Abstract

The invention discloses water-permeable concrete, which is prepared from the following components in parts by mass: 300 to 500 parts of cement, 1,500 to 1,700 parts of aggregate, 9 to 15 parts of water reducing agent, 15 to 50 parts of enhancer and 90 to 125 pars of water, wherein the enhancer is prepared from silica fume, ultrafine powder and a nano material TiO2; in percentage by mass, in the enhancer, alumina accounts for 0.92 percent, calcia accounts for 0.14 percent, iron oxide accounts for 0.27 percent, magnesia accounts for 1.59 percent and silica accounts for 93.11 percent; the iglossis 3.18 percent. The water-permeable concrete prepared by the preparation method is high in water permeability coefficient and high in compressive strength, and meets a high-strength requirement of the construction of a road surface.

Description

technical field [0001] The invention relates to the field of concrete, in particular to a permeable concrete and a preparation method thereof. Background technique [0002] Ordinary concrete pavements used on the surface of modern cities lack the ability to breathe, absorb heat and infiltrate rainwater, which brings a series of environmental problems. Using permeable concrete to pave the road is the way to solve this series of problems. The existing permeable concrete mix ratio is designed according to the method stipulated in the "Technical Regulations for Permeable Cement Concrete Pavement" (CJJ / T135-2009), which is not suitable for road construction with higher strength requirements. [0003] Aiming at the problems in the related technologies, no effective solution has been proposed yet. Contents of the invention [0004] In view of the above-mentioned technical problems in the related art, the present invention proposes a permeable concrete and a preparation meth...
