partial replacement for cementitious material in a recycled fine. aggregate concrete.
Concrete recycling is a well-established industry in many countries, albeit limited to the simple crushing of waste concrete and using only the coarse fraction as aggregate. The fine fractions generally remain undervalued, meaning an obstacle for full re-utilization and commercialisation of waste concrete. Low recovery rates also affect the ...
