In this study, it is aimed to reduce the density of the screed mortar and increase the heat and sound performance of the screed by using expanded glass aggregate and expanded perlite aggregate in screed mortar which is mainly used for surface coating and leveling in the construction sector. To achieve this objective, the most common four cement types in the construction industry were used, and expanded glass aggregates (0.25-0.5 mm) and expanded perlite aggregates (0.25-0.5mm) were replaced with CEN standard sand as the ratio of 0%, 15% and 30%. The density, heat and sound insulation performance properties of the substituted screed samples obtained were obtained through experiments. In these experiments, screed mortars were produced in accordance with TS EN 13892-1 standard, and tests concerning compressive strength, bending strength and wearing resistance, which were required to be determined in cement-based screed mortars according to TS EN 13813 standard were performed. In the light of the study; expanded glass aggregates and expanded perlite aggregates were used to obtain screed mortar with the strength range between 17.60 MPa and 58.00 MPa, bending strength range between 4.00 MPa and 11.16 MPa, wearing resistance range between 9.22 cm3/50cm2 and 17.26 cm3/ 50cm2, density range between 1.669 g/cm3 and 2.192 g/cm3, sound absorption range between 0.151 and 0.249, thermal conductivity range between 0.446 W/mK and 0.817 W/mK, and the related parameters were examined.
