Application of fishery waste on window grilles cement tile

Aquaculture by-products, such as oyster shells, clam shells, and fish scales, are considered business wastes and are frequently discarded and buried without treatment, causing environmental and ecological problems. To recycle fishery waste, this study proposed using recycled materials such as oyster shell powders, clam shell powders, and fish scale fragments as aggregate substitutes in cement mortar for making cement tiles. The application of cement materials is diverse, ranging from indoor and outdoor landscape decoration and building materials to artistic creations and home decoration products. This study is proposed to produce cement tiles with a richer window grilles surface texture. First, wastes from the aquaculture industry, such as oyster shells, clam shells, and fish scales, were washed, ground, and mixed with cement mortar in different proportions to produce cement tiles, which were then subjected to relevant tests to assess their physical properties such as water absorption, compressive strength, flexural strength, and warpage. The cement tiles that meet the CNS specification for indoor wall tiles were further integrated into the window grilles processing.
