Approximate Cost. While this depends on what you build with this concrete alternative, 13 tons of gravel costs about $1,300 to $1,600 which is roughly the amount needed for an average driveway. However, if you have a smaller area, you may not need as much gravel, reducing the cost to $300 to $1,000.

Bulk Density of Aggregate. The Unit weight or bulk density of aggregate is the mass or weight of the aggregate required to fill a container of a specified unit volume. The approximate unit weight of aggregate that is commonly used in normal concrete work is between 1200-1750 kg/m 3 (75-110 lb/ft 3) Bulk Density of Sand
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.
What is a Concrete Aggregate? 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.
Sieve sizes commonly used for concrete aggregates are detailed in Table 1, and various physical properties of normalweight aggregates, with typical range values, are shown in Table 2. Coarse and fine aggregates are generally sieved separately. That portion of an aggregate passing the 4.75 mm (No. 4)
