Growth of dolomite crystals American Journal of Science
The surfaces of the crystals have a Ca to Mg ratio in excess of 4; the surface layer is about 100A thick and approaches the composition of dolomite at its inner side. Successive fractions have been dated by C14 and thus place a time parameter on the introduction of magnesium into the .

Properties of Concrete Incorporating Dolomite Powder
Dolomite is a rock forming mineral which is noted for remarkable wet ability and dispensability as well as moderate oil and plasticizers absorption. Dolomite has good weathering resistance. Two kinds of dolomite fine powder with mean particle size 4μm and μm and specific surface 5500 cm2/g and 7523 cm2/g, respectively, were examined.

Introduction to Refractories – IspatGuru
Sep 28, 2013· Introduction to Refractories. ... Dolomite refractories – These are basic refractories made from dead burnt dolomite. Dolomite (CaCO3+MgO3) when dead burnt by high temperature firing produce CaO+MgO. For dolomite refractories CaO+MgO greater than 97 % is desirable. This percentage of CaO+MgO is usually obtained from high purity dolomite.
