Abstract

The ceramic tile industry produces about 30 million square meters of tiles annually and about 30% of its daily production goes to waste. The current option for disposal of this waste is sanitary landfill. A practical way to reduce the volume of waste ceramic tile disposal is to recycle them through concrete manufacture. This study with the intent of extending the recycling of waste ceramic tiles by determining its viability in concrete production, presents results regarding the effect of replacing sand with fine ceramic aggregates (FCA) on the compressive strength and workability of concrete. The FCA used in the study are unglazed waste ceramic tiles. The FCA replaced sand at 25% 50% 75% and 100% by total fine aggregates volume in concrete. Results of the experiment showed that increasing the FCA content adversely affects the workability of concrete. On the other hand, increasing the FCA content up to 50% showed an increase in compressive strength with respect to the reference concrete. However, further increasing the FCA content 75% to 100% already displayed lower compressive strengths relative to the reference concrete. With this, in terms of compressive strength, replacing sand with FCA by up to 50% of the total volume of fine aggregate can be a viable option for concrete production.
