Density (Unit weight) of Concrete Bulk Density Concrete, an artificial stone-like mass, is the composite material that is created by mixing binding material (cement or lime) along with the aggregate (sand, gravel, stone, brick chips, etc.), water, admixtures, etc in specific proportions.
A typical concrete mix weighs 150 lbs per cubic foot, 4,050 lbs per cubic yard, or 2,400 kg per cubic meter. The weight of concrete is determined by its density, which can vary based on the amount of aggregate, water, and air in the mix.
For the hypothetical project referenced in Figure 1, if the total cost of the concrete masonry units is $90,000, the recycled content value of the concrete masonry units is 0.365($90,000) = $32,805. It is important to note that the cost used in this calculation is the amount paid to
Further, unit weight of concrete made with CBA is also affected by the use of WRAs. The experimental study by Ghafoori and Bucholc (1996) confirms this phenomena and shows increase in unit weight of concrete incorporating 100% CBA by an average of 0.8% on use of low dosage of 370 mL per 45 kg cement and an additional 0.25% when high admixture
As specified in the definition of certain concrete types per ACI 318-14, clause 2.3, there is a correlation between the concrete types and the unit densities. The unit densities are specified explicitly for lightweight concrete as between 90 and 115 lb/ft3 and normalweight concrete as between 135 and 160 lb/ft3. The unit density information for
The unit weight of unreinforced concrete measured by the WSDOT materials Lab shows that 212 sets out of 10561 sets of cylinders tested exceeded 155 pcf. Considering the additional weight of reinforcement steel and increased use of High Performance Concrete (HPC) with higher density, it is appropriate to use 160 pcf for the unit weight of concrete.
Concrete mix designs are all slightly different but in general terms, concrete weighs 150 lbs (pounds) per 1 cubic foot. The actual weight of the concrete is determined by its density which will increase or decrease a little depending on aggregate, water, cement, and air used to make the concrete mixture.

The unit weight is determined by the formula below. Subtract the weight of the measuring base from the combined weight of the measuring base and the concrete it contains. Next, divide this weight (in pounds) by the volume of the measuring base (cubic feet) to obtain the density expressed as lb/ft 3:
