    Nov 01, 1997· Due to the shortage of river sand, sea sand and crushed sand are being used in many construction sites. Crushed sand is different in shape, grading, and content of very fine sand (VFS) compared with river sand, and it is well known that the material properties of crushed sand concrete are also different from those of river sand concrete (1-3).

  • The composition of limestone What is limestone

    Dolomite was named after the Dolomite mountains in southern Europe. It is a carbonate mineral that often forms from calcite. Sometimes liquids rich in magnesium carbonate (MgCO 3) (an atom of magnesium, an atom of carbon and three atoms of oxygen) pass through a limestone.When this happens, the CaCO 3 of the calcite picks up the MgCO 3, so forming dolomite.

  • Limestone Wikipedia

    Limestone is a carbonate sedimentary rock that is often composed of the skeletal fragments of marine organisms such as coral, foraminifera, and molluscs.Its major materials are the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO 3).A closely related rock is dolomite, which contains a high percentage of the mineral dolomite, CaMg(CO 3) 2.
