Concrete is made up of three basic components: water, aggregate (rock, sand, or gravel) and Portland cement. Cement, usually in powder form, acts as a binding agent when mixed with water and aggregates. This combination, or concrete mix, will be poured and harden into the durable material with which we are all familiar.

Concrete Ingredients Calculation. For Cement, Sand and Coarse Aggregate. This is a Volumetric Calculation. Assuming we need 2 m 3 of concrete for M20 Concrete Mix, (Mix Ratio, M20 = 1 : 1.5 : 3) Total Part of the Concrete = 1+1.5+3 = 5.5 Parts. Therefore, Cement Quantity = (Cement Part / Concrete Parts ) * Concrete Volume

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.

Concrete is a construction material composed of cement, fine aggregates (sand) and coarse aggregates mixed with water which hardens with time. Portland cement is the commonly used type of cement for production of concrete. Concrete technology deals with study of properties of concrete and its practical applications.

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.

Only cement is unusually used; it is used to bind coarse and fine aggregate to produce mortar and concrete. The cement is mixed with fine aggregate to have mortar for plaster and masonry, and with sand and coarse aggregate to give concrete.. As I said, earlier density is the material’s mass per unit volume.

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.

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.

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

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.

In cement, gravel and sand together provide the right support when the mix hardens. The materials in asphalt provide a similar role. Aggregate may be combined with other materials to produce concrete. Aggregates find there way into several applications. For example, gravel is used to pave some road types and provides support for railroad tracks.

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.
