crushed concrete is known as recycled concrete because it comes from older blocks and slabs that are no longer in use. large blocks of concrete or asphalt go through a crusher that mills them into crushed concrete. the final product is concrete stones roughly in size, similar to gravel. It also includes stone dust to fill the space In crusher dust, the particles are generally high, a major concern limiting its percentage replacement to minimum with sand in a concrete mix. It can be replaced to the amount 25%. its availability is not a concern.
recycled concrete, or crushed waste concrete, is a feasible source of aggregates and an economic reality, especially where good aggregates are scarce. conven-tional stone crushing equipment can be used, and new equipment has been developed to reduce noise and dust. aggregates must conform to certain standards forconcrete mix design -definition concrete mix design is defined as the appropriate selection and proportioning of constituents to produce a concrete with pre-defined characteristics in the fresh and hardened states. In general, concrete mixes are designed in order to achieve a defined workability, strength and durability
