3 Aggregate Properties

is a carbonate rock which consists largely of calcium magnesium carbonate. The word dolomite is the mineral calcium magnesium carbonate Ca Mg (Co 3)2. INDOT uses an elemental magnesium (Mg) content test to determine if a rock source is dolomitic. An elemental magne sium content of percent or above is required for dolomite aggregates.
