4 Common Limestone Problems and How to Avoid Them · Limestone is a rock which is more prone to especially chemical weathering than other types of rocks such as granite. This is because calcium carbonate, which is one of the minerals found in limestone, readily reacts with rainwater. Rainwater can get acidic because of the carbonic acid that it contains. When it is exposed to carbonic acid frequently, you can see the marks of weathering on it ...
Instant stone (just add water!) · Limestone can be used for many purposes, including fertilizer and whitewash, but its most important industrial use is in making cement. When it is heated to about 1,000 °C (, in a kiln), it produces a powder called quicklime. Chemically, what's going on is that burning calcium carbonate removes carbon dioxide and leaves calcium oxide (CaCO 3 + heat → CaO + CO 2). Quicklime is a ...
