What is the chemical composition of stone?

The main components of stone are calcium carbonate CaCO3, calcium hydroxide Ca(OH) and calcium oxide CaO. The most important use of stone in modern life is concrete. Making cement, even making concrete with cement, sand, pebbles or gravel, is all stone. Stone generally refers to a small rock mass that falls off when a large rock mass encounters an external force. Most of them are attached to the surface of large rock mass, generally in block or oval shape, with rough or smooth appearance and firm and brittle texture.

Stones are also classified, and the specific chemical composition is as follows:

1. For example, stones for laying railway tracks and pebbles along the river are mainly composed of a mixture of calcium carbonate, calcium silicate and silicon dioxide.

2. The chemical composition of rocks is mainly silicate.

The main component of ordinary stone is silicate, which is similar to cement.

4. A few sedimentary rocks, such as limestone, are mainly calcium carbonate, which is one of the raw materials for producing lime and cement.

The most intuitive impression of stone is its massiness, especially its rough shape, which makes it look tough at home. Modern stone furniture has simple and smooth lines, like straight white stone products, full lines, which make people feel very comfortable. Most home owners like to use jade as an ornament to show a luxury at home. Some furniture brands, in addition to a large number of stone dining tables and coffee tables, many large pieces of furniture such as wardrobes and beds are inlaid with jade, which quite continues the tradition of Chinese classical furniture inlaid with teeth, porcelain, jade and mother of pearl for decoration.
