Description

A kind of refractory concrete and preparation method thereof
Technical field
The present invention relates to building concrete technical field, be specifically related to a kind of refractory concrete and preparation method thereof.
Background technology
Concrete usually makes Binder Materials with cement, sand, masonry gather materials, coordinate by a certain percentage with water (can containing additive and admixture), agitated and the cement concrete that obtains, also referred to as normal concrete, it has that easy-formation, energy consumption be low, good endurance, low price and be combined the advantage that can be made into various support mechanism with steel, is contemporary most widely used construction material, the development of human society is played a very important role
As concrete must the consumption that gather materials of one of additive very big, natural aggregate exhaustive exploitation, so as to quality also cannot meet the demand that existing concrete produces, current concrete there is also intensity difference, frost resistance is low, dry shrinkage is big, easily the deficiency such as generation cracking. Therefore, develop various artificial aggregate and find suitable substitute material, thus develop a kind of high intensity, freexing tolerance is good, dry shrinkage is little, the new concrete of the function such as heat-resisting not easy to crack, antibacterial, the needs to meet high-quality construction project become the technical barrier that this area is badly in need of solving.
In recent years, along with growth in the living standard and social progress, various solid wastes that people's daily life and industrial processes produce and urban construction are removed and are remake the solid waste etc. brought and annoying the living environment of resident always, and the process of waste and old clothes that more particularly can not continue to wear is always up a difficult problem. Solid waste is added in concrete as raw material by the present invention, it is achieved that the cyclic utilization of waste, decreases the pollution to environment, meets strategy of sustainable development requirement.
Summary of the invention
It is an object of the invention to provide a kind of refractory concrete and preparation method thereof, to overcome the deficiencies in the prior art.
The object of the present invention is achieved like this:

Described auxiliary agent is made up of following raw materials in part by weight: Kaolin 7-12, Oleum Verniciae fordii 2-4, carbamide 10-13, Cortex Meliae 9-11, aluminium hydroxide 9-13, discarded glass 4-7, dodecylbenzene sodium sulfonate 0.03-0.07, magnesium powder 0.02-0.04, ultra micro wax powder 0.3-0.6, Colophonium 2-5, Flos Rosae Rugosae quintessence oil 0.03-0.07, its preparation method is to be mixed by each crushing material, add suitable quantity of water to stir 30-40 minute, pelletize, balling-up particle diameter is in 2-5mm, drying.
The preparation method of described a kind of refractory concrete, it is characterised in that comprise the following steps:
(1) after waste and old clothes is cleaned up the dismounting accessories such as button, slide fastener, tear and make the fiber reinforced cement composite of being entangled with of bulk become flocculence, make fiber long for about 5-10mm standby;
(2) take out after calcining 3-6 hour at bentonite, quartz sand one being arised from 625-835 DEG C and pulverize, add polycrystalline mullite fibre, calcium formate, dodecyl sodium sulfate and suitable quantity of water and stir 30-40 minute, mixing, pelletize, balling-up particle diameter is at 5-8mm;
(3) asphalt road waste residue is put in 1 ‰ iron chloride and 0.5 ‰ calcium chloride composite solutions and impregnate 10-12 hour, take out nature and dry;
(4) step (1) (2), (3) reaction mass and other leftover materials add suitable quantity of water stirring within 5-8 minute, mix and get final product.
The present invention has following beneficial effect: containing asphalt road waste residue in the concrete aggregate that the present invention prepares, decrease the consumption of natural sandstone, reduce production cost, polycrystalline mullite fibre and waste and old garment fabric are added in the raw material of the present invention, add concrete toughness and heat-insulating property, make the concrete prepared not easy to crack, workability is good, there is resistance to elevated temperatures, improve concrete pore structure and hole grating, improve concrete impermeability.
