    The increasing demand for cement in the construction industry has intensified the depletion of natural resources and accelerated environmental impacts associated with cement production, including high CO<inf>2</inf> emissions. Simultaneously, the ceramic tile manufacturing process generates substantial amounts of waste, particularly sludge waste and rectified tile waste, which are typically discarded despite their high silica and alumina contents. This study examines the potential of utilizing ceramic tile waste as a partial replacement for cement in mortar formulations, promoting sustainable material use. XRF and XRD analyses revealed substantial SiO<inf>2</inf> concentrations in both waste types, indicating suitability for pozzolanic reactions. Mortar samples containing varied amounts of tile waste were examined for physical properties, compressive strength, and microstructural characteristics. The replacement of 50 % of cement with rectified tile waste significantly enhanced long-term strength, surpassing that of the 100 % cement control at 28 days, due to improved pozzolanic activity and a denser microstructure. Conversely, the replacement of sludge waste led to reduced strength due to higher porosity and weaker hydration. Further investigation of rectified tile waste at replacement levels of 30-70 % confirmed that 50 % substitution provides the optimum balance between strength performance and material sustainability. Microstructural analysis with SEM confirmed these findings, revealing well-formed C-S-H and reduced pore spaces at the optimal replacement ratio. Overall, rectified tile waste demonstrates strong potential as a sustainable cement replacement material, offering reductions in cement consumption, CO<inf>2</inf> emissions, and ceramic waste disposal while maintaining or improving mechanical performance.

    Ceramic tiles are commonly used in non-structural components of a building such as walls, partitions, floors, and roofs. However, due to their high surface hardness and density, ceramic tiles are not an ideal soundproof material. To improve the sound properties, this study introduced the use of a viscoelastic polymer sheet (VPS) as an acoustic control treatment. The VPS was attached to ceramic tiles in 4 different patterns: X, Cross, Corner, and Strip. The ceramic tiles with VPS were tested for the damping property and sound insertion loss (IL) and then compared to the ones without VPS. Results indicated that the attachment of VPS improved the damping property of the ceramic tiles. All tiles with VPS exhibited higher damping loss indexes than the ones with no VPS. The highest damping loss index of 0.017–0.018 was observed in the specimens with VPS in X and Cross patterns. In the case of IL, the performance of all ceramic tiles was indifferent when tested at sound frequencies smaller than 1000 Hz. At the sound frequencies above 1000 Hz, the best performance was observed in the specimen with VPS in the Cross pattern, followed by X, Strip, and Corner patterns, respectively. This concluded that the use of VPS can improve the damping property of a ceramic tile which also leads to the improvement in sound insertion loss.
