This test method covers determination of the density of freshly mixed concrete and gives formulas for calculating the unit weight, yield or relative yield, cement content, and air content of the concrete. Yield is defined as the volume of concrete produced from a mixture of known quantities of the ...

Concrete Calculator. The Concrete Calculator estimates the volume and weight of concrete necessary to cover a given area. It also estimates the number of bags of concrete necessary based on standard 60 and 80– pound bags of concrete.

Concrete is not a chemical composition and hence no standard unit weight can be defined. Weight of Bricks and aggregates vary widely. The values provided are only indicative. Density of coarse and fine aggregates vary with the level of compaction.

Unit Weight. The unit weight of asphalt concrete is equal to the weight of a given sample divided by its volume. Unit weight is just another way to measure density ...

The unit weight of reinforced concrete for both dead load and modulus of elasticity shall be taken as 160 pcf for all structural analysis, except as approved by the Bridge Design Engineer for unique designs (like floating bridges).

A concrete masonry unit (CMU) is a standard size rectangular block used in building construction. Those that use cinders (fly ash or bottom ash) are called cinder blocks in the United States, breeze blocks (breeze is a synonym of ash) in the United Kingdom, and hollow blocks in the Philippines.

An educational, fair use website. Concrete is an artificial material similar to stone that is used for many different structural purposes. It is made by mixing ...

Concrete weighs about 150 pounds per cubic foot. This is a design figure, and it is subject to some variation. That translates to just over 2400 kilograms per cubic metre (2400kg/m3) or 24 kilonewtons per cubic metre (24 kN/m3 ...

In USCS units (United States Customary System units), its weight comes to ~150lb/ft 3 and ~2,400 kg/m 3 if measured in Metric SI system. The concrete converter can be applied in construction and structural engineering for exchange from volumes of concrete quantities into their equivalents in mass. Extensive list of
