The enormous quantities of ceramic waste lead us to its use in the construction field to solve both an environmental and an economic problem. The present study aims to recycle ceramic waste powders (CWP) to produce mortars. To this end, five crushed sand (CS) based mortar mixes with prismatic dimensions of 4x4x16 cm³ were prepared by partially replacing 0, 5, 10, 15, and 20% white cement with CWP. Tests were carried out to assess bulk density, compressive strength, and ultrasonic pulse velocity (UPV). The results obtained showed that increasing the proportion of ceramic waste powder (CWP) in mortar mixes led to a decrease in bulk density, compressive strength, and UPV in the different mortars. In addition, linear correlations were observed between the different variables studied.
