Ay and Ünal [103] studied the use of waste ceramic tile in cement production. They replaced cement with CWP at 25%, 30%, 35% and 40%. The compressive strength gradually decreased in parallel with the increase in the CWP. In other words, it fell from 38.4 MPa at 25% to 32.2 MPa at 40% after 28 days of curing.
