Abstract

The invention provides pervious concrete with the characteristics of high strength, long service life and durability. According to the technical scheme adopted in the invention, the pervious concrete comprises components of raw materials in parts by weight as follows: 400-500 parts of cement, 1600-1650 parts of broken stone, 10-20 parts of a reinforcing agent, 0-10 parts of a water reducing agent and 100-130 parts of water. The cement is an ordinary portland cement with the strength grade being not lower than 42.5 grade, and the reinforcing agent adopts a silicone acrylic emulsion.

Description

technical field [0001] The invention relates to a permeable concrete and a construction method, belonging to the technical field of concrete preparation. Background technique [0002] With the development of the economy and the acceleration of the pace of urban construction, the negative impact of impermeable roadbed and pavement on the urban ecological environment has also increased. As a new type of road paving material, permeable concrete has been paid more and more attention by people. In recent years, a large number of researchers have conducted research on permeable concrete pavement materials, but so far there has been no large-scale application. If the strength and durability of pervious concrete can be improved by improving and optimizing the construction process, then this new type of environmentally friendly material will be further popularized and applied. Contents of the invention [0003] One of the objectives of the present invention is to provide a permea...
