What is "limestone"?
Limestone is a type of rock made mainly of calcium carbonate, often formed from the remains of marine organisms. It is typically light in color, ranging from white to gray or yellow, and is known for its durability and versatility in construction. Limestone is commonly used for building materials, such as bricks, tiles, and decorative stones, as well as in road construction and as a filler in concrete. Additionally, it can be used in various industrial processes, including the production of lime for chemical applications. Its natural beauty and workability make limestone a popular choice for both structural and aesthetic purposes in architecture and landscaping.
