Abstract A detailed feasibility study was performed to evaluate mining and transporting sand from the Mississippi River to restore Scofield Island, a rapidly-deteriorating barrier island in Plaquemines Parish, Louisiana. The proposed ecosystem restoration project includes reconstructing the beach and dune overtop the remaining …
Concrete is normally developed using river sand as fine aggregate. In this work, M30 grade of concrete has been developed by the mix proportion of 1:1.22:2.54 with water cement ratio 0.42. In this proportion, 1.22 parts of fine aggregate is partially replaced with sea sand. Concrete specimens were mould with 10%, 20%, 30% and 40% of sea …
3.3 Economic Feasibility Analysis The economic feasibility analysis is mainly made for cost-benefit analysis to quantify economic viability to manual sand and rock extraction from the Sari river. However, the economic feasibility analysis is established on the following stages and also given in the flow chart below: l.
River, and construction of a further 221 km road from Green River to Telefomin, including a 350m bridge over the Sepik River, to enable access to the mine site and proposed hydro-electric power station. • Establishment of a regional airport facility at Green River for commercial use, suitable for 50 seat fixed wing aircraft.
The Black River, as its name implies, is a slow moving, black water river with an average depth of 4 feet and width of 150 feet. Typically, the meandering streams in the Black River area have eroded through the unconsolidated superfi cial sands and clays into the older well-bedded sand and clay layers, forming deep valleys.
The majority of studies on using crushed sand as an alternative for some sand of river in concrete focuses on concrete grades up to M40. However, there is a dearth of material on HPC using higher grade concrete. This study delves into the utilization of crushed aggregate to supplant river sand, building upon the groundwork laid by prior ...

The novel SCPBs used in this study were prepared with Yellow River sand, fly ash, cement, admixtures, and water. The Yellow River sand was obtained from the shore of the Yellow River near the Zhaoguan Coal Mine in Dezhou, Shandong, while the fly ash was obtained from a thermal power plant near the mine.

This study aims to realize the resource regeneration application of copper tailing (as fine aggregates for partial replacement of natural fine aggregates), which avoid environmental pollution due to many landfills of copper tailings. The compressive strength and durability (dry shrinkage and sulfate attack) tests were carried out to evaluate the …
particles in river sand but M -sand possesses strong peaks of iron and calcium particles. River sand contains nitrogen, aluminium and potassium elements which are not present in M-sand. There are some regions which appear flattened showing less hydration process. A tangled web of flake-like crystal structure appears due to excess hydration process.
