Abstract
Ceramic waste deposit poses a number of environmental challenges, ranging from air, water and soil contaminations. Thus, the present investigation is centred on evaluating the technical viability and environmental benefits of using ceramic floor and wall tile wastes in sustainable concrete mixes. Both geotechnical and microstructural analysis were performed on three phases of the ceramics waste preparation: as powder, fine and coarse, and compared with the natural aggregates. Regarding the physical properties, ceramic tile aggregates performed adequately well as the natural aggregates, except for the high water absorption observed in ceramics. Chemical composition tests conducted on the ceramic tile indicated that it possesses 64.557% silica, which is a pronounced feature of pozzolans. Consequently, ceramic floor and wall tile wastes can be processed for reuse in concrete.
