Abstract

This invention relates to a non-fired trowel-free brick. The brick includes (by weight percentage) (1) aggregates from construction demolition waste, discarded rubbish in mixing station, sand and stone in arbitrary composition, 70%-80%, (2) cement as a gelled material 9-15%, (3) fly ash as an admixture 10-18%, and (4) an activator as an additive 1-3%, wherein sodium sulfate 0.8-2.5%, alkaline agent 0.1-0.25%, and caustic soda 0.1-0.25%. The manufactured brick has the advantages of precise geometry, facilitate preparation of various block types and strength grades, high density, low porosity, high strength, and low water-absorption.

Description

A kind of baking-free and the brick of exempting to plaster

Technical field: the invention belongs to building wall brick formula technique field.

Background technology: existing construction wall, usually adopt that mud is baked bricks, cinder concrete and normal concrete brick be as building block, the defective that this class brick exists at present in the use is, rough, degree of compactness is not high, and porosity is bigger, intensity is low, easily suction, " moisture expansion and drying shrinkage makes body of wall produce the crack, and the slag brick of adopting the making of abandoned mine raw material that has in addition also exists outside above-mentioned defective and has certain radioactive harm in appearance.The mud a large amount of land resources of waste of baking bricks, also must fuel fire form ".

Summary of the invention: purpose of the present invention provides a kind of geometric accuracy height for the weak point that overcomes above-mentioned prior art existence just, the preparation of block strength grade kind is convenient, the degree of compactness height, and porosity is low, the intensity height is difficult for the baking-free of suction and the brick of exempting to plaster.

The objective of the invention is to realize by following technical solution:

A kind of baking-free and the brick of exempting to plaster is characterized in that, it includes following component (weight percent): 1, aggregate: building removal rubbish, stirring station discarded rubbish, sand and building stones; 2, gelling material: cement; 3, adulterant: flyash; 4, additive: exciting agent, wherein: aggregate for three kinds of material in building removal rubbish, stirring station discarded rubbish, sand and the building stones in arrangement and the arbitrary combination on the weight, when adopting sand and building stones in the aggregate, the proportioning of sand and building stones is that sand accounts for 40%-60%, building stones account for 60%-40%, and the gross weight of aggregate in whole prescription is 70%-80%; Cement is 9-15%; Flyash 10-18%; Exciting agent is 1-3%, wherein, and Sodium sulfate anhydrous.min(99) 0.8-2.5%, buck agent 0.1-0.25%, caustic soda 0.1-0.25%.

Because the rubbish of building removal is at present mainly drawn toward the countryside to outwell, both wasted also contaminate environment of resource, with its use manufacture non-burning brick, really be to kill two birds with one stone, under the little situation of building waste amount, can adopt sand and building stones as main aggregate of the present invention, in building removal rubbish, should not contain plastics, glass, reinforcing bar and timber goods; And the discarded rubbish that concrete stirring station produces, amount is bigger at present, also is the good aggregate raw material of the present invention.But the present invention builds removal rubbish, the discarded rubbish of stirring station, sand and three kinds of material of building stones arbitrary combination, promptly building removal rubbish, the discarded rubbish of stirring station, sand and three kinds of material of building stones can mix simultaneously as aggregate, also can be by building removal rubbish, the discarded two kinds of material of rubbish of stirring station as aggregate, also can also can discard rubbish, sand and two kinds of material of building stones as aggregate by building removal rubbish, sand and two kinds of material of building stones as aggregate by stirring station.And but three kinds of material arbitrary combination also can be the arbitrary combination of three kinds of material on weight.

Become particle diameter in 1cm above-mentioned main selected aggregate raw material pulverizing, become the concrete of dry low wash water after the proportion relation mixing and stirring by prescription, be that the water mixing of per kilogram compound is not higher than 0.15 kilogram, have on directly perceived that clutch can be agglomerating, unclamp the agglomerating effect of scattering of hand, the process of making brick of the present invention is: the platform by equipment shakes, mould shakes and high pressure, three-dimensional integrated co-operation mode adopts the compound extrusion pressing type then steam curing and dispatches from the factory after static naturally maintenance 25-32 days.The squeeze of forming pressure is generally 200 tons-300 tons.

The present invention is owing to adopt unique proportioning raw materials to mix, behind vibration and highly compressed production technique compacted under, make the ratio of precision of its geometrical dimension higher, smooth surface is smooth, in construction process, control the vertical planeness of masonry easily, directly frictioning putty can reach senior plastering quality standard, the brick body has at the bottom of the porosity because of its prescription relation, the intensity height, be difficult for producing fissured advantage, owing to no longer need to plaster, just need not water in the masonry surface, avoided the common quality defect of building block " moisture expansion and drying shrinkage ", also avoided simultaneously because of the generation hollowing of plastering, cracking, common wall quality problems such as shelling make the construction period obtain greatly shortening, and have also saved the cost consumption of plastering and producing.

Further set forth content of the present invention below in conjunction with embodiment.

Specific embodiments

Embodiment one, select for use building removal rubbish, the discarded rubbish of stirring station, three kinds of material whiles of sand and building stones as aggregate; 2, gelling material adopts cement; 3, adulterant adopts flyash; 4, additive adopts exciting agent, and wherein prescription is (weight percent): the building removal rubbish as aggregate is 70%, wherein builds removal rubbish and accounts for 30%, and the discarded rubbish of stirring station accounts for 30%, and sand and building stones account for 10%, and its medium sand accounts for 5%, and building stones account for 5%; Cement is 15%; Flyash 13%; Exciting agent is 2%, wherein, and Sodium sulfate anhydrous.min(99) 1.5%, buck agent 0.25%, caustic soda 0.25%.

Embodiment two, select for use sand and building stones as aggregate; 2, gelling material: cement; 3, adulterant: flyash; 4, additive: exciting agent, wherein prescription is (weight percent): as the sand of aggregate and the gross weight of building stones is 80%, and its medium sand accounts for 32%, and building stones account for 48%; Cement is 9%; Flyash 10%; Exciting agent is 1%, wherein, and Sodium sulfate anhydrous.min(99) 0.8%, buck agent 0.1%, caustic soda 0.1%.
