Manufactured proppants provide a wide selection of grain size and specific gravity compared to a natural proppant known as frac sand. Frac sand is currently used instead of manufactured proppants because it has a cost and transportation advantage.
Sandstone is a sedimentary rock composed of sand-size grains of mineral, rock, or organic material. It also contains a cementing material that binds the sand grains together and may contain a matrix of silt- or clay-size particles that occupy the spaces between the sand grains.
Sand & gravel is a naturally occurring mineral complex that contains varying quantities of quartz (crystalline silica). In its natural bulk state, sand & gravel is not a known health hazard. Sand & gravel may be subjected to various natural or mechanical forces that produce small particles (dust)

natural aggregate deposits, called pit-run gravel, consist of gravel and sand that can be readily used in concrete after minimal processing. Natural gravel and sand are usually dug or dredged from a pit, river, lake, or seabed. Crushed stone is produced by crushing quarry rock, boul-ders, cobbles, or large-size gravel. Crushed air-cooled

Natural sand are weathered and worn out particles of rocks and are of various grades or size depending on the accounting of wearing. The main natural and cheapest resource of sand is river.
A dense graded base aggregate, produced by screening and crushing, natural sand & gravel. A material formed by the natural abrasion and disintegration of rocks by glacial or riverbed action. The particles are sized from 1″ (25.0mm) to zero (dust).
Shape comparison between natural sand proppants and ceramic proppants. There are two clearly different ranges of Aspect Ratio ( Krumbein’s Sphericity ). Analysis of other shape parameters are possible as well (Convexity for ceramic bead
Masonry sand has a maximum particle size of 3/16 inch (4.75 mm), which could mean that it is a nearly ideal sand for many base coats, and particularly for lime and cement-lime body coats which are typically applied at a depth of about 3/8 inch.
Sand is a granular material composed of finely divided rock and mineral particles. It is defined by size, being finer than gravel and coarser than silt. Sand can also refer to a textural class of soil or soil type; i.e., a soil containing more than 85 percent sand-sized particles by mass.
What is Silica Sand? Image of Silica Sand close up ... The natural grain shape and controlled particle size distribution of silica provides the required permeability and compaction properties for drainage, healthy plant growth, and stability. ... different frac sand mesh size ranges are required. 20/40 are typically used in hydraulic fracturing ...
The natural sand deposits are getting depleted by continuous digging causing damage to the environment in many ways. As the supply of suitable natural sand near the point of consumption is becoming exhausted, the shortage of good natural sand for concrete production is facing challenges.
River/Natural Sand: River Sand is usually obtained from River Beds and Banks. It is usually very fine in quality and has a white-grey color. River Sand is good for all construction activities like concrete production and plastering as it is well graded.
Chapter 26 Gradation Design of Sand and Gravel Filters Part 633 National Engineering Handbook 633.2600 Purpose Chapter 26 presents criteria for determining the grain-size distribution (gradation) of sand and gravel filters needed to prevent internal erosion or piping of soil in embankments or foundations of hydraulic structures.

Media with small grain size slow the water movement and increase the chance of clogging. The effective size (D 10) and uniformity coefficient (Uc) are the principal characteristics of granular media treatment systems. The ideal sand media for intermittent sand filters is a coarse sand with an effective size between 0.3 mm and 0.5 mm.
• Natural sands contain enough naturally occurring clays that they can be mixed with water and used for sand molding. • Synthetic sands have been washed to remove clay and other impurities, carefully screened and classified to give a desired size distribution, and then reblended
Grain size (or particle size) is the diameter of individual grains of sediment, or the lithified particles in clastic rocks. The term may also be applied to other granular materials. This is different from the crystallite size, which refers to the size of a single crystal inside a particle or grain.
