River Sand is naturally occurring sand found in riverbeds or banks. It is typically well-rounded and composed of fine to medium-sized grains. River sand is widely used in construction, particularly in concrete production, plastering, and Masonry work. Beach sand is derived from coastal areas and is often a mix of minerals, including quartz, coral, shell fragments, and other organic materials. Beach sand is known for its fine particles and is commonly used in landscaping, sandboxes, and recreational areas. Pit sand is extracted from pits or quarries located on land. It is coarse-grained and often contains a mixture of various minerals. Pit sand is used in construction for applications like concrete works, filling trenches, and backfilling.

Natural sand is one of the coarse types of materials that are obtained from the depths of wells and are usually available in red and orange colors. In general, it can be stated that the appearance of these sands has a sharp and angular fracture and is used in concreting. River sands are obtained from rivers and have a much higher quality than sands obtained from pits. Their color is usually white to gray. Their appearance is completely round and without angles; Therefore, according to the mentioned features, this type of sand is used in plastering.

Fill sand, also known as utility sand or backfill sand, is typically used for filling voids, trenches, or low-lying areas. It is generally coarser in texture and may contain a mix of particles ranging from fine to coarse. In general, it can be acknowledged that synthetic sands are usually produced by crushing Granite or basalt Stones during three crushing stages and are a suitable alternative to river sands. These sands are produced in sand factories and by various Stone crushers. Also, from another point of view, artificial sand can be examined in smaller sections, which includes this type of material

• Natural sand: Natural sand is extracted from the river bed, alluviums and cones and after being washed, it is used in a variety of ways. Their shape is round and polished.
• Broken sand: These sands are coarse and usually broken. Available in corner form.
• Washed sand: There are large amounts of soil and organic materials among the sands, which affect the efficiency of the sand, for this reason, it is washed and separates the sand from those materials.
• Light-grained sand: Sands such as pumice, tuff, clay, shale, diatomite and volcanic ash, which have low density, are called light-grained sand.
• Ordinary sand: The sand that exists around us naturally is called ordinary sand. This type of sand can be used to make concrete with normal weight.
• Heavy grain sand: grains such as serpentine, magnetite, ilmenite, geotite, limonite and barite are called heavy grain sands, which can be used to make heavy weight concrete.
• Natural sand: This type is naturally extracted from the sea and river bed.
• Washed sand: This type of sand is also called double salt, which is a mixture of sand and soil.
• Broken sand: this type has a sharp appearance and is obtained from the grinding of mineral stones.
• Round sand: As their name suggests, these sands have a round and spherical appearance. They are also artificial sand.
• Angled sand: This sand has high strength and the porosity between them is less than round sand.
• Semi-round sand: These grains do not have a completely round appearance, and some are round and some are angular.
• Mixed sand: this type of sand does not have a special shape.

Crushed stone sand, also known as M-Sand, is produced by crushing larger stones or Rocks into smaller particles. M-Sand has angular grains and is free from organic and silt content. It is widely used in concrete production, plastering, and as a substitute for river sand in construction. Silica sand consists mainly of silicon dioxide (SiO2) and is characterized by its high silica content. It has a wide range of industrial applications, including Glass manufacturing, foundry casting, ceramics, filtration systems, and hydraulic fracturing in the oil and gas industry. Desert sand refers to the sand found in arid regions like deserts. Unlike other types of sand, desert sand is not suitable for construction due to its rounded grains and lack of cohesion. The grains are often too smooth, making desert sand less stable for structural applications.
