Abstract

A large amount of the tile industry goes to waste and is considered "off-quality" due to their physical appearance but the mechanical and chemical characteristics of ceramics are still intact. Due to the high demand for concrete, the supply for the conventional aggregates is depleted at an alarming rate. It was found out on a study of PHILVOLCS and NEID that the strength of Philippine CHB is of less quality compared to Japan CHB. This study investigates on the possibility of incorporating ceramic tile waste in CHB to improve its compressive strength and bulk density and at the same time help maintaining the environment. Five batches with 0%, 10%, 15%, 20% and 25% partial replacements (by volume) of the ceramics were produced and tested. The water-cement ratio and the cement-sand ratio were maintained at a constant 0.5 and 1:5 respectively. The specimens were cured for 28 days. It was found out that incorporating ceramic tile waste generally improves the properties of concrete hollow blocks. Specifically, it was found that increasing the partial replacements of ceramic tile waste increases the compressive strength and decreases the bulk density of CHB.
