Burning-free block brick prepared from bulky industrial waste residues

Abstract

The invention relates to a burning-free block brick prepared from bulky industrial waste residues. The burning-free block brick is characterized in that the block brick comprises the following raw materials in parts by weight or volume: 10-80 parts of at least one of tailing, magnesium slag, basic slag, mountain flour, cinder, fly ash, coal gangue, oil shale waste and sulfuric acid slag, 0-80 parts of at least one of gravel, waste sand, construction waste, garbage to be burnt, steel slag, mineral slag, copper slag, iron slag with gold, ardealite, phosphorous slag and carbide slag, 0-50 parts of active cementing material, 0-30 parts of cement clinker, 2-15 parts of cement and a defined amount of water. The preparation method of all types of burning-free and steaming-free standard bricks, perforated bricks, hollow blocks, paving tiles, road edge bricks and fence railings which have low cost and high strength, is as follows: proportioning, stirring for 1-6 minutes, adding a defined amount of water to stir, placing in moulds to form in a machine and performing natural curing for 7-28 days. The burning-free block brick has high raw material selectability, simple technology and wide development and application prospects, and is environmental-friendly.

Description

technical field [0001] The invention relates to a new type of building material, in particular to a new type of non-fired block brick prepared by utilizing bulk industrial waste residues with large displacement, high pollution and difficult treatment, and a preparation method thereof. technical background [0002] With the development of industrialization, a large amount of solid waste is always produced. For example, for every ton of soda ash produced, 9-11 tons of waste residue will be discharged, and for every three tons of shale oil extracted, 97 tons of shale ash will be discharged. my country's mining solid waste has accumulated as many as 10 billion tons, and it is still growing at a rate of no less than 300 million tons per year. If such a large amount of industrial waste is not effectively treated, it will not only bring environmental protection Huge pressure will also bring a heavy burden to industrial development. In today's people-oriented scientific development,...

Problems solved by technology

[0005] At present, there are also some concrete block bricks that mostly need to add a large amount of cement and a variety of expensive additives, which increases the manufacturing cost of concrete block bricks. If the amount of waste is too much, the durability of the block is difficult to guarantee.

There is no report in the field of building materials at home and abroad to prepare low-cost unfired block bricks by using a large volume of waste residue and using a simple process
