How to Tell the Quality of Paver Stones?

Due to the good permeability of permeable bricks, they are widely used in urban road renovations and have become a popular industry for many investors to invest in. How to differentiate the quality of such bricks as permeable bricks? It can be done in three steps:

To understand the production equipment for water bricks, the pressure of the equipment directly affects the quality of the tiles. Tiles produced by equipment with different pressures have varying densities. The higher the pressure of the equipment, the denser the colored tiles will be, with better flexural strength and higher compressive strength. Conversely, these properties will be lower. To produce tiles 80mm thick that meet the requirements of the People's Republic of China's CJJ79-98 specification for the construction and acceptance of interlocking pavement bricks, the press pressure should be around 100 tons.

2. Understanding the production process of water bricks is crucial, as the quality varies significantly between different processes. Concrete cast bricks are vastly inferior in quality compared to those formed through high-frequency vibration. Bricks formed by high-frequency vibration are not only denser, with higher compressive strength and bend resistance, but also have a finer surface texture. Additionally, the higher the vibration frequency of the mold, the greater the density of the bricks produced, along with a superior surface texture and higher compressive strength.

3. It's crucial to inspect the cement mortar mix ratio used in the permeable bricks. The pigments used must meet the standards; high-quality pigments possess high antioxidant strength and are less prone to fading. Particularly, inorganic pigments have higher antioxidant strength compared to organic ones.
