Integrating Fine Ceramic Tile Aggregates in Concrete Hollow Blocks

Abstract

This study investigates the effect of fine ceramic tile aggregates (CTA), specifically floor and wall tiles, as a replacement for fine aggregates in non-load bearing Concrete Hollow Block’s (CHB) fresh and hardened properties. The experimental design of this study performed was in line with the American Society of Testing and Materials (ASTM) standard procedure. Results for the workability of CHB with CTA showed comparable behavior to the control mix, which ranged between low to medium slump values (49 mm-59 mm). Specimens with CTA are characterized by higher water absorption and lesser density and moisture content. All the CHB with CTA replacement yielded higher compressive strength than the control mix. The 30% CTA substitution gained the highest compressive strength of 3.20 MPa (462.12 psi) for 28-days of curing. Overall, the physical and mechanical qualities of the samples with CTA percentage performed better than the control mix.

Moisture susceptibility of waste ceramic tiles modified asphalt mixtures

“…Most of the construction and demolition (C&D) wastes produced by Nigeria's building industry throughout time is solid waste; ceramic tiles contribute the highest percentage of waste within the C&D wastes [1][2]. According to Ramirez et al [3] about 54% of the C&D waste in the stony fraction comes from ceramic tiles. Most of these waste ceramic tiles are not recycled and instead end up in landfills, taking up valuable space and costing money in landfilling [4][5].…”
