Abstract
The present invention features that the building brick is produced with steel slag 50-95 wt%, flyash 5-40 wt%, cement 0-10 wt% and water 5-6 wt%, and through the steps of mixing the materials in a stirrer, vibrating and pressing to form in a brick making machine, stacking and curing for 7-28 days. The brick has high strength, low production cost, high product quality and good anti-freezing performance.
Description
Technical field
The present invention relates to a kind of building brick, particularly a kind of manufacture method of utilizing the building brick without firing and steaming of industrial residue manufacturing.
Background technology
The brick that present construction wall is used mostly adopts clay to make through sintering, produces arable land, farmland but also consumes energy cost height that this brick is not only wasted a large amount of preciousnesses.
In recent years, in order to replace the clay brick of firing, people develop the non-burning brick of multiple non-clay manufacturing, and utilize industrial waste to make building brick to reach purpose of energy saving, for example disclosed among the CN1049490 " making non-burning brick method and binding agent " with industrial residue, the composition of this brick has slag, flyash, cement, this method need add 2%～10% lime in prescription, and the ratio of slag is not high yet, CN 1093688 discloses " pure industrial residue no-baked no-steamed building bearing brick and furring tile and preparation method thereof ", this its flyash 35～60% slags 20%～50% of building brick that do not add cement are processed 15%～30% carbide slag and a certain amount of chemosetting hardening accelerator in addition, because carbide slag produces chemical reaction in air, time, long meeting produced weathering, and the intensity of brick is affected, other adopts slag, the method of raw material production building bricks such as flyash generally also need be established curing room, drying room etc.
In addition, slag, the flyash equal industrial residue that discharge in ironmaking at present, steel-making, power station are not fully utilized, and cause environmental pollution.
Summary of the invention
Purpose of the present invention mainly is to solve existing building with the low problem of brickwork industry waste residue utilization rate, and a kind of lime, carbide slag and binding agent do not mixed is provided, and need not establish the building brick without firing and steaming and the manufacture method of utilizing industrial residue to make of curing kilns again.
The object of the present invention is achieved like this, and the weight percent of this building brick composition is a slag 50%～95%, flyash 5%～40%, cement 0%～10%.
Concrete scheme of the present invention has, and the weight percent of producing the building brick composition is a slag 75%～85%, flyash 10%～25%, cement 3%～5%.
The slag of its raw material of the present invention is the waste residue of ironmaking, steel-making discharging; Flyash is the dust of heat power plant's discharging, below the granularity 15mm of its slag.
Production method of the present invention is for dropping into waste steel slag, flyash, cement in the stirrer simultaneously by proportioning raw materials, the water of adding 5%～6%, stir, it is molded to shake through brick press then, piled bricks maintenance after the moulding, maintenance 7～28 days, it forces the present invention to stir, supplies water and finish in a planetary mixer.
The present invention also can the production building block, precoated plate etc.
Advantage of the present invention and effect be, makes full use of waste steel slag, flyash, turns waste into wealth, and do not add materials such as lime, carbide slag, binding agent, hardening accelerator, curing room, drying room need be set, save energy, utilize the high advantage of slag later strength, the add-on of slag is big, makes this building brick intensity higher, and production cost is low, good product quality, its every technical indicator reaches the standard of national building brick, and the frost resistance of this building brick is good, is particularly suitable for northern area and uses.
Embodiment
The weight percent of this building brick composition of the present invention is a slag 50%～95%, flyash 5%～40%, cement 0%～10%.
The slag of its raw material of the present invention is the waste residue of ironmaking, steel-making discharging; Flyash is the dust of heat power plant's discharging, getting weight percent is slag 75%～85%, below the granularity 15mm, and flyash 10%～25%, cement 3%～5% is raw material, in the input planetary stirring machine, add 6% water, stir mixing, brick press shakes molded then, artificial maintenance during brick is placed in the open after the moulding, maintenance 7～28 days reached complete intensity after 28 days.
Be two specific embodiments of the present invention below
| Embodiment 1 | Embodiment 2 | ||
| Proportioning raw materials (weight) | Slag % | 80 | 66 |
| Flyash % | 10 | 27 | |
| Cement % | 10 | 7 | |
| Detected result | Ultimate compression strength Mpa | 20.6 | 16.4 |
