Abstract

The invention relates to carbon fiber reinforced water permeable concrete and a preparation method thereof. The technical problems that water permeable concrete in the prior art has low compressive strength, poor durability, a poor water permeation effect and a short service life. According to the provided carbon fiber reinforced water permeable concrete and the preparation method thereof, the concrete is prepared from, by weight, 130-170 parts of cement, 20-30 parts of steel slag, 15-22 parts of magnesium oxide, 13-15 parts of calcium oxide, 16-30 parts of coal gangue, 15-30 parts of fly ash,2-6 parts of epoxy acrylate resin, 2-2.5 parts of polypropylene fiber, 10-30 parts of chopped carbon fiber, 40-60 parts of gravel, 20-30 parts of coarse sand, 0.5-0.8 part of lithium carbonate, 2-5 parts of nonionic surfactant and 170-182 parts of water; at the same time, the preparation method of the concrete is also provided. The carbon fiber reinforced water permeable concrete and the preparation method thereof are widely used in the technical field of road materials.

Description

technical field [0001] The invention relates to the technical field of road materials, in particular to a carbon fiber reinforced permeable concrete and a preparation method thereof. Background technique [0002] With the development of social economy and the process of urban construction, the surface of the modern city is gradually covered by reinforced concrete buildings and impervious roads. Compared with the natural soil, the modern surface brings a series of problems to the city. The main manifestations are as follows: (1) The impermeable pavement hinders the infiltration of rainwater, which blocks the replenishment of groundwater by rainwater. Coupled with the excessive extraction of groundwater, the urban ground is prone to subsidence. (2) On the traditional dense road surface, tire noise is loud. When the vehicle is running at high speed, the tires will press air into the gap between the tires and the road when the tires roll in. When the tires roll over, the air wi...
