Abstract

Ceramic tile wastes are inevitably produced at the end of its construction. It is generally disposed on landfills or any vacant spaces and is not being reused or recycled in any form. Ceramic tile wastes are proven to be rigid, firm and light that verifies its use as a good substitute material for an aggregate. In the Philippines, a previous study on the investigation of compressive strength of concrete partially replaced gravel with coarse ceramic aggregated (CCA) revealed a direct relationship between the compressive strength and the amount of CCA in concrete. In this study, the durability of concrete was tested to further promote its use as a substitute aggregate. Five specimens were created for each setup. Specimens were created with replacements by mass of 0%, 5%, 10%, 15%, and 20% CCA and were molded and cured for 28 days. Specimens were subjected to salt ponding for 60 days and brought back to laboratory for the durability test. Using colorimetric test, the depth of chloride ions were detected and measured. Average depth between setups were determined and compared. The results showed a consistent decrease of chloride ingression in concrete as percent replacement increases. Statistical analysis, physical analysis and chemical analysis were used to further discuss the results. It was concluded that incorporating CCA in concrete provides a good durability in concrete which can be promoted as a good substitute material to gravel.
