This research empirically investigated the impact of mixing water quality on the properties of concrete. The water was collected of different qualities and sources from different locations in the Gaza strip. The TDS concentration in the mixing water was of arranging between 640(mg/l) to 35000(mg/l). 36 concrete cubes were produced at a ratio of 1: cement, 2: sand, 4: aggregate, 0.5: w/c using different TDS concentrations. The cubes were cured and crushed at 7, 14 and 28 days to measure the compressive strength. It was observed that the concrete produced with saltwater had their compressive strengths gradually increased (21.64, 23.18 and 30.35) % of freshwater in (7, 14 and 28 days) respectively. In addition, the setting time is decreasing with increasing the content of TDS. The setting time of seawater decreases by about 23.07% of freshwater. It is noticed that there are no problems to mix the concrete with saltwater with high TDS.
