dc.description.abstract	The performance of two groups of mortar mixes containing Unprocessed Fly Ash (u-FA) with either Raw Sewage Sludge (RSS) or water was examined. Both groups included four mortar mixes containing Portland cement, sand, u-FA. Group 1 used RSS as a water replacement and Group 2 used water. Cement was replaced with 0, 10, 20 and 30% u-FA of total binder weight and one Liquid/Binder ratio of 0.8 was used. Mortar mixes were tested for their flowability, Total Water Absorption (TWA), Ultrasonic Pulse Velocity (UPV), compressive strength and drying shrinkage. The outcomes of the investigation were encouraging in that cement-based materials containing RSS demonstrated good engineering properties in comparison to the control mixes. The inclusion of u-FA significantly reduced flowability; however improved long-term compressive strength for both groups. The greatest compressive strength was recorded for the mixes with 10–20% u-FA replacement.
