Abstract

The article presents the results of chemical composition and selected properties of the fly ash (FA) and sewage sludge ash (SSA) from the disposal of sewage sludge. The results of research on sewage sludge ash (SSA) and fly ash (FA) and the effect of these ashes on properties of fresh pastes have been presented. By means of XRD analysis, the occurrence of crystalline materials was detected. By means of SEM the morphology of ashes and cement pastes with ashes was investigated. The phase of the C-S-H mortars with addition of sewage sludge ash and fly ash is fairly compact. They performed the testing of compressive strength of mortars after 28 and 90 days of maturation.

Keywords:
