Abstract

The invention provides a water permeable brick material, which sequentially comprises a surface layer material and a bottom layer material from top to bottom, wherein the surface layer material comprises a facing material, a surface layer water reducer and surface layer water; the facing material is prepared from the following components in parts by weight: 10-30 parts of cement, 60-85 parts of first steel slag and 1-10 parts of fine construction waste; the addition amount of the surface layer water reducer is suitable; the addition amount of the surface layer water is suitable; the bottom layer material comprises a bottom material, a bottom layer water reducer and bottom layer water; the bottom material is prepared from the following components in parts by weight: 10-30 parts of the cement, 30-60 parts of the first steel slag, 15-40 parts of coarse construction waste and 1-10 parts of fine construction waste; the addition amount of the bottom layer water reducer is suitable; and the addition amount of the bottom layer water is suitable. The invention further provides a preparation method of the water permeable brick. The water permeable brick and the preparation method thereof provided by the invention solve the problem of insufficient supply of electric furnace steel slag and expands a new way of utilization of the construction waste.

Description

technical field [0001] The invention belongs to the technical field of new building materials, and relates to a permeable brick and a preparation method thereof, in particular to a method for preparing a permeable brick by using the sorted electric furnace steel slag aggregate and construction waste as aggregate. Background technique [0002] With the continuous development of urban modernization, the city is covered by reinforced concrete, and the impermeable pavement has poor breathability and cannot penetrate rainwater. The permeable steel slag concrete brick has the characteristics of porous structure and large porosity, which can penetrate rainwater, increase urban groundwater resources, improve urban climate, and protect the environment. Permeable concrete bricks can be widely used in road engineering and parking lots in municipalities, residential areas, gardens, squares, etc. [0003] Steel slag is the waste slag produced in the steelmaking process, and its properti...
