This has driven research into repurposing the waste materials for various applications. Processed ceramic waste has been extensively studied in the past as a substitute for cement or sand to produce cementitious composites. However, its applications have primarily been limited to solid mortars and concrete. Here, the influence of ground ceramic tiles as a fine aggregate of hollowed masonry units (HMU) has been investigated. Ceramic waste aggregate (CWA) was introduced in HMUs at 0%, 25%, 50%, 75%, and 100% of the fine aggregate volume, and their compressive strength, densities at various moisture states, and moisture characteristics were evaluated. Results showed that adding CWA significantly improved the strength (by as much as three times), reduced the density (by 13.9%), minimally affected the absorption capacity, and lowered the material cost (by up to 21.3%) of HMU, with the 100% replacement achieving the most favorable results. X-ray fluorescence analysis showed that CWA contained a higher amount of amorphous silica than river sand, which may explain the improvement in the HMU’s engineering performance. The HMUs were found to satisfy the required strength for nonloadbearing blocks. Moreover, the block with 100% CWA was classified as medium weight while all other blocks were classified as normal weight. In summary, this study demonstrated the potential of ceramic tile waste as an aggregate alternative for nonloadbearing masonry construction.
