Concrete is that pourable mix of cement, water, sand, and gravel that hardens into a super-strong building material. Sidewalks, foundations, and highways are all made 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.
As specified in the question the grade of the concrete is M15 so the mix ratio of the constituent material will be: 1: 2: 4 (cement: sand: aggregates) {Grades of concrete are defined as the concrete mix proportion of cement, sand and aggregates also it defines the minimum strength of concrete at end of 28 days curing}.

Coarse aggregates are particulates that are greater than 9.5mm. The usual range employed is between 9.5mm and 37.5mm in diameter. Typically the most common size of aggregate used in construction is 20mm. A larger size, 40mm, is more common in mass concrete. Larger aggregate diameters reduce the quantity of cement and water needed because of its
Is Concrete A Ceramic 2. Concrete is a ceramic composite made up of water, sand, gravel, crushed stone, and cement. The ingredients are mixed together thoroughly, and are poured into a form. After the concrete is completely dry, it has excellent compressive strength.
The aggregates are sand and gravel or crushed stone; the paste is water and portland cement. Concrete gets stronger as it gets older. Portland cement is not a brand name, but the generic term for the type of cement used in virtually all concrete, just as stainless is a type of steel and sterling a type of silver.

Aggregates for Concrete bination of gravels or crushed stone with particles predominantly larger than 5 mm (0.2 in.) and generally between 9.5 mm and 37.5 mm (3⁄ 8 in. and 11⁄ 2 in.). Some natural aggregate deposits, called pit-run gravel, consist of gravel and sand that can be readily used in concrete after minimal processing. Natural
Aggregate
''Cement'' vs. ''Concrete'' This distinction is not a new one; we have citations from over a century ago in which writers take care to observe (or admonish) that concrete and cement are not synonymous (the reasoning being that cement is one of the parts of concrete).. But cement is not concrete, so another trial was made, by forming blocks of the latter material 14 inches long, 4 inches wide, and
Calculating the aggregate quantity, Get the part of aggregate content in the concrete mix from the grade specified in fraction from. (Example, part of cement in grade M15 is 4/7 as ratio is 1:2:4). Multiply the same with the required dry volume of the concrete you will get the aggregate required in volume which has to be converted to weight.
Cement definition, any of various calcined mixtures of clay and limestone, usually mixed with water and sand, gravel, etc., to form concrete, that are used as a building material. See more.
Definition: Aggregate is a granular material used in concrete and mortar.It usually comes from natural river sand and river pebbles, or from crushed natural rocks. Such as sand, crushed stone and gravel. It is one of the main components of concrete and acts as a filler for concrete, not only giving them quality, but also providing strength and durability.
Hydraulic cement concrete is a cement and water paste in which aggregate particles are embedded. Aggregate is granular material such as sand, gravel, crushed stone, blast-furnace slag, and lightweight aggregates that usually occupies approxi-mately 60 to 75% of the volume of concrete. Aggregate properties significantly affect the workability of
Definition. A concrete made from a mixture of lime, sand, and gravel is said to be as lime concrete. It was widely used before the lime was replaced by Portland cement. Lime as the first cement: Since long, Lime has been used to make things like plaster and mortar. Lime is usually made by burning of limestone.
High Strength Concrete— M60 M65 M70 M75 M80 High performance concrete— M 90, M95 M100, M105, M110, M115, M120. Concrete mix can be classified as 1. Nominal mix & 2. Design mix. 1. Nominal mix: Nominal mix specifies the proportion of the cement , sand and aggregates without making special effort to know their individual properties.
Concrete Aggregates – Function, Properties, Characteristics and Significance. Aggregate is a granular material, such as sand, gravel, crushed stone used with a cement to produce either concrete or mortar. Aggregate is relatively inexpensive and does not enter into complex chemical reactions with water; it has been customary, therefore, to
Mary McMahon. Date: January 29, 2022. Wet concrete being poured. Concrete aggregate is a material which is mixed with cement to create concrete which is hard, strong, and long-lasting. There are a number of different types of concrete aggregate, with contractors selecting their aggregate on the basis of the type of job being performed.
Aggregates Definition: Aggregates are coarse particulate rock-like material consisting of a collection of particles ranging in size from < 0.1 mm to > 50 mm. It includes gravel, crushed rock, sand, recycled concrete, slag, and synthetic aggregate. Aggregate is a granular material, such as sand,
Is Concrete A Ceramic 2. Concrete is a ceramic composite made up of water, sand, gravel, crushed stone, and cement. The ingredients are mixed together thoroughly, and are poured into a form. After the concrete is completely dry, it has excellent compressive strength.
Introduction. Sand and gravel are used extensively in construction. In the preparation of concrete, for each tonne of cement, the building industry needs about six to seven times more tonnes of sand and gravel (USGS, 2013b). Thus, the world’s use of aggregates for concrete can be estimated at 25.9 billion to 29.6 billion tonnes a year for 2012 alone.
Solution: In case of M10 concrete, the ratio of cement, sand and aggregate is 1 : 3 : 6. Dry volume of concrete = wet volume of concrete × 1.54. Hence, the dry volume of concrete is = 3 × 1.54 = 4.62 m 3. The required quantity of cement is = (Cement ratio ÷ Sum of all ratio) × Total volume of concrete = = 0.462m 3.
Cement, sand, aggregates and water are the components of concrete. A mixture of Portland cement and water is called a pasta. So, concrete can be described as a mixture of paste, sand, and aggregates, although sometimes rocks are used in place of aggregates. The cement paste coats the surface of the fine and coarse aggregates when mixed

Multiply the same with the required dry volume of the concrete you will get the aggregate required in volume which has to be converted to weight.

Natural aggregate consists of manufactured crushed stone and sand created by crushing bedrock, or naturally occurring unconsolidated sand and gravel. It is a major component of asphalt and concrete and is required in streets, highways, railroads, bridges, buildings, sidewalks, sewers, power plants, and dams—just about every part of the built environment.
Concrete is defined as a mixture of cement sand, gravel and water which dries hard and strong and is used as a material Dictionary Thesaurus Sentences The definition of concrete is something real. An example of concrete is evidence that the world is not flat.
