Use of Reservoir Sediments to Improve Engineering Properties of Dune Sand in Oman

Managing sediments dredged from reservoirs of recharge dams is an environmental issue, however, these can be abundant and economical source fine-grained fill soil. This experimental investigation quantifies the geotechnical properties a reservoir sediment used to improve engineering poorly graded dune sand in Oman. The binary mixes were prepared with different percentages (5, 10, 20, 50, 75, 90, 95%) sand. Laboratory tests such as gradation, consistency limits, compaction, unconfined compression performed measure characteristics mixtures. results showed that maximum dry density increases up content 50% then decreases further increase content. optimum water 17% for pure 22.5% sediment. moisture shows good correlation plastic limit mixture compressive strength substantially 75% sensitive moisture, order stability against mixed 20% sediments. addition improved uniformity coefficient some extent minimum void ratios well. elemental analysis confirms material non-contaminated employed applications sustainable environmentally friendly solution.
