Performance of cement mortars prepared by replacing 30% and 60% of crushed calcareous fine aggregate (CNA) with waste fine aggregates namely, crushed brick aggregate (CBA), crushed marble aggregate (CMA) and crushed ceramic aggregate (CCA) is investigated. For this purpose, absorption, unit weight, compressive strength, flexural strength, modulus of elasticity, capillarity, drying shrinkage, resistance to high temperature up to 400 degrees C and resistance to freeze-thaw cycles are determined. In addition, X-ray flourescence (XRF) and X-ray diffraction (XRD) are performed on cement and aggregates and scanning electron microscopy (SEM) analysis is conducted on mortars in order to examine their mineralogy and morphology. It is found from the experimental results that CBA mortars exhibited the lowest strength values and the worst durability properties. However, CBA and CCA mortars are more effective in relative strength gain at 56 days. Residual strength values of CCA and CMA mortars after freze-thaw and high temperature resistance tests are higher than those of other mortars.
