Here we show that recovered cement paste can be reclinkered if used as a partial substitute for the lime-dolomite flux used in steel recycling nowadays. The resulting slag can meet existing specifications for Portland clinker and can be blended effectively with calcined clay and limestone.

Abstract. Two processing techniques, i.e., grinding and calcination taken on fine powders from recycling of concrete and clay bricks (RCP/RBP) as construction and demolition wastes (CDW) were evaluated in terms of their efficiency, energy consumption, and cost. It was found that replacing OPC with 20 % non-processed RCP/RBP led to up …

Recycling concrete waste as recycled aggregate is one of the strategies to reduce the concrete waste. We can make contribution to decrease the total environmental effect of the building sector by recycling concrete debris. To amplify the scope for recycling in the future, components of recycling have to be covered in the layout phase.
