Abstract

The invention relates to artificial water-permeable cobblestone and a preparation method thereof. The artificial water-permeable cobblestone comprises an outer layer and an inner layer, wherein the outer layer is prepared from the following raw materials by weight: 100 parts of outer layer aggregate, 25-45 parts of cement, 2.5-4 parts of redispersible latex powder, 0.2-3 part of a cement alkali inhibitor, 0.1-0.6 part of a water reducing agent, and 2-10 parts of a 1 wt% polyvinyl alcohol solution, the inner layer is prepared from the following raw materials by weight: 100 parts of inner layeraggregate, 20-45 parts of sand, 25-50 parts of cement, 0.1-0.8 part of redispersible latex powder, 0.5-3.5 parts of a cement alkali inhibitor, 0.1-0.8 part of a water reducing agent, and 6-28 parts ofwater, the particle size of the inner layer particles is 1-5 cm, and the outer layer has a coating thickness of 5-10 mm. According to the present invention, the outer layer aggregate is the sphericalparticles, such that the prepared water-permeable cobblestone has good water permeability, the water permeability coefficient is more than 2*10<-2> cm / s, the water accumulation problem on the cobblestone pavement is effectively improved, and the artificial water-permeable cobblestone of the present invention has anti-slip function compared with natural cobblestone pavement.

Description

technical field [0001] The invention relates to a pebble, in particular to an artificial permeable pebble and a preparation method thereof. Background technique [0002] In recent years, in order to get close to nature, there are more and more cobblestone pavements in cities, especially in park paths, garden pavements, square pavements, tourist mountain pavements, and community fitness ground pavements, etc. It is very common to use various cobblestone pavements. Because the cobblestone pavement can not only be configured with different patterns according to the needs, but also has a beautiful appearance and is closer to nature, and people walking on it has the effect of fitness. However, at present, water-blocking materials such as concrete and resin are used to pave cobblestone pavement, and the cobblestone itself is smooth and impermeable, which makes the cobblestone pavement easy to accumulate water in rainy days, and at the same time has poor slip resistance, and pedest...
