Mineralogical Composition of Limestone Rock and Soil

INTRODUCTION. Weathering significantly alters the chemical, mineralogical and physical properties of the rocks and results in different properties. However, the effect of weathering on the geological and geomechanical properties of limestone rock is not well known (Tugrul and Zarif, 2000).Limestone composition is dominantly that CaO in CaCO 3 (CO 2 content usually not

tion of limestone content depends on knowledge of the purity of limestone. While a limestone that contains 100 % calcium carbonate loses 44 % of its mass due to CO 2 loss, a limestone that is only 70 % CaCO 3 would lose only 31 % of its mass from CO 2 loss. Without knowledge of limestone purity, the determination of limestone content is subject ...
