Crusher Run (Crush and Run) Crusher run is a blended mix of coarse aggregate and fine aggregate. The combination of both crushed stone and stone dust creates a low void content (the amount of space or air between the pieces of rock in a mix) that is valuable in concrete construction for its compaction ability and drainage characteristics.

Concrete, cement and other wastes in construction waste can be used as building aggregates and recycled brick raw materials after being reasonably crushed, screened and crushed. And the main equipment used for crushing concrete can be divided into two types: traditional fixed crusher and mobile concrete crusher, among which small crushing equipment is favored by users.

Hi, Would like to know if there any problems using crusher dust for my concrete instead of sand and gravel, the crusher dust has a fair bit of powder so it mixes ok but i''m want to use it for footings for raised floor of ganny flat, was going to use mix of 4:1 have used it for chooks pens etc and seems alright but don''t know how strong it is to use for house footings. thanks Rick

Coarse aggregate production typically yields 25% to 45% crusher dust depending on the parent rock, crushing equipment and crushing conditions . The UK has significant reserves of crusher dust in its quarries, which could undergo further processing to provide the majority of the sand required by the construction industry, using the same sales and delivery channels as it does now for its coarse

Parts of crushed stone are commonly used as aggregates 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.
