porous an aggregate is determines how much liquid can be absorbed when soaked in water. The test method AASHTO T 85 defines absorption as the increase in the weight of aggregate because of water in the pores of the material, but not including water adhering to the outside surface of the particles.


Screening. What is Screening? Screening is the separation of material into 2 - 6 different sized products. The material is separated by passing it through a vibrating 'screen box' which has a number of different sized screens, or meshes, which the material falls through like a seive.

• The material is crushed with cone crushers, jaw crushers, hammer mills, or pug mills and is screened for size. Oversized material is returned to the crushers, and the material that passes through the screens is transferred to the storage. • From the storage, the material is fed to a rotary kiln, which is fired with coal, coke, natural


instance, two billion tons of aggregate are produced each year in the United States, is expected to raise to more than 2.5 billion tons per year by the year 2020 (FHWA, 2004). Crushing of concrete to produce coarse aggregate for the production of new concrete is one common means for achieving a more environmentally-friendly concrete.

Crusher - Wikipedia

A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, or rock dust.. Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different composition can be differentiated.
