Limestone is very reactive to acid solutions, making acid rain a significant problem. Many limestone statues and building surfaces have suffered severe damage due to acid rain. Other uses include the manufacture of quicklime (calcium oxide) and slaked lime (calcium hydroxide) cement & mortar, pulverized limestone is used as a soil conditioner to neutralize acid soil conditions, crushed for use as aggregate, the solid base for many roads. Geological formations of limestone are among the best petroleum reservoirs.
