High-strength pervious concrete material and preparation method thereof

Abstract

The invention discloses a high-strength pervious concrete material and a preparation method thereof. The high-strength pervious concrete material is composed of the following components in parts by weight: 1400-1500 parts of coarse aggregate, 400-500 parts of cement, 3.2-4 parts of a dispersing agent, 3.2-4 parts of toughening fibers and 110-120 parts of water. The coarse aggregate is limestone and has a particle size of 5-10mm; the cement is G-level high-sulfate-resistance oil well cement; the dispersing agent is sulfonated sodium tannin; and the toughening fibers are plasma treatment cellulosic fibers. The preparation method comprises the following steps: adding cement and water into a stirrer, stirring to be in a slurry state, sequentially adding the coarse aggregate, the dispersing agent and the toughening fibers, stirring to be uniformly mixed, pouring the mixture in a strength test mold, vibrating and compacting, and curing in a water bath curing box. According to the high-strength pervious concrete material disclosed by the invention, the compressive strength and corrosion resistance of the current pervious concrete are improved, good water permeability and durability of thepervious concrete are ensured, the production cycle is short, and the high-strength pervious concrete material has wide market prospects.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a permeable concrete material and a preparation method thereof. Background technique [0002] With the continuous acceleration of urbanization, a series of environmental problems caused by it are becoming more and more prominent, such as urban ground subsidence, heat island effect, serious water accumulation, noise pollution and other issues, which have seriously affected people's production Life. [0003] Due to its serious compactness, traditional lightweight high-strength concrete cannot dissipate heat, breathe, and permeate water, and has a high weight, which to a certain extent exacerbates urban heat island effects, noise pollution, and other problems. It cannot be eliminated, thereby causing road surface pollution, and cannot alleviate the problem of flooding of low-lying areas by rainfall. [0004] At present, domestic research on pervious concrete is in the s...

Problems solved by technology

[0006] Although the above technologies have prepared pervious concrete with certain properties to a certain extent, they are less involved in high-strength pervious concrete. The current compressive strength can only be maintained within 30MPa. Research on high-strength pervious concrete still in its infancy
