Problems solved by technology

However, the current permeable concrete has a contradiction between strength and water permeability, and its work performance is poor, which limits the use of permeable concrete. Therefore, in view of this shortcoming, it is of great significance to develop high-strength and high-permeability concrete.

Abstract

The invention discloses a high-strength water-permeable concrete and a preparation method thereof, belonging to the technical field of concrete. The key points of the technical scheme are calculated in parts by weight. The high-strength water-permeable concrete includes the following components: cement, reinforced aggregate, water-permeable aggregate, Reinforced fiber, toughening agent, water reducer, water; the reinforced aggregate includes gravel and high-strength ceramsite; the water-permeable aggregate includes zeolite and shell particles; the reinforced fiber includes carbon fiber and bamboo fiber. In the present invention, reinforced aggregate and reinforced fiber can improve the strength of concrete, toughening agent can improve the toughness, strength and water permeability of concrete, and bamboo fiber, zeolite and shell particles play a synergistic effect, so that water is quickly diverted and absorbed, thereby It is quickly discharged from the surface of the concrete; and the bamboo fiber and shell particles have antibacterial properties, which can reduce the growth of bacteria in hot and humid environments and improve the durability of concrete.

Description

technical field [0001] The invention relates to the technical field of concrete, more specifically, it relates to a high-strength water-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 road surface hinders the infiltration of rainwater, so that the replenishment of groundwater by rainwater is blocked, 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 surface when the tires roll in. After the ti...
