What makes concrete so strong is the chemical reaction that occurs when cement and water mix — a process known as hydration. "Hydration occurs when cement and water react," says Ulm. "During hydration, the clinker dissolves into the calcium and recombines with water and silica to form calcium silica hydrates."

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. Crusher run is typically used underneath concrete slabs, patios, driveways, sidewalks, and walkways ...
Crushed Stone #10 (Stone dust or screenings): Usually 1/8″ Wide or Smaller. Crushed stone number 10 is the finest grade and is often referred to as dust or rock/gravel screenings. Resembling coarse sand, #10 is produced as a byproduct of the crushing process and has many uses in the construction and landscaping industries:
Type A – Crushed stone, higher-quality base. Type B – Crushed or uncrushed gravel, areas with gravel as a local material. Type C – Crushed gravel, +60% with 2 or more crushed faces. Type D - Allows use of Type A or crushed concrete (where economically feasible). Type E – Caliche, iron ore, or for new materials as shown on plans.
Cons Of Using Crushed Concrete. 1. It Can Be Dangerous. One of the biggest cons of using crushed concrete is that it can be dangerous.

Clean rock products contain no fines (small particles of ground rock). Minus rock does contain fines. Fines help a product compact. For example, if you're building a driveway over soft ground, a minus product can compact and stay in place. Watch the video to see the difference between crushed clean and crushed minus rock products.
