Abstract

The present invention relates to the field of building material, in particular the process for making and use of permeable steel slag colored pavement bricks, characterized in that steel slag is used as coarse and fine aggregate to replace sand and gravel, wherein the raw materials of the colored pavement bricks are added with 60%-80% of steel slag with grain size being 0-20mm apart from the No. 425 common silicate cement. In the forming process of the steel slag colored pavement bricks, the die roof board is provided with 5-15 inverted polygons or cones, thus forming a series of inverted taper holes on the opposite sides of the pavement bricks during vibration molding.

Description

technical field

[0001] The invention belongs to the field of building materials, in particular to a steel slag colored pavement brick with a water-permeable function. Background technique

[0002] The current pavement bricks are roughly divided into ceramic-based and cement-based pavement permeable bricks. However, due to the high cost of ceramic-based pavement permeable bricks, they cannot be widely promoted at present. At present, cement-based pavement permeable bricks cannot completely overcome the problem of excessive strength drop after freezing and thawing. Steel slag is a kind of metallurgical solid waste that is difficult to use with high added value at present, and there are serious stockpiling problems in major steel factories in my country. On the one hand, the stockpiling of a large amount of steel slag occupies a large amount of land, consumes a lot of management costs and causes certain environmental pollution.
