Abstract
The invention discloses a kind of pressure-resistant antidetonation foam concrete block and preparation method thereof, it is related to building material technical field, the building block includes following raw material：Carbide slurry, modified landplaster, steel-making slag powder, bauxite, basalt fibre, Alumina gel, light calcined magnesia, baryta fledspar powder, organic silicon emulsion, foaming agent, foam stabilizer, water reducer, adjustable solidification agent and early strength agent.Its preparation method is that raw material is stirred to mixing stage by stage, is poured into a mould afterwards, just maintenance is handled and steam press maintenance.The foam concrete block cost of material of the present invention is low, prepare simple and convenient, not only unit weight is light, heat insulation sound absorbent is good, and greatly improved in mechanical property, the problem of especially solving the pressure-resistant toughness of concrete segment in the prior art and poor shock resistance, the service life of building block is extended, with wide market prospects.
Description
Technical field
The present invention relates to building material technical field, and in particular to a kind of pressure-resistant antidetonation foam concrete block and its preparation
Method.
Background technology
With the development of urban construction, modernization of the housing industry is gradually formed, and the quality and function to materials for wall will
Ask also more and more high.Although having all kinds of air-entrained concrete building blocks on the market at present, the environment-friendly energy-saving wall such as light wall board
Material, but the factors such as raw material, the technique of product in itself are limited to, still there are a variety of drawbacks and inborn defect.Urban construction, it is special
It is not that middle and high layer building is badly in need of a large amount of high-quality, multi-functional high-quality new wall material.
Novel wall material foam concrete block is as a kind of low energy consumption, environment-friendly type New Building Materials, very
Meet the policy requirements of country, it has a premium properties such as intensity height, light weight, waterproof thermal-insulated, but current existing aerating
The problem of concrete segment has pressure-resistant toughness and poor shock resistance, drastically influence foam concrete block in architectural engineering
Service life and security reliability.
To solve above-mentioned problem, domestic people in the industry and person skilled have done many effort, including change
The match ratio of its raw material, using additive, changes the methods such as production technology, although have certain effect, but have its limitation.
In a word, concrete also be unable to do without the development of concrete segment materials and technique, be unable to do without the hair of the engineer applied object of concrete
Exhibition change.Therefore, the performance for further improving foam concrete block is particularly necessary.
The content of the invention
For problems of the prior art, the invention provides a kind of pressure-resistant antidetonation foam concrete block and its system
Preparation Method, this kind of concrete segment cost of material is low, prepares simple and convenient, and not only unit weight is light, heat insulation sound absorbent is good, Er Qie
Greatly improved in mechanical property, the problem of especially solving the pressure-resistant toughness of concrete segment in the prior art and poor shock resistance,
The service life of building block is extended, with wide market prospects.
In order to achieve the above object, the present invention is achieved through the following technical solutions：
A kind of pressure-resistant antidetonation foam concrete block, including following raw material by weight：60-80 parts of carbide slurry, change
40-60 parts of land plaster of property, 15-25 parts of steel-making slag powder, 20-30 parts of bauxite, 5-15 parts of basalt fibre, Alumina gel 5-15
Part, 10-20 parts of light calcined magnesia, 10-20 parts of baryta fledspar powder, 4-8 parts of organic silicon emulsion, 1-5 parts of foaming agent, 1-5 parts of adjustable solidification agent
With 1-5 parts of early strength agent；
The modified landplaster is made by following steps：Gypsum is put into sodium carbonate with being soaked in potassium permanganate mixed solution
Steep after 2-4h, take out drying, add Silane coupling agent KH550 equivalent to laumontite weight 2-4%, equivalent to laumontite weight
1-3% sldium lauryl sulfate and aluminum oxide equivalent to laumontite weight 1-3% under 300-500r/min in stirring 20-
Ground after 30min, cross 120-160 mesh sieves and produce.
Further, the concrete segment includes following raw material by weight：70 parts of carbide slurry, modified landplaster
50 parts, 20 parts of steel-making slag powder, 25 parts of bauxite, 10 parts of basalt fibre, 10 parts of Alumina gel, 15 parts of light calcined magnesia, barium it is long
3 parts of 15 parts of stone flour, 6 parts of organic silicon emulsion, 3 parts of foaming agent, 3 parts of adjustable solidification agent and early strength agent.
Further, the modified landplaster is made by following steps：Gypsum is put into sodium carbonate to mix with potassium permanganate
Close in solution after immersion 3h, taking-up drying is added equivalent to the Silane coupling agent KH550 of laumontite weight 3%, equivalent to turbid boiling
The sldium lauryl sulfate of stone weight 2% and equivalent to laumontite weight 2% aluminum oxide under 400r/min stir 25min after grind
Mill, crosses 140 mesh sieves and produces.
It is preferred that, the foaming agent is one kind in sodium azodiisobutyronitrile, lauryl sodium sulfate or sodium metasilicate.
It is preferred that, the adjustable solidification agent is one kind in barium hydroxide, sodium tripolyphosphate or protein salt retarder.
It is preferred that, the early strength agent be calcium nitrate, calcium chloride, potassium sulfate, sodium chloride, aluminium chloride or sodium sulphate at least
Two kinds.
A kind of preparation method of above-mentioned pressure-resistant antidetonation foam concrete block, is followed the steps below：
(1) raw material is weighed by the weight；
(2) carbide slurry, bauxite, basalt fibre, Alumina gel and light calcined magnesia are delivered in mixer and stirred
Mixing 40-50min is mixed, speed of agitator is 70-80r/min, obtains batch mixing A；By modified landplaster, steel-making slag powder, baryta fledspar powder and have
