Apparent consumption also increased to about 1.01 billion tons. Consumption of construction sand and gravel was higher in 2016 because of increased consumption during every quarter since the second quarter of 2013, with an average increase of 6 percent over the same period of the previous year.

Concrete Mix Design:-Concrete is a composite mixture which consists of Cement, Sand and Aggregate. Concrete mix design is the procedure for finding the right quantities of these materials to achieve the desired strength.
When it comes to binding a plane surface to concrete surface, the ideal mix of cement to sand is 1:4. The thickness of the mortar may vary from 2.5 cm to 4 cm while providing a slope to the floor. White cement or putty should be applied to the joints of the tiles.
Sand has by now become the most widely consumed natural resource on the planet after fresh water.  The annual world consumption of sand is estimated to be 15 billion tons, with a respective trade volume of 70 billion dollars. Over the last two centuries sand has …
Concrete is a material comprised of a number of coarse aggregates (particulate materials such as sand, gravel, crushed stone, and slag) bonded with cement. Cement is a substance that is used to bind materials, such as aggregate, by adhering to said materials, then hardening over time. While there ...
Construction aggregate, or simply "aggregate", is a broad category of coarse to medium grained particulate material used in construction, including sand, gravel, crushed stone, slag, recycled concrete and geosynthetic aggregates. Aggregates are the most mined materials in the world.
Concrete rubble should be recycled to avoid using aggregates, at least for low-quality uses. Recycling glass bottles would also reduce sand consumption. Also, substitutes for sand are available. Quarry dust could be used to replace sand in general concrete structures.
Reducing consumption of sand. One way to reduce consumption of sand is to optimise the use of existing buildings and infrastructure. Recycled building and quarry dust material can be a substitute for sand. Despite the very high value of minerals found in the sand, it is mostly used for concrete or is buried under highways.

Density of concrete = 2500kg/m3. Let's assume you need to mix for 1m3 of this concrete. So, total quantity of concrete is 2500kg. Your proportions are 1:5:10. Summing up, that is 16. So one part cement would mean. 1/16 *2500 = 156.25kg of cement per cubic metre of concrete…
Example calculation Estimate the quantity of cement, sand and stone aggregate required for 1 cubic meter of 1:2:4 concrete mix. Ans. Materials required are 7 nos. of 50 kg bag of cement, 0.42 m 3 of sand and 0.83 m 3 of stone aggregate.
To address the issue of sand scarcity, Holcim is exploring the potential of manufactured sand - or 'M-sand' - for use in concrete. M-sand is a term used to describe fine aggregates produced by crushing stone using specialised equipment, or generated as a byproduct of the production of coarse aggregates.
Calculation Of Materials For Different Mix Ratio: Quantity estimation of materials is essentially required in any construction works and quantity of materials depend on the mix proportions of the concrete. In our previous article, we have already discussed how to calculate bricks in a wall.
Concrete Mix Design Calculation for M20, M25, M30 Concrete with Procedure & Example Concrete mix design is the process of finding right proportions of cement, sand and aggregates for concrete to achieve target strength in structures.
How to Calculate Quantities of Cement, Sand and Aggregate for Nominal Concrete Mix (1:2:4)? Mix design is a process of determining the right quality materials and their relative proportions to prepare concrete of desired properties like workability, strength, setting time and durability.
Concrete and glass are made mostly of sand, a certain type of sand found deep below the earth's surface, underwater, and on beaches. Sand mining to meet increasing demand over the years has become a thriving multibillion-dollar industry, but research by the United Nations Environment Programme (UNEP) shows that rate to be unsustainable.
increase compared with the apparent consumption in 2014. of the 885 Mt of construction sand and gravel produced for consumption, 68% was reported or estimated without a breakdown by end use (table 5). of the remaining construction sand and gravel produced for consumption, 45% was used as concrete aggregate; 23% was used for road base and coverings;
Following is a simple method used by engineers to calculate cement, sand and aggregate to produce different grade of concrete like M5, M7.5, M10, M15 and M20. if you don't want to learn the math involved in the design, you can use the table given at the end of the article to produce different grade of concrete.

Natural gravel and sand are usually dug or dredged from a pit, river, lake, or seabed. Crushed aggregate is produced by crushing quarry rock, boulders, cobbles, or large-size gravel. Recycled concrete is a viable source of aggregate and has been satisfactorily used in granular subbases, soil-cement, and in new concrete.
