Abstract

A kind of building mortar is mixed according to a certain percentage by coal gangue, slag or flyash and lime, gypsum, cement and silica flour etc.Its advantage is to utilize colliery coal gangue that pile up like a mountain or industrial residue to do the mortar aggregate, so both handled the coal gangue waste material, has solved the shortage in building sand source again, thereby has protected the soil, reduced the pollution of environment.

Description

Building mortar

The present invention relates to a kind of plaster material of architectural usefulness.

At present, wait in the building operation with civilian in industry, lay bricks, build stone, smear seam, the skin and construct the used plaster material in ground and have two kinds of plastering a wall, a kind of is low-grade mortar, is made up of lime and sand; Another kind is the mortar of high grade, is made up of lime, cement and sand or cement and sand, admixes an amount of water and can use.The aggregate of these plaster materials all is based on sand, and some regional sand source is quite difficult, but pile up like a mountain in the area of coal mining a large amount of coal gangues, power plant, Industrial Boiler have a large amount of industrial residues such as a large amount of waste residues and flyash in addition, all these has seriously polluted environment, having occupied the farmland, is present big public hazards.

The objective of the invention is to make full use of coal gangue or industrial residue is produced plaster material for building, be elimination " three wastes " and found an approach, provide a kind of economically viable mortar aggregate for the area that lacks sand again.

This programme is: with the industrial residue fragmentation, sieve into 50-200 purpose particulate state and powdered mixture, then with certain cement, powder gypsum, lime mix mutually, pack, stock, transporting to the construction site can be as ordinary mortar or sand-cement slurry use according to the water cement ratio mix of routine.As in above-mentioned materials, adding the plaster material that a certain amount of silica flour, water reducer etc. are just formed high grade again.

Advantage of the present invention is to make full use of industrial residue such as coal gangue to produce plaster material, has both reduced pollution, has solved the sand source again, has saved the soil.Build a factory that produces ten thousand tons of 3-5 per year, ten thousand yuan of annual return 15-50,2 years recoverable fully investeds.In order to make its cost that is not higher than present mortar, and don't be lower than the label of present mortar, propose the following prescription of implementing:

One, ordinary lime mortar:

Industrial residue 60-80%, gypsum 5-10%, lime 10%, cement 0-5%;

Two, high grade mortar:

Industrial residue 60-80%, gypsum 5-10%, lime 10%, cement 5-10%, silica flour 1-3%, water reducer 0.2-0.5%.

Industrial residue is crushed and screened, standby or with bulk cement carrier sale in bulk with the pack of other material mix.

More than said industrial residue comprise coal gangue, industrial slags, flyash etc., in above prescription, any can batchings separately such as coal gangue, industrial slags, flyash, also can intermingling batching.

Claims

1, a kind of building mortar is characterized in that being made up of industrial residue, gypsum, lime, cement etc.;

2, building mortar as claimed in claim 1, its prescription is: industrial residue 60-80%, gypsum 5-10%, lime 10%, cement 0-5%;

3, a kind of building mortar is characterized in that being made up of industrial residue, gypsum, lime, cement, silica flour and water reducer etc.;

4, building mortar as claimed in claim 1 is characterized in that content is in the prescription: industrial residue 60-80%, gypsum 5-10%, lime 5-10%, cement 0-5%, silica flour 1-3%, water reducer 0.2-0.5%;

5, as claim 1 or 3 described building mortars, it is characterized in that: described industrial residue comprises coal gangue, industrial slags, flyash, and grinding screen is divided into 50-200 purpose particulate state and powdered mixture.Wherein, coal gangue, industrial slags, flyash is any all can prepare burden separately, but also intermingling batching.
