Walking on the road, walking in the community, what is it? Let us trample on the earth steadily. In addition to the gravity of the earth, the paving slabs are quietly giving great dedication. To understand it, start with its raw materials.
1. The important raw materials of paving slabs are silty or sandy clay. The important chemical components are silica, alumina, and ferric oxide, and crystal water. Because of different geological conditions, a small amount of Alkali and alkaline earth metal compounds.
2. In addition to clay, you can also use shale, coal gangue, fly ash, etc. as raw materials to make paving tiles, because their chemical composition is similar to clay. However, because their plasticity is not as good as clay, it is often necessary to add a certain amount of clay when making bricks in order to meet the plasticity requirements during billet making.
It can be seen from the implication that the excellent characteristics of its raw materials, as well as the paving slabs. This shows the importance of its raw materials. Its low price and high quality are suitable for paving.
