Concrete is a hard substance made by mixing cement, sand, and small stones. The floor was made of solid concrete . Concrete is a composite construction material composed of cement, gravel…
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 …
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.
aggregate - material such as sand or gravel used with cement and water to make concrete, mortar, or plaster material, stuff - the tangible substance that goes into the makeup of a physical object; "coal is a hard black material"; "wheat is the stuff they use to make bread"
Definition: Aggregate is a granular material, such as sand, gravel, crushed stone, crushed hydraulic-cement concrete, or iron blast-furnace slag, used with a hydraulic cementing medium to produce either concrete or mortar.
Nominal mix concrete is prepared by approximate proportioning of cement, sand and aggregate to obtain target compressive strength. Mix ratio of concrete defines the ratio of cement sand and aggregate by volume in that order.

We have been given Grade – M15 and we have to calculate the quantity of cement, sand and aggregate in cft, cum and kg. Volume = 10 cubic meter (Now this is the Wet volume ) change it to dry volume. Dry Volume of Concrete. This is wet volume, so we need to convert it into dry volume.
Key points • 'Aggregate' is a term for any particulate material. It includes gravel, crushed stone, sand, slag, recycled concrete and geosynthetic aggregates.
Recycled concrete is a viable source of aggregate and has been satisfactorily used in granular subbases, soil-cement, and in new concrete. After harvesting, aggregate is processed: crushed, screened, and washed to obtain proper cleanliness and gradation.
Aggregate definition is - formed by the collection of units or particles into a body, mass, or amount : collective: such as. ... For example, it is used for a mass of minerals formed into a rock and for a material, such as sand or gravel, used to form concrete, mortar, or plaster. Examples of aggregate …
Professor Kamran M. Nemati Winter Quarter 2015 5 Concrete Technology Aggregates for Concrete Concrete Technology 9 Natural mineral aggregates, i.e., sand and gravel have a bulk density of 95 to 105 lbs/ft3 (1520 - 1680 kg/m3) and produce Normal- Weight concrete (NWC).
Construction sand and gravel, one of the most accessible natural resources and a major basic raw material, is used mostly ... sand used as aggregate in making concrete structures. The demand for concrete structures had increased at about the turn of the …
The sand and the aggregate help to reduce the cost and also limit the amount of shrinking that happens to the concrete as it cures. In order to produce a strong, resilient concrete mix, you need to get the ratio of aggregate to sand to cement right.
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 . Though people use the words cement and concrete as if they were the same, they're not.
Sand is one of the raw material of concrete (as fine aggregates). When sand is used as the bedding material, it must be compacted before the commencement of construction, then …
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.
In the aggregates industry, these rocks are classified as crushed stone, sand, gravel and slag. We use aggregates every day. Streets, bridges, roads and sidewalks are made of concrete or asphalt which is mostly made up of aggregates combined with a binder that acts like glue.

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 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.
