Manual Calculation
Find the volume of your project:
length * width * heightMultiple the volume of your project by the density of your aggregate.
lbs/cubic feetDivide the result by
2000 to get the tons needed.Density
Limestone
Screenings = 113 Lbs/Cubic Feet
Crushed Stone = 138 Lbs/Cubic Feet
Coarse Aggregate = 96 Lbs/Cubic Feet
Sand = 106 Lbs/Cubic Feet
Granite
Screenings = 113 Lbs/Cubic Feet
Crushed Stone = 145Lbs/Cubic Feet
Coarse Aggregate = 96 Lbs/Cubic Feet
Sand = 106 Lbs/Cubic Feet
Sand & Gravel
Screenings = 113 Lbs/Cubic Feet
Crushed Stone = 130 Lbs/Cubic Feet
Coarse Aggregate = 98 Lbs/Cubic Feet
Sand = 110 Lbs/Cubic Feet
Types of Aggregate
Limestone Aggregates
Limestone aggregates are creating through the crushing of sedimentary rock. This type of aggregate is one of the most commonly used in road construction and reinforced concrete aside from granite and gravel. Limestone aggregate is used as a rock filler under concrete slabs that form the foundation for homes, businesses, utilities, bridges, and almost every other type of infrastructure.
Granite Aggregates
This is the best aggregate for high-grade concrete, and as it comes in a variety of shades, like grey, red and pink, it can also be used as a decorative feature. Granite itself is composed of feldspar, quartz and mica crystals, which dictate the color of the stone.
Gravel/Ballast Aggregates
Gravel aggregates are sourced by sifting quarried rock and crushing natural stone. Gravel aggregates don’t possess as much strength as their granite counterparts, but they are often cheaper to purchase.
Sand
Sand is used to provide bulk and strength for materials like asphalt and concrete, as well as being used for decorative purposes. Sand combines with water and other aggregates to form the solid, durable concrete that is used in countless applications all over the world. It also plays a key role in the binding agent in asphalt, transporting it throughout the mix.
Uses of Aggregate
Aggregates are used in construction for a number of different reasons. In roads and railway ballast they are used to resist the overall (static as well as dynamic) load, distribute the load properly and to drain the water off the surface. They are also used in water filtration and sewage treatment processes.
- As a Load Bearing Material.
- As a Filling Material.
- As an Infiltrating Material.
Uses of Aggregate in Concrete
Aggregate is an essential ingredient of concrete. The uses of aggregates in concrete is:
- Increases the volume of concrete, thus reduces the cost. Aggregates account for 60-75% of the volume of concrete.
- To provide a rigid structure.
- To reduce the shrinkage and cracking.
- Concrete aggregate is used in many structures and substructures e.g. different elements of a Building, bridges, foundations.
- The smaller the aggregate size the greater its surface area and the more binding material will be required.
