We have all seen the microscopic arrangements of plants and animals, but do you know the microstructure of landscape tiles ? What are the microstructures of landscape tiles and how do they function?
The landscape brick is a part of sintered material, because the fire resistance of the material is low, so the firing temperature is low. The solid phase reaction is very incomplete. In addition to the new phase generated by the solid phase reaction, a large amount of minerals from the material, such as quartz, are often left in the product. Generally, products calcined from calcareous (including dolomite) materials have crystalline phases such as calcareous, wollastonite, perovskite, hematite, and quartz; while products calcined from low calcareous materials, There are lime, cryolite, cristobalite, hematite and a few mullite.
The glass phase is also called liquid phase. The relative strength of glass in landscape brick products plays an important role. Because the firing temperature is not high, the glass phase content is only about 3%.
Landscape brick products have open and closed pores with various pore sizes, and the porosity is about 10% -30%. Porosity and pore structure determine or affect many important properties of the product.
The above is the microstructure of landscape tiles. You must understand this, so that you can better improve the quality of landscape tiles.
