Limestone: Limestone is associated with rocks composed of either calcium carbonate, the double carbonate of calcium and magnesium, or mixture of these two constituents.
The reason for adding limestone to a container media, besides pH control, is to supply calcium and, depending on the limestone, magnesium. In this article, we will ...
What is cement? Cement is made by heating limestone (calcium carbonate) with small quantities of other materials (such as clay) to 1450°C in a kiln.
