limestone is a sedimentary rock consisting of more than 50% calcium carbonate ( calcite - caco 3 ). there are many different types of limestone formed through a variety of processes. limestone can be precipitated from water ( non-clastic, chemical or inorganic limestone), secreted by marine organisms such as algae and coral (biochemical.limestone driveway vs. gravel driveway | acadiana shell,limestone. limestone is available in a number of different sizes and styles to suit your individual needs and tastes. some homeowners prefer the traditional, subtle look of washed clean stone. it’s carefully pulverized and screened to size. the typical size used for a driveway is 3/4″, although 3/8″ or 1 1/2″ may also be used. gravel.crushed concrete vs gravel | materials and benefits,however, gravel that is crushed will have a more angular shape. sizes. the crushed stone ranges in size from fine stone dust (screenings) to larger and heavier stones. gravel comes in various sizes that are larger than 2 mm in diameter, starting from about a ¼.crushed stone vs. gravel and how gravel suppliers can help,however, gravel that is crushed will have a more angular shape. sizes. crushed stone ranges in size from fine stone dust (screenings) to larger and heavier stones. gravel comes in various sizes that are larger than 2 mm in diameter, starting from about a ¼ inch, and
