Effluent from RO (Reverse Osmosis) systems during recovery gradually becomes concentrated and supersaturated with soluble salts such as calcium carbonate (CaCO3), calcium sulfate (CaSO4), barium sulfate (BaSO4) and silica ...

The benefits of using mineral admixtures as a partial replacement of portland cement (PC) are well established in the literature. Economic and environmental advantages by reducing CO2 emissions are well known. This paper ...

Open-channel junctions have a broad application in civil and environmental engineering. Formation of a low-pressure zone with recirculating flow (high sedimentation) accompanied by a high-velocity zone (high erosion) is ...

In this paper, the effect on the strength properties of high strength concrete (HSC) manufactured with silica fume (SF) and ground pumice (GP) is investigated. Portland cement was replaced with SF, GP and combination of ...

In the current study an experimental/statistical approach addressing key mechanical properties (compressive, tensile and flexural strength) and impact resistance of such new fibers with inclusion of different volume of ...

Throughout history dams have been important structures in water storage. To avoid overtopping, damage, and or failure of a dam, adequate spillway is needed to release excess water from upstream floods. Researchers found ...

The electro-osmotic consolidation is a method to improve geotechnical properties of soft clayey soils. The feasibility of electro–osmotically induced consolidation can be examined through the soil coefficient of electro–osmotic ...

Natural frequency is one of the parameters that represent useful information about the dynamic behavior of structures. Controlling this parameter can decrease the probability of damage under dynamic loading. Weight ...

Soil slopes are sometimes curved in plan rather than being straight. This curvature,especially when it is convex, decreases the bearing capacity of the slope. Finite element methodhas been used here in this research to ...
