Impact of glass and ceramic waste on selected properties of materials with a cement

The article presents the impact of selected waste materials (usable ceramics, sanitary ceramics, CRT glass cullet) on the physical and mechanical properties of cement-based materials (cement mortars). The samples of cement mortars made were 10, 20 and 30% addition of waste material. Physical and mechanical properties of modified cement mortars were compared with standard mortar. The highest compressive strength obtained mortar with the addition of usable and sanitary ceramics in the amount of 30%. The mortar was also characterized by the lowest decreases in compressive strength after frost resistance tests. The use of 30% sanitary ceramics resulted a compressive strength drop of 3.5% compared to 18% for the standard mortar. The absorbability of all samples differed slightly.
