What are the wall masonry materials?

Masonry materials mainly include: traditional stones, bricks, tiles and blocks. Modern hollow blocks and plates. Masonry mortar.

Classification of bricks: according to materials, they are divided into clay bricks, lime-sand bricks, shale bricks, coal gangue bricks, cement bricks and various industrial waste bricks (such as fly ash bricks and slag bricks). ); According to the production shape, it is divided into solid brick, porous brick and hollow brick.

Ordinary clay brick has high strength, good frost resistance, convenient manufacture and wide application. However, because the raw materials for brick making are from clay, the cultivated land has been destroyed. In recent years, other materials have been used to replace clay bricks to make lime-sand bricks, fly ash bricks, slag bricks, coal gangue bricks and shale bricks.

Mortar is made of cement, fine aggregate and water. There are cement mortar, lime mortar and mixed mortar. Mortar strength is also expressed by numbers, which can be divided into five types: 100, 50, 25, 10 and 4, and commonly used ones are 25 and 50.

Extended data

The traditional masonry materials in China are mainly sintered ordinary bricks (solid clay bricks) and stone. Sintered common brick once occupied an "absolute dominant" position in the composition of wall building materials in China, and it is the "kingdom" of sintered common brick in the world.

Because the sintered common brick does not meet the requirements of sustainable development from any angle of destroying land, consuming resources and energy and polluting the environment, in recent years, China has vigorously developed various masonry materials, such as soil saving, energy saving, slagging, waste changing, multi-function and environmental protection.
