Action of acids, oils and fats upon concrete

With regard to the mineral acids-e.g., hydrochloric, nitric, and sulphuric acids-there is little to be said. Neither cement nor concrete will withstand the action of these acids, which decompose and dissolve the constituents of cement, even in dilute solution. Even a weak acid, like carbonic acid, has a distinct action upon cement, which, suspended in water, can be practically entirely carbonated- by passing a current of carbon dioxide into it.
