satisfactory yield. high fines content invariably present in crushed rock aggregate was considered to be unsuitable for use in concrete because of the high water demand and the presence of clay size particles. another disadvantage was the particle shape. yet, crushed rock material, after removal of fines (by washing or other means) was successfully
crushed stone aggregates are produced by crushing quarried rock, then screening it to sizes appropriate for the intended use. production of crushed stone has three stages primary crushing to break down the stone to a manageable size secondary and tertiary crushing to render the rocks into sizes specific to their applications and screening to separate the crushed stone for further processing
