Abstract

The invention discloses a preparation method of concrete water-permeable bricks with good water-permeable effect. The preparation method includes following steps: well mixing construction waste coarseaggregate, rapid-hardening sulfate aluminum cement, polyethylene composite, diatomite, construction waste micropowder, slag, asphalt particle and borax, forming under pressure, naturally drying, using hot air to dry to constant weight, and cooling to obtain a pre-pressed material; heating and sintering the pre-pressed material, and heating and sintering again to obtain the concrete water-permeable bricks. A preparation process of the polyethylene composite includes: sending sucrose fatty acid ester, lecithin and water into an emulsifying tank, continuously feeding nitrogen to the bottom of the emulsifying tank, stirring, adding polyethylene, homogenizing, irradiating, adding polyamide, and heating while stirring to obtain the polyethylene composite. Water-permeable gaps inside the concrete water-permeable bricks are uniform, the concrete water-permeable bricks are good in water-permeable effect and excellent in mechanical performance and durability, meet requirements on compressive strength of concrete pavement bricks and have a noise absorbing function.

Description

technical field [0001] The invention relates to the technical field of permeable bricks, in particular to a method for preparing a concrete permeable brick with good water permeable effect. Background technique [0002] Floor tiles are subject to greater pressure and therefore require higher strength. The existing floor tiles have high density, such as concrete floor tiles. These floor tiles are all formed from the same material at one time, and the internal material has fewer pores. Moreover, the pores are not connected and impermeable, which cuts off the communication between the roadbed and the outside world. , destroying the natural ecological environment. Although the existing water-permeable floor tiles have a certain water-permeable function and meet the ecological needs, their mechanical properties are poor, especially the water-permeable effect of the cement paste can not meet the needs, and urgently need to be solved. Contents of the invention [0003] Based on...
