Utilization of Ceramic Tiles Waste Powder on Mortar Concrete using North Sinai Materials

Abstract. Growing populations worldwide need housing, infrastructure, and essential services. This rapid growth has stressed the environment and limited the availability of construction materials. As a result, it's becoming increasingly important to research environmentally friendly engineering methods. Another option is using large amounts of ceramic tile waste powder from construction and demolition projects. Previous studies had shown that these waste materials had pozzolanic properties, which means they could potentially be a substitute for cement in construction. This study looked at compressive strength, how strength changed over time, and how well the mortar flowed. In our study, we replaced a portion of the cement with ceramic powder, using amounts from 0% to 50% of the total weight, with increments of 10%. Standard cube specimens of 70 × 70 × 70 mm were fabricated and subjected to water curing until the specified testing ages. Our results showed that 20% waste ceramic powder as a replacement represents the best result compared to other results of mortar mixes, illustrating that finely processed ceramic waste can serve well as a supplemental cementitious material. This suggests the potential to improve sustainable building methods while reducing reliance on traditional cement.
