Crusher dust is made from recycled crushed rock or concrete, which is 5 millimetres or smaller in size. It contains fine particles such as soft sand, making it a valuable packing material. It is a by-product of concrete recycling; it has strong compaction abilities to create a smoother finish between pavers. Crusher dust can also be used on ...

Crushed stone is commonly used as aggregate for ready-mix concrete. Concrete plants keep large quantities of different parts of crushed stone on hand to make their concrete batches. Crushed stone with stone dust in it is highly compactable and is therefore commonly used when making any kind of base for construction, such as a …

Typically road base comprises a mixture of blue or grey rock fragments around 20 mm in size with smaller rock particles and dust (fines). Crusher dust is produced when recycled concrete or rocks are crushed. It is finer than road base comprising particles that are 5 mm or smaller in size mixed with fine particles, such as soft sand.

When making your own concrete it's important to use the correct concrete mixing ratios to produce a strong, durable concrete mixture. Some basic mixing ratios for concrete are 1:2:3, 1:3:3, 1:2:4. These mixing ratios are based on the proportions of cement : sand : stone in that order. The ratio you use will depend on what psi strength you need.
