Embodiment 1

[0028] Embodiment 1. A pavement brick produced by industrial waste slag is characterized in that it contains the following components by weight percentage: 37% of granulated blast furnace slag (particle size not greater than 6mm), high fine slag powder (specific surface area not less than 420cm² / g) 7%, aeolian sand 20%, washed sand 16%, and the balance is cement.

[0029] The production method comprises the following steps:

[0030] Step 1. Prepare raw materials: Granular raw materials are transported into the factory by car, and after passing the sampling test, they are stored in five raw material storage sheds with a storage capacity of about 2000 tons each; powder raw materials are directly pumped into a steel silo with a storage capacity of 100 tons for storage.

[0031] Step 2. Screening and mixing: install electric vibrating screens on various raw material batching bins, screen out agglomerated or large particle materials during the loading process of the forklift, and ...

Abstract

The invention discloses a pavement brick produced from industrial waste residues and a production method thereof, belongs to the field of building materials, and solves the problems that natural resources used as the building materials are increasingly exhausted and the resource utilization rate of the industrial waste residues is insufficient. The pavement brick comprises the following components: granulated blast furnace slag or converter steel slag, superfine slag powder or fly ash, aeolian sand, washed-out sand and cement. The production method comprises the following steps: adding granulated blast furnace slag or converter steel slag, aeolian sand, washed-out sand and water into a stirrer, uniformly stirring, adding cement and high-fine slag powder or fly ash, uniformly stirring, adding the pigment, uniformly stirring, adding water, uniformly stirring to obtain a mixture, conveying the mixture to a forming machine, vibrating, extruding and forming the mixture into a pavement brickblank, and putting the pavement brick blank into a curing kiln, carrying out steam curing for at least 8 hours, and taking out of the kiln. The industrial waste residues are adopted to replace natural raw materials to serve as one kind of aggregate, so that the quality of the pavement brick is guaranteed and the hygroscopicity of the pavement brick is improved.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a pavement brick produced by using industrial waste slag and a production method thereof. Background technique [0002] At present, the raw materials for the production of pavement bricks are mainly cement, adding natural sand and gravel as aggregates, and are produced by mixing, molding, curing and other processes. [0003] Concrete pavement bricks are made of cement, gravel, and sand as the main raw materials, and are made into various shapes by processing, pressing or other molding processes. Concrete pavement bricks are mainly used for laying concrete pavements such as urban roads, sidewalks, and urban squares, as well as blocks and slabs for ground engineering. Due to long-term exposure to complex external environments, water erosion, wind corrosion, temperature changes, friction and other reasons, concrete pavement bricks tend to lose their original color and ...
