Abstract

The invention discloses permeable concrete. The permeable concrete is prepared from, by weight, 250-300 parts of cement, 10-15 parts of coal ash, 6.32-9.68 parts of volcanic ash, 18-25 parts of carbide slag, 15-24 parts of quartz sand, 2.2-5.3 parts of triethanolamine, 1.3-2.7 parts of sodium sulfate, 2.5-3.6 parts of a water reducing agent, 0.8-1.7 parts of a retarder, 3.2-4.8 parts of a foaming agent and 30-35 parts of water. The permeable concrete is good in construction workability, large in porosity, good in water permeability, good in abrasive resistance, high in compressive strength and bending strength and good in anti-frost property.

Description

technical field [0001] The invention relates to the field of road paving materials, in particular to a 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 modern cities is gradually covered by reinforced concrete buildings and impermeable roads. Compared with natural soil, concrete pavement lacks the ability to breathe, absorb heat and infiltrate rainwater, which brings a series of environmental problems. [0003] In urban construction, occasions that require high water permeability, such as roads in parks, sidewalks, squares, stadiums, botanical gardens, lightweight roads, parking lots, underground construction projects, and various new sports venues, etc., can be considered to use water permeability water concrete. [0004] Permeable concrete, also known as porous concrete, sand-free concrete, and permeable floor, is a porous lightweight concrete ma...
