This research presents an attempt of using wastewater from slurry waste of stone cutting plants in production of cast
stone. Several mixes that can be used in producing cast stone were prepared by using tap water and stone slurry
wastewater at different replacement ratios of wastewater in substitute of tap water. Different samples were tested to
measure the slump of fresh cast stone mix and compressive strength and absorption of hardened cast stone samples.
Two water cement ratios were used 0.6 and 0.7 and four different percentages of replaced water were used 0%, 20%,
and 100% for each w/c ratio.
The revealed results of the tested samples showed that although the slump of fresh mixes was reduced, the
compressive strength of the hardened samples was not affected much. The absorption increased by using slurry
wastewater at different ratios. The expected outcome of this research is reduction of using tap water in producing
cast stone. Substantial amount of fresh water consumed by the growing cast stone industry in Palestine will be conserved for domestic use
