Abstract

The invention provides non-autoclaved sand-lime bricks. The non-autoclaved sand-lime bricks are manufactured from, by weight, 42.5 bulk cement 10%-15%, coal gangue powder 20%-30%, slag 6%-14%, pebbles with the diameter smaller than or equal to 5 cm 6%-14%, mineral powder 25%-35%, fine sand 3%-7%, an early strength agent 0.005%-0.015% and the balance waste. The non-autoclaved sand-lime bricks are manufactured by adopting industrial waste under normal temperature and pressure, burn-free and non-autoclaved conditions, the advantages of non-high-temperature calcinations and no land resource waste of autoclaved sand-lime bricks are kept, expensive equipment facilities including industrial steam boilers, pressure pipelines, autoclaving kettles, rail cars and the like requiring high investment are not needed, and the non-autoclaved sand-lime bricks are small in investment, low in cost, simple in process, capable of saving energy and environmentally friendly.

Description

One exempts from autoclaved lime-sand brick and preparation method thereof

Technical field

The present invention relates to building material field, particularly relate to one and exempt from autoclaved lime-sand brick and preparation method thereof.

Background technology

Brick in the market mainly includes clay brick, cement brick and steam-pressing brisk three kinds.Being compared as follows of these three brick:

Clay brick be history at most, most widely used refractory material, manufacture clay brick raw material be clay mineral, natural resistance to Fire clay generally can be divided into hard paste and mild-clay, and in refractory material manufacturing process, the former is most of is used as after calcining Grog；After the latter adds water, plasticity is good, easily sinters, and multiplex makees bonding agent.But traditional clay brick need to take a large amount of preciousness Cultivated land resource also consumes fuel energy the most in short supply, is prohibited production and application by country.

Cement brick technique is simply easy to do, and by directly stirring vibration, natural drying, nourishment form.Than steaming on process equipment Pressure brick is simply a lot, and selling price is on the low side, and profit is the highest, and more with workman, takies production site area bigger.

Autoclaved lime-sand brick be with flyash, cinder, gangue, mine tailings, residue of chemical industry or natural sand, tidal land mud etc. (more than One or several of raw material) as primary raw material, a kind of novel wall material brick manufactured without high-temperature calcination.Autoclaved lime-sand brick Prepare through blank, compressing, form through autoclaving.Autoclaved lime-sand brick is that a kind of technology maturation, function admirable save again The New Building Materials of energy, it is applicable to the bearing wall of multistory masonry structure building.This autoclaved lime-sand brick is the completeest on raw material Complete utilization industrial residue, and still need to consume certain steam energy, need to use expensive commercial vapor boiler, manometer tube The installations and facilities such as road, still kettle, railcar, cause investing big, cost height, complex process and energy-conserving and environment-protective not.

Summary of the invention

For defect present in above-mentioned prior art, it is desirable to provide one exempts from autoclaved lime-sand brick and preparation method thereof, should Exempt from autoclaved lime-sand brick use industrial waste, normal temperature and pressure, free of calcining and steam curing under conditions of be made, not only maintain steam pressure ash Sanded brick, without high-temperature calcination, the advantage of not wasting land resource, is more not required to the expensive commercial vapor boiler of investment price, manometer tube The installations and facilities such as road, still kettle, railcar, invest that little, with low cost, technique is simple, energy-conserving and environment-protective.

The present invention adopts the following technical scheme that

One exempts from autoclaved lime-sand brick, it is characterised in that: this autoclaved lime-sand brick of exempting from includes raw material: 42.5 bulk cement 10%-15% (weight ratio), colliery powder 20%-30% (weight ratio), slag 6%-14% (weight ratio), diameter≤5cm cobble 6%-14% (weight ratio), mineral powder 25%-35% (weight ratio), the husky 3%-7% (weight ratio) of essence, early strength agent 0.005%-0.015% (weight Amount than), clout be waste material.

Further, the optional raw material being equipped with down one or more of described clout: antifreezing agent 0.01%-0.1% (weight ratio), Vitreous hoodle is appropriate or building waste is appropriate.

Further, this autoclaved lime-sand brick of exempting from includes the raw material of following weight or volume ratio: 42.5 bulk cement 12% (weight Than), colliery powder 25% (weight ratio), slag 10% (weight ratio), diameter≤5cm cobble 10% (weight ratio), mineral powder 32% (weight ratio), essence husky 5% (weight ratio), early strength agent 0.01% (weight ratio), clout 5.94% (weight ratio).

Further, exempt from autoclaved lime-sand brick described in and include antifreezing agent 0.05% (weight ratio).

Further, the manufacture method exempting from autoclaved lime-sand brick described in is:

Step one, after raw material mix homogeneously, sorted screen cloth, and filtered out diameter and be not suitable for the raw material of brickmaking more than 5cm；

Step 2, utilize forklift that raw material transport is transported to material machine；

Step 3, feeder, be promoted to blender hopper by the raw material arranged in pairs or groups in proportion, and various raw materials are abundant by blender Stir；

Step 4, will be stirred by belt conveyor after feedstock transportation to brickmaking machine hopper；

Step 5, brick forming machine upper and lower mould is utilized to be pressed into adobe；

Step 6, natural curing, adobe is transported to indoor piling neat after, by watering the appropriate wet water curing of pouring；

About step 7,7 working days of maintenance, it is thus achieved that finished product, dispatch from the factory.

Beneficial effects of the present invention:

Compared with prior art, the one that the present invention provides exempts from autoclaved lime-sand brick and preparation method thereof, and this is exempted from autoclaved lime-sand brick and uses Industrial waste, normal temperature and pressure, free of calcining and steam curing under conditions of be made, not only maintain autoclaved lime-sand brick without high-temperature calcination, The advantage not wasting land resource, is more not required to the expensive commercial vapor boiler of investment price, pressure pipeline, still kettle, railcar Etc. installations and facilities, invest that little, with low cost, technique is simple, energy-conserving and environment-protective.
