Abstract: This paper aims to focus on the possibilities of using waste materials from different
manufacturing activities in the preparation of innovative mortar and concrete. Two kinds of
waste were identified: marble sludge from marble processing, and cement kiln dust. The use
of this waste was proposed in different percentages both as an addition to and instead of
cement, for the production of Self Levelling Mortar. Two mixtures containing natural
aggregates were also prepared for comparison purposes, one using limestone powder as a
mineral addition and the other with no addition. A total of sixteen different mixtures were
prepared containing 10, 20 and 30% waste compared to the total quantity of aggregates and
10, 15 and 20% compared to the amount of cement. The two residues were characterised from
a chemical, physical and morphological point of view. The prepared mixtures were then
studied in terms of their properties both in fresh and in hardened state. In particular, tests were
conducted on the mortars cured at different times in order to determine their flexural and
compressive strength, water absorption and capillary absorption.
