是指具有较高抗压强度的混凝土铺地砖，可以接受较大的载荷，一同还能使水通过混凝土砖外表渗透到下面乃至地下。 High-strength concrete permeable bricks are concrete floor tiles with higher compressive strength, which can accept larger loads, and can also allow water to penetrate below and even underground through the appearance of concrete bricks. It is based on cement and special graded aggregate as main raw materials, mixed with appropriate amount of chemical admixtures, and mixed, stirred, shaken and pressurized or other molding processes.
The requirements for making high-strength concrete permeable bricks are as follows:
1. In order to make a permeable brick that meets the requirements of water permeability and high strength, the choice of water-cement ratio is only effective within a certain range. Its size must be consistent with the ability to completely wet the cement and make it better to wrap the aggregate. To ensure that the cement slurry does not flow, pores can be preserved.
2. The cinerary ash ratio is indeed set to have an appropriately important position in the supply intensity. The size of the ashes ratio determines whether the permeable brick can achieve an appropriately large compressive strength, and the compressive strength is determined by whether the cement slurry can form a bonding layer with a moderate thickness between the bone particles, but its influence on the permeability coefficient is mutually Opposite, smaller ashes ratio greatly increases the amount of cement per unit volume. The attacking slurry will form a dense and closed whole and then be impermeable or very small, so the appropriate ash ratio is particularly important in cooperative ratio planning.
3. Aggregate particle size is a sufficient condition for the supply of larger porosity. As long as the aggregate meets the requirements for larger porosity, talent can ensure that the product with a large amount of cement can still make the product have Higher connectivity.
It can be concluded that the reasonable deployment of the three permeable bricks that meet various functional requirements is the key to success.
