The physicochemical 12 parameters, the type of rocks and soils present along the river determine the chemical composition of the sediments1. The physical and chemical properties depend on the physical topography, climate, temperature, vegetation and microbial activities 2,3. Generally sand .
The chemical composition of the soil, the topography, and the presence of living organisms determines the quality of soil. In general, soil contains 4045% inorganic matter, 5% organic matter, 25% water, and 25% air. In order to sustain plant life, the proper mix of air, water, minerals, and organic material is .
It feeds the large valley of Veria and has a total length of 314 km. The chemical analysis of the sand from the Aliakmon river is given in the following Table 6 : Table 6: Chemical analyses of the Aliakmon river A comprehensive research work was carried out concerning the physical and chemical properties of the river sands.

Properties of Desert Sand and CMAS Glass Narottam P. Bansal National Aeronautics and Space Administration Glenn Research Center Cleveland, Ohio 44135 Sung R. Choi Naval Air Systems Command Patuxent River, Maryland 20670 Abstract Asreceived desert sand from a Middle East country has been characterized for its phase composition
of oxygen resulting in the chemical formula SiO 2 Sand consists of small grains or particles of mineral and rock fragments. Although these grains may be of any mineral composition, the dominant component of sand is the mineral quartz, which is composed of silica .
Feb 22, 2011· The sand composition depends directly on its origins. As an example, sands collected from volcanic islands often have in their composition volcanic tuffs and ashes while the beaches of single atolls are usually made of corals and skeletal remains of tiny sea animals.
This paper is centered on the characterization of some beach/river sand, with a view to determining the chemical composition, moisture content, grain shape and distribution, AFS clay content, refractoriness, permeability, and green compression strength. Material and Method
Silt Clay Mud Sand Soil: What Is The Difference? Silt is granular material of a size somewhere between sand and clay whose mineral origin is quartz (made up of a continuous framework of SiO4 silicon–oxygen tetredra, with each oxygen being shared between two tetredra, giving an overall formula SiO2) and feldspar ( KAlSi3O8 – NaAlSi3O8 – CaAl2Si2O8).

The most common constituent of sand, in inland continental settings and nontropical coastal settings, is silica (silicon dioxide, or SiO 2), usually in the form of quartz, which, because of its chemical inertness and considerable hardness, is the most common mineral resistant to weathering.. The composition of mineral sand is highly variable, depending on the local rock sources and conditions.
The smoothness and color of river pebbles depends on several factors, such as the composition of the soil of the river banks, the chemical characteristics of the water, and the speed of the current. Because river current is gentler than the ocean waves, river pebbles are usually not as smooth as beach pebbles. The most common colors of river ...
Chemical Properties. Spent foundry sand consists primarily of silica sand, coated with a thin film of burnt carbon, residual binder (bentonite, sea coal, resins) and dust. Table 72 lists the chemical composition of a typical sample of spent foundry sand as determined by xray fluorescence.
