What is Fire Resistance of Concrete? Mechanism …

Limestone, dolomite and lime rock are called carbonate aggregates because they consist of calcium or magnesium carbonate or coinations of the two. During exposure to fire, these aggregates calcine - carbon dioxide is driven off and calcium (or magnesium) oxide remains. Since calcining requires heat, the reaction absorbs some of the fire''s heat.
