Sand mining is a practice, that is used to excerpt sand, mainly from quarry/ open pit. Sand is extracted from beaches, inland dunes, and mined from ocean beds and river beds. The excessive mining of river bed, to encounter the increasing demand for sand in construction industry, has led to the ecological imbalance in nation. Environmentalists
Ab stra ct² T he present study is aimed to utilize Waste marble powder and quarry sand as partial replacement of cement and comparing it with conventional concrete. This experimental investigation is carried out by M 30 grade of concrete is produced by replacing cement with 0%, 10%, 20% & 30% of Marble Powder & Quarry dust.
It is recommended to use crushed sand. It is an economic and ecological alternative to natural sand. Crushed sand possesses properties similar to that of river and is a more sustainable construction material. Scientifically use of crushed sand will provide a long-term solution to construction industry to overcome shortage of river sand.
Sand (M-Sand) and Quarry Dust Sand as a substitute for river sand become inevitable. To overcome from this crisis, fully replacement of sand with M-Sand and Quarry Dust can be an economic alternative. In this project determine the concrete's strength and durability by using M-Sand and Quarry …
While course, gritty construction-grade sand is stripped from beaches and river beds, desert sand has remained an untapped resource as its wind-swept grains are …

Quarry dust has been proposed as an alternative to river sand that gives additional benefit to cement during construction. In areas where constructors use this dust, there is a significant reduction of air pollution by the dust.
Request PDF | Pertinence of alternative fine aggregates for concrete and mortar: a brief review on river sand substitutions | Construction industries around the world are facing many difficulties ...
Alternative sand can be classified as crushed rock sand (CRS), recycled fine aggregates (RFA), and industrial by-products. Alternative sand or manufactured sand is made from other than natural sources, by processing materials, using thermal or other processes such as …
Some alternative materials, such as fly ash, copper slag, limestone, and siliceous stone powder, are also used as a partial or full replacement of river sand in the production of mortar and ...
This sand is very much useful for construction purpose such as plastering and so on. Crushed Stone Sand/ Artificial Sand/ M Sand. It is a substitute for River Sand, it is also known as fine aggregates which are manufactured by crushing either granite or basalt rock using 3 stage crushing process by some companies.
quarry waste powder by replacing the cement content[21]. In construction industry, enormous utilization of natural river sand was making them to scarce and cause environmental issues like erosion, soil infertility. Currently, many researchers were searching for the effective material for replacing the river sand[22][23].
crushed sand can be mitigated by using a water reducing admixture. R. Ilangovana et al. [6] found that the natural river sand, if replaced by hundred percent quarry rock dust from quarries, may sometimes give equal or better than the reference concrete made with Natural Sand, in terms of compressive and flexural strength studies.
of river sand mining. In the future the entire construction industry may come to a halt if there are no alternatives for river sand. Therefore, it is necessary to explore possible alternatives to minimize the use of river sand. At present the identified alternatives are dune sand, offshore sand, manufactured sand (crushed rock sand) and quarry ...
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. As per the Indian Standard codes, sand used in preparation of concrete and in plastering should ideally confirm to IS-383 Zone-II.
How Silica Sand Is Different From Regular Sand. Regular sand, also known as feldspathic sand, brown sand, or construction sand, will always contain some silica, but only in amounts less than 95%. For example, typical brown sand used for concrete applications can contain up to 80% SiO2, along with varying amounts of iron, carbonate, potassium ...
