Recycled materials have gained extensive recognition in many industrial sectors for enhancing sustainability and reducing environmental impacts. Combining ceramic tile waste (CTW) in concrete mixes with recycled aggregate will help lower natural aggregate demand and reduce the amount sent to landfill. This paper aims to study the mechanical properties of CTW in concrete mixes as a brick aggregate replacement and its impact on concrete strength and durability. To evaluate and assess their strength and durability, three types of concrete cubes were prepared using 20%, 40%, and 70% of waste ceramic tiles as a replacement for coarse aggregate. Two kinds of concrete samples were also prepared with conventional coarse aggregate as the control specimen (CC). A 1:2:4 concrete mixed ratio was used in this research with a 0.50 water-cement ratio. The samples were tested after 14 days and 28 days to assess their mechanical properties, including strength and durability. When CTW was added to concrete mixtures instead of brick chips, the mechanical strength rose considerably, and the water absorption performance increased. Moreover, replacing brick chips with ceramic waste in concrete could have significant environmental benefits.
再生材料在许多工业领域已获得广泛认可，有助于提高可持续性并减少对环境的影响。在混凝土混合料中，将瓷砖废料（CTW）与再生骨料相结合，将有助于降低对天然骨料的需求，并减少送往垃圾填埋场的数量。本文旨在研究混凝土混合料中作为砖骨料替代品的CTW的力学性能及其对混凝土强度和耐久性的影响。为了评估和评定它们的强度及耐久性，制备了三种混凝土立方体试件，分别用20%、40%和70%的废瓷砖替代粗骨料。还制备了两种以传统粗骨料作为对照试件（CC）的混凝土样品。本研究采用1:2:4的混凝土配合比，水灰比为0.50。在14天和28天后对样品进行测试，以评估其力学性能，包括强度和耐久性。当用CTW替代混凝土混合料中的砖屑时，力学强度显著提高，吸水性能增强。此外，在混凝土中用陶瓷废料替代砖屑可带来显著的环境效益。
