Embodiment
[0014] A method for preparing permeable bricks by using converter hot-steamed steel slag, including the surface layer of permeable bricks and the bottom layer of permeable bricks. The raw material for the surface layer: 422g of ordinary Portland cement (label 42.5), 1472g of steel slag particles with a particle size of 2-5mm, polycarboxylate Acid high-efficiency superplasticizer 6g, water 110-125g, water is added within this range according to the actual situation, the surface of the steel slag particles has a bright surface, but no flooding shall prevail; base material: ordinary Portland cement (label 42.5) Use 365g, 30g of steel slag powder, 30g of slag powder, 87g of steel slag particles with a particle size of 2-5mm, 1407g of steel slag particles with a particle size of 4-8mm, 6g of polycarboxylate superplasticizer, and 95-105g of water. Add it according to the actual situation, and the surface of the steel slag particles has a bright surface, but no bleeding shall prevail....

The invention relates to a method for preparing water-permeable bricks by using heat-stewed steel slag from converters. The method comprises the following steps of: firstly grinding and sieving heat-stewed steel slag from converters to produce converter heat-stewed steel slag particle aggregates which are used as water-permeable brick aggregates, and milling heat-stewed steel slag from converters to produce converter heat-stewed steel slag powders which are used as water-permeable brick cements; then making water-permeable brick aggregates using the converter heat-stewed steel slag particle aggregates in an addition amount of 30 to 100%, and making water-permeable brick cements by mixing the converter heat-stewed steel slag powders (addition amount of 5 to 40%) with Portland cement, slag powders, high-efficiency water-reducing agents and water; then laying layer by layer, making blanks by the vibratory pressure forming process and demoulding instantly; and finally performing wet-curing to obtain water-permeable brick products. The method makes full use of characteristics of the heat-stewed steel slag from converters. The water-permeable brick products with high strength and wear resistance are sold well in the current market, have the characteristics of low cost and environmental friendliness, and can be widely applied to pedestrian pavements, parks, squares and other places.
Description
technical field [0001] The invention belongs to the technical field of building materials, and relates to a method for preparing permeable bricks by utilizing hot-steamed steel slag in a converter. Background technique [0002] At present, the permeable bricks on the market can be roughly divided into three basic types: ceramic permeable bricks, cement-based permeable bricks and resin-bonded permeable bricks. Although ceramic permeable bricks have the advantages of high hardness, high strength, rich colors and standardized sizes, the production process is complex, resource consumption is large, and production costs are high; resin-bonded permeable bricks have poor durability due to resin aging; cement-based permeable bricks Bricks are cheap to produce, but have low compressive strength and poor wear resistance. Contents of the invention [0003] In order to overcome the above-mentioned technical shortcomings, the present invention provides a method for preparing permeable...
