Aglime Terms |

DOLOMITE - Limestone that contains magnesium carbonate (MgCO3) in an amount approximately equivalent to the calcium carbonate content in the stone. Limestone containing magnesium carbonate in lesser proportions is referred to as magnesium limestone or Dolomitic limestone.


Fineness modulus is generally used to get an idea of how coarse or fine the aggregate is. More fineness modulus value indicates that the aggregate is coarser and small value of fineness modulus indicates that the aggregate is finer.
