Abstract

The invention belongs to the technical field of building materials and particularly relates to an early strength cementing material for water-permeable concrete, comprising, by weight according to theformula of materials, 30-55% of ordinary Portland cement, 10-20% of high-iron calcium aluminate cement, 15-30% of micronized mineral powder, 10-20% of metal sulfates, 0.5-2.5% of a water-soluble flocculant, 1-5% of water-absorbing expandable organic material, 0.5-2.0% of melamine water reducer powder, and 2-7% of a lubricant. The high-iron calcium aluminate cement and the metal sulfates cooperateto improve 3d strength; the micronized mineral powder and the ordinary Portland cement can cooperate to improve 28d strength; the water-absorbing expandable organic material and the water-soluble flocculant can cooperate to improve wrapping property and water-holding capacity of concrete; the melamine water reducer powder and the lubricant can ensure low slump and mobility of water-permeable concrete.

Description

technical field [0001] The invention belongs to the technical field of urban pavement structures, and relates to an early-strength cementing material for permeable concrete, which is used for lightweight roads such as sidewalks, light carriageways, ground decoration, landscape roads, city squares, stadiums, fire exits, and parking lots. project. Background technique [0002] With the continuous development of urban modernization, the urban heat island effect is significant. High temperature accelerates photochemical reactions, aggravates air pollution, and damages human health. The city is covered by reinforced concrete, which has poor water and air permeability, resulting in poor breathability of the road surface and poor penetration of rainwater. Permeable concrete has a porous structure, which can improve the situation of low groundwater level, increase urban groundwater resources, improve the city's climate, and improve the environment. At present, pervious concrete ha...
