A combination aggregate commonly used within the production of concrete, ballast sand is one of the key building materials in the modern world, used for everything from pathways to skyscrapers. In this quick guide from Building Materials Nationwide, we’ll explain what ballast sand consists of, the cost and size of ballast sand bulk bags, and the two key uses for ballast sand within construction.
What is Ballast Sand?
Ballast sand is a term used for a blend of sand, small stones, and gravel. It is a type of aggregate that will be used within construction for two main purposes. The type of sand used is normally sharp sand, which is a gritty type of sand that is popularly used for concrete mixes and loosening clay soil. The gravel or stones will typically be between 10mm and 20mm in diameter and can be chunks of rocks like limestone or sourced from recycled components. Ballast is a durable building material that comes at an affordable price.
Ballast sand will typically be sold in eitherregular trade packsof 25kg in weight or largerbulk bagsof 850kg. When looking to use ballast sand within a construction project, it will normally be in your best interests to opt for bulk bags. Based on prices at the time of writing, a regular bag will cost £2.22 and a larger bulk bag will cost £48.33. To make up the 850kg volume of a bulk bag, you would need to spend £75.48 on smaller bags, an extra cost of £27.15.
What is Ballast Sand Used For?
Ballast sand, due to its loose and unappealing appearance will not be used as a decorative aggregate. Instead, it will be used for construction purposes, either within a mix or as a hidden base for other features:
Concrete: Concrete is the most popular construction material in the world, made from a combination of cement, fine aggregates, gravel, and water. By combining sand and stone, ballast saves time and effort for concrete mixes. Concrete is used for everything from the foundations of a house, to paving slabs, to skyscrapers. Ballast sand can help contribute to strong and dependable concrete while remaining cost-effective.
Sub-Bases: Sub-bases are installed as a foundation layer beneath a variety of things such as road surfaces and pathways. While for more heavy-duty applications larger aggregates like MOT type 1 would be used, ballast sand will work great as a sub-base for a path or paving.
How is Ballast Sand Mixed Into Concrete?
When looking to mix concrete from base components, cement and ballast, the ratio will depend on your needed use, with larger amounts of ballast contributing to greater strength. Opting for 1-part cement and 5-part ballast will create a mix suitable for slabs and concrete panels. For the strongest concrete, such as that used within foundations, a 1-part cement to 8-part ballast mix will be used. In order to make the strongest concrete, it will need to be reinforced, with steel rebars or mesh.

concrete mixes
Ready-mix concrete (RMC) is concrete that is manufactured in a batch plant, according to each specific job requirement, then delivered to the job site "ready to use".

. Concrete is used for everything from the foundations of a house, to paving slabs, to skyscrapers. Ballast sand can help contribute to strong and dependable concrete while remaining cost-effective.
Ballast is a mix of sand and gravel and is generally used when building foundations for specific jobs such as houses and roadways as well as railways. The reason for this is that it's heavy enough to provide a stable base and stop the structure from moving, but not so heavy that it limits drainage.
Ballast, when added to cement, binds the aggregate particles together making it strong and sturdy for making the foundations or base layers for garden walls or sheds as well as for creating path edgings and kerb ledges. Ballast can also be used to safely secure fencing posts in place.
Ballast is added to produce concrete while building sand, which contains no stones, is added to cement to produce mortar. Concrete is a rough lumpy product whilst mortar is a smooth product.
Ballast for concrete comprises of coarse materials like sharp sand, gravel, and limestone. Concrete ballast or aggregates make up the bulk of the cement mix. Recycled materials such as air-cooled furnace slag or quenched molten slag are also used in ballast.
The main purpose of ballast is to increase safety and manageability of ships in heavy seas. Disadvantages include corrosion of the ballast void and increased dispersion of invasive species.
Can I use ballast as a sub-base? Ballast is available in different types for different needs. 0-20mm ballast is perfect for sub-base and concrete foundations. 20mm screened ballast is versatile and can be used on driveways, footpaths, oversite fill as well as sub-bases.
It transfers the load from sleepers to subgrade and distributes the load uniformly on subgrade. It holds the sleepers in a firm position while the trains pass by. It prevents the longitudinal and lateral movement of sleepers. It offers good drainage to the track.
While for more heavy-duty applications larger aggregates like MOT type 1 would be used, ballast sand will work great as a sub-base for a path or paving.
Mixing 1 part cement to 6 parts ballast creates concrete suitable for driveways, paths and patios, and increasing the ratio to 1:8 gives foundation-strength concrete. It is of course possible to add other materials to increase the strength of the concrete – these often include steel reinforcing bars (“rebar”).
There are three main ballast start types: Instant Start Ballasts (IS), Rapid Start Ballasts (RS) and Programmed Start Ballasts (PS). Understanding these three features is critical when designing an application or device that utilizes UV-C lamps.
Broken stone is the best material for the ballast. Igneous rocks such as granite, quartz, etc. are used for broken stones. The size of broken stones varies from 1.9 cm to 5.08 cm.
When seeking a solid sub-base for a construction project, consider using Ballast sand. It is a commonly used granular sub-base material for gardens, driveways, and construction projects.
One of the primary ingredients is ballast, such as that available through ballast suppliers Springbridge. Ballast is added to the cement to bind the other aggregates together. The amount and type of ballast used will affect the strength of the concrete, with heavier ballast creating a stronger concrete.

What is ballast aggregate? The general rule of thumb when making concrete is to use 4 parts aggregate, 2 parts sharp sand and 1 part cement and water. The bit that is aggregate and sharp sand is collectively known as 'ballast' and is typically sold in ready-mixed bags.
