Concrete specimens were produced with CEM I 42.5 R, crushed stone in the range of 0–4, 4–16, and 16–31.5 mm sizes and crushed ceramic 0, 25, 50, 75, and 100 %. Concrete specimens were cured in standard condition until 28-day strength was achieved. To investigate the effect of high temperature on physical and mechanical properties of concrete, they were then exposed to 20, 100, 400, 700

When comparing the PCIBs with crushed sand stone, the replacement of crushed sand stone with concrete waste and marble waste results in lower physical and mechanical properties. By contrast, replacement of cement with fly ash (from 10% to 20%) has a significant effect in increasing important properties of PCIBs.
