Abstract
The invention discloses concrete castable for buildings. The castable comprises a main material and cement padding, wherein the main material is formed by sintering and smashing clay, aluminum ash, iron mine waste residue and an auxiliary material; weights of the aluminum ash, the iron mine waste residue and the auxiliary material respectively account for 30-40%, 20-25% and 15-20% of the weight of the clay; and the auxiliary material is formed by mixing bone meal, carbon powder and calcium carbonate particle with the fineness of 8-20 meshes in the weight ratio of 1:(5-10):(20-30). According to the castable disclosed by the invention, the main material formed by firing the aluminum ash, the iron mine waste residue, the clay and the auxiliary material is adopted to replace a part of cement to participate in the mixing of concrete, the cement consumption is reduced and during mixing, the cement is solidified after entering gaps and channels of the main material, so that the combinability and the crosslinking property of the cement and the main material are increased and the fracture resistance and seismic resistance of the finally produced concrete castable are increased.
Description
Technical field
The present invention relates to the concrete depositing material of building field, specifically a kind of build concrete mould material and preparation method thereof.
Background technology
Concrete is one of contemporary topmost civil engineering material, is generally by cement, coarse aggregate (rubble or cobble), fine aggregate (sand), admixture and water mix, through a kind of artificial stone-like material of sclerosis.Sand, stone play skeleton function in concrete, and suppress the contraction of cement; Cement and water form grout, are wrapped in the space of coarse-fine aggregate surface also between filler aggregate.Cement slurry is lubricate upon hardening, makes concrete mix have works fine performance, after sclerosis, aggregate is cemented together, forms strong entirety.
Concrete of the prior art adopts cement to carry out mix in a large number, cause the usage quantity of cement to increase, and the production process of cement can cause a series of pollution to environment, and the increase of cement usage quantity also just result in the deterioration of environment indirectly; Meanwhile, also there is anti-folding and the not high problem of anti-seismic performance in existing concrete.
Summary of the invention
A large amount of cement mix is adopted to cause the large and anti-folding of cement usage quantity and the not high problem of anti-seismic performance for solving the concrete pouring material of prior art, the invention provides a kind of build concrete mould material and preparation method thereof, employing aluminium ash, iron ore waste residue, clay and auxiliary material etc. make major ingredient to replace the cement of part, aluminium ash, iron ore residue resource that not only suitable utilization is discarded, decrease the usage quantity of cement, and also improve concrete anti-folding and anti-seismic performance.
The present invention is the technical scheme solving the problems of the technologies described above employing: a kind of build concrete mould material, comprise major ingredient and cement filler, described major ingredient is pulverized after being sintered by clay, aluminium ash, iron ore waste residue and auxiliary material and is formed, wherein, the weight of aluminium ash, iron ore waste residue and auxiliary material is respectively 30-40%, 20-25% and 15-20% of clay weight.
The ratio of described auxiliary material is bone meal, carbon dust and fineness to be 8-20 object calcium carbonate granule with weight ratio be 1:5-10:20-30 mixes.
The preparation method of above-mentioned build concrete mould material, comprises the following steps:
The preparation of step one, auxiliary material
By bone meal, carbon dust and fineness be 8-20 object calcium carbonate granule according to above-mentioned ratio mixing and stirring, make auxiliary material, for subsequent use;
Step 2, the auxiliary material prepared in step one and clay, aluminium ash and iron ore waste residue are mixed after obtain compound, for subsequent use;
Wherein, the weight of aluminium ash, iron ore waste residue and auxiliary material is respectively 30-40%, 20-25% and 15-20% of clay weight;
Step 3, to be sent in stove by the compound in step 2 and fire in three stages, sintering procedure is as follows:
1) intensification pre-burning
The temperature controlled in stove rises to 160-180 DEG C, and keeps this temperature 2-3h in 1-2h, and then kiln temperature is risen to 950-1000 DEG C, and keeps this temperature 3-5h;
2) constant temperature is fired
Kiln temperature is risen to 1300-1500 DEG C, keeps this temperature 5-7h;
3) cooling down
Stop heating and pass into normal temperature air in kiln, namely completing after being cooled to normal temperature and fire, material is milled to 0.5-5mm and namely obtains major ingredient;
In use, stir can construct adding suitable quantity of water after major ingredient and cement filler mixing.
In the intensification pre-burning stage of described step 3, stove inside is kept to have unimpeded exhaust-duct with extraneous.
When constructing, also need to add sand particles or reinforcing bar when major ingredient mixes with cement filler as skeleton.
In use, select the weight ratio of cement and major ingredient as required, generally, the weight ratio of cement and major ingredient is chosen as 3-5:1 in the present invention.
In the present invention, carbonic acid gas and calcium oxide is produced because the carbon dust that contains in auxiliary material and calcium carbonate powders at high temperature decompose, thus generation space, decompose the calcium oxide produced at high temperature to react with the aluminum oxide in the silicon oxide in clay, aluminium ash and the Z 250 in iron ore waste residue, the pin of administration measure, the mullite crystal of column and be similar to the vitreous state of spinel structure, thus significantly improve the intensity of major ingredient; Bone meal at high temperature promotes that each material is as calcium oxide, aluminium ash, perviousness between iron ore waste residue and clay (especially aluminium ash infiltrates through in the portion void of rest materials), thus makes high temperature sintering be more easily react; Meanwhile, heat is released in the oxidation of carbon, helps inner sintering on the one hand, some impurity component scaling loss of clay can be fallen on the other hand; Because the major ingredient inside after having sintered is full of space, when with cement mix, cement can to enter in these passages and space thus to play crosslinked effect, has increased substantially and has solidified rear concrete anti-folding and anti-seismic performance.
Beneficial effect: the present invention, compared with existing concrete pouring material, has the following advantages:
1) at high temperature the combustion oxidation of carbon dust and the decomposition of calcium carbonate can leave space, when the existence of these spaces and passage ensure that cement mix and major ingredient possess better crosslinked action;
2) calcium oxide produced after Decomposition of Calcium Carbonate at high temperature reacts with the aluminum oxide in the silicon oxide in clay, aluminium ash and the Z 250 in iron ore waste residue, the pin of administration measure, the mullite crystal of column and be similar to the vitreous state of spinel structure, thus significantly improve the intensity of major ingredient; Meanwhile, because contraction during sintering can expand original space, further increase porosity, when being convenient to mix, cement enters;
3) the present invention adopts discarded aluminium ash, iron ore waste residue to prepare major ingredient, then major ingredient is used to replace a part of cement to participate in concrete mix, not only reduce the consumption of cement, and when mixing, cement to enter in the space of major ingredient and passage and solidifies, thus enhance associativity and the bridging property of cement and major ingredient, and then improve the anti-folding of concrete pouring material and the anti-seismic performance of final production.
