Abstract The combined use of silica fume (SF) and ceramic waste (CW) for the production of mortar is studied. Sand is replaced by 5%, 10%, 15% and 20% of CW while a fixed 5% percentage (% wt of cement) of SF is used. The results show that the best results are obtained by using silica fume and ceramic waste sand with 15% weight of sand and 5% wt of cement. With the addition of sand ceramic waste (SCW), the mortar compressive strength and density increase, while the porosity displays an opposite trend. The experimental analysis is More > Graphic Abstract

Abstract Green and sustainable concrete has attracted significant attention from the construction industry and researchers since it was proposed. The ceramic waste materials are often directly buried in the ground or placed in an open dump, and the accumulation of ceramic waste contributes to environmental pollution, which makes the recycling of ceramic waste quite urgent. Owing to the pozzolanic activity, excellent mechanical properties and durability, industrial ceramic waste is considered as a suitable substitute for cement or natural aggregates to fabricate renewable concrete. In this paper, the pozzolanic activity of ceramic waste and the workability, mechanical… More >
