Paver bricks are artificial blocks made from concrete and industrial waste materials such as slag and fly ash, or local materials. They are larger in size than bricks, featuring simple equipment and fast construction speed, and meet the requirements for wall reform in the development of building industrialization.

Paver bricks are categorized into small, medium, and large sizes based on their dimensions and quality. In the paver series, bricks with a height greater than 115mm and less than 380mm are classified as small bricks, those with a height of 380~980mm as medium bricks, and those taller than 980mm as large bricks. Small and medium-sized bricks are predominantly used.
