Abstract:   Mosaic tile is considered as one of the most popular tiles used as finishing material in different parts of the buildings, especially, for floor finishing. During the process of the manufactured mosaic tile, a huge volume of sludge waste has been produced in the stage of polishing and has the effect towards the environment, so it can be reused as a partial replacement of cement for economical purpose. The mosaic sludge can be improved to the mosaic powder through the process of normally drying and sieving. In this paper, an experiment has been conducted to investigate the behavior of compression strength of the concrete by replacing cement with the mosaic tile dust (MTD) by the rate of 5%, 10%, 15%, 20%, 25% and 30%. For this purpose, an experimental program was carried out in which fourteen mixes with different combinations of mosaic tile dust in two different groups of different w/c ratio of 0.45 and 0.55 respectively. The samples are tested and compared with the conventional concrete to find out whether the compressive strength increases or decreases with increasing the rate of replacing the cement by mosaic tile dust (MTD) by the above ratios.
