High-strength and water-permeable concrete and preparation method thereof

Abstract

The invention discloses high-strength and water-permeable concrete and a preparation method thereof and belongs to the technical field of concrete. The technical scheme is characterized in that the high-strength and water-permeable concrete is prepared from components in parts by weight as follows: cement, reinforced aggregate, water-permeable aggregate, reinforced fibers, a flexibilizer, a waterreducing agent and water, wherein the reinforced aggregate comprises crushed stone and high-strength ceramsite; the water-permeable aggregate comprises zeolite and shell particles; the reinforced fibers comprise carbon fibers and bamboo fibers. Strength of the concrete can be improved by the reinforced aggregate and the reinforced fibers; flexibility, strength and water permeability of the concrete can be improved by the flexibilizer; the bamboo fibers, the zeolite and the shell particles play a synergistic role, so that moisture is diverted and adsorbed rapidly and discharged from the surfaceof the concrete rapidly; the bamboo fibers and the shell particles have antibacterial performance, accordingly, bacteria bred in a hot and humid environment can be reduced, and durability of the concrete is improved.

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...

AI Technical Summary

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.
