Cement prefabricated square bricks
The advantage of fast masonry speed meets the requirements of wall reform in the development of building industrialization. Bricks are traditional masonry materials. It has gradually shifted from using clay as the main raw material to utilizing industrial waste such as coal gangue and fly ash, and from solid to porous and hollow, and from sintered to non sintered. It can be divided into three categories based on size: large, medium, and small. At present, China mainly produces small and medium-sized building blocks. Blocks with a height between 380-940mm are considered medium-sized; Blocks with a height less than 380mm are considered small. According to materials, it is divided into blocks such as concrete, cement mortar, aerated concrete, fly ash silicate, coal gangue, artificial ceramic particles, slag waste, etc. According to the structure, building blocks are divided into two types: dense and hollow. Hollow blocks include circular holes, square holes, elliptical holes, single row holes, multi row holes, etc. Dense or hollow blocks can be used as load-bearing walls and partitions. Bricks: Divided by material: clay bricks, shale bricks, coal gangue bricks, fly ash bricks, gray sand bricks, concrete bricks, etc.
