natural sand obtained from riverbeds as fine aggregate. However, due to the increased use of concrete in almost all types of construction works, the demand of natural or river sand has been increased. To meet this demand of construction industry excessive quarrying of sand from river beds is taking place causing the depletion of sand resources. The dwindling sand resources have not only posed ...
· The term "polymeric sand" might sound like some sort of hightech, futuristic product, but there's a good chance you've encountered it somewhere along the line.. It's a type of sand used to fill in the joints between pavers, a product that's created by mixing a fine sand with additives – typically silica – and water to form a binding agent that helps lock pavers together.
· You may use artificial grass underlay if laying onto a harder surface such as concrete or decking. Sharp sand paired with a weed membrane is the perfect combination when laying in your garden. In this blog, we will be looking over what goes under your artificial grass; different kinds of sand infill, artificial grass underlay and weed membranes, in order to help you make the best decision .
· Natural sand has an ideal shape for use as fine aggregate in concrete. The natural sand particles are wellrounded and are usually nearly spherical. Spherical particles decrease the percentage of voids within the concrete mixture so no additional paste is required to fill these voids. Wellshaped natural sands are ideal for workability of mixtures. Natural sand does not require more water to ...
natural river sand conforming to IS: was used as fine aggregate. Coarse aggregate . The size of aggregate bigger than is considered as coarse aggregate. It should be hard, strong, dense, durable, clean, and free from clay or loamy admixtures or quarry refuse or vegetable matter. The pieces of aggregates should be cubical, or rounded shaped. Coarse aggregates containing flat ...
· Global scarcity for natural sand: Injudicious sand mining and continuous depletion of natural aggregate sources have led to the implementation of new environmental/land use legislations which has made the procurement of natural sand difficult and expensive. Sand dredging is heavily taxed/ banned in many parts of the world. Growing demand for fineaggregates in construction: .
· Sand from deserts cannot be used for most purposes, as wind erosion over time forms round grains that do not bind well [4]. For most industrial uses, edged sand grains with a rough surface are needed, which stick together naturally. Desert sands, however, are usually fine grained and of low shear strength –it does not even suit as material ...
· We do not use use sea sand in construction due to following reasons Sea sand tends to very fine and rounded, Smooth rounded particles would offer less resistance to rearrangement than angular or elongated particles with rough surfaces. In sea water, chloride is present which will cause corrosion of steel and iron which ultimately leads.

· Sand is used as fine aggregate in concrete. Natural river sand is the most preferred choice as a fine aggregate material. River sand is a product of natural weathering of rocks over a period of millions of years. It is mined from the river beds and sand mining has disastrous environmental consequences. River sand is becoming a scarce commodity and hence exploring alternatives to it has .
· Clayey Sand This sand have prominent clay fraction and plastic fines. Traditionally used for the construction of walls Also used as mortar for bricks because of its high adhesive property 23. Use of sand in construction 1) Bricks work – Finest modulus of fine sand. The size of grains must be between – mm. it is formed by mixing clay ...
Sometimes natural sand is also used instead of crushed sand, to improve workability and reducing water requirement. The normal mix design is as difficult to use me the lightweight aggregate design because it has a high and rapid absorption property. But, by using waterproof coating like bitumen coating improve its property.
finegraded soils. 3. If a soil is a sand, the same steps and criteria are used as for gravels in order to determine whether the soil is a wellgraded clean sand (SW), poorlygraded clean sand (SP), sand with silty fines (SM) or sand with clayey fines (SC). 4. If a material is predominantly (>50% by weight) finegrained, it is classified into ...
· The sand is used as the fine aggregates for the purpose of concrete making. The gravel is another type of aggregates and is mainly used for as coarse aggregates in concrete. Bank gravel, bench gravel and crushed stone are the examples of gravel. The size of gravel ranges from 4mm to 64 mm. The gravels are also classified into different names based on their size.

Artifical sand is a kind of sand material produced by sandmaking equipment, such as impact crusher. Compared with natural river sand, artifical sand has the characteristics of sharp edges, many needles and flakes, and rough. River sand is directly excavated from the river, so it will be mixed with small pebbles and fine sand.
