Limestone used in cement production and aggregates used in ready-mix concrete industry are also routinely taken from nature by the quarrying of natural limestone resources (Mehta, 2002; Naik, 2007). Quarrying for limestone damages the environment and adds to greenhouse gas emission due to the gasses released into the

Cement manufacturing begins with quarrying operations in which limestone in mines is quarried and brought to crusher for crushing. Limestone quarries are opencast mines. Often limestone appears as an outcrop right on the surface. At other times it is under an overburden that can vary in depth but is generally less than 3 metres thick.
