Abstract
The invention discloses a kind of strong concrete, it is characterized in that, be made up of the raw material of following weight part: cement 105-140, stone 90-120, carboxylic styrene butadiene latex 9-13, pitch 8-14, sodium-chlor 6-9, Sodium Nitrite 7-10, gypsum 20-35, asbestos 13-15, dipropylenetriamine 9-12, blast-furnace slag 95-120, iron ore tailings 80-100, waste and old clothes 50-60, auxiliary agent 3-6, suitable quantity of water; The present invention utilizes the rejected material such as blast-furnace slag, iron ore tailings, and the cement concrete produced by optimization of C/C composites has the advantages such as ultimate compression strength is high, good endurance, workability are good, high temperature resistant.
Description
Technical field
The present invention relates to building concrete technical field, be specifically related to a kind of strong concrete and preparation method thereof.
Background technology
Concrete normally makes gelling material with cement, sand, masonry gather materials, coordinate by a certain percentage with water (can admixture and adulterant be contained), the cement concrete obtained through stirring, also normal concrete is claimed, it has that easy-formation, energy consumption are 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 material of construction, plays a very important role the development of human society
As concrete must the consumption that gather materials of one of addition material very large, natural aggregate overexploitation, make it quality and also cannot meet the demand that existing concrete produces, also there is intensity difference in current concrete, frost resistance is low, dry shrinkage is large, easily the deficiency such as generation cracking.Therefore, develop various artificial aggregate and find suitable substitute material, thus develop a kind of high strength, frost resistance is good, dry shrinkage is little, the new concrete of not easy to crack, the antibacterial function such as heat-resisting, becomes the technical barrier being badly in need of solving in this area with the needs meeting high quality construction project.
In recent years, along with growth in the living standard and social progress, the various solid waste that people's daily life and Industrial processes produce and urban construction are removed and are remake the living environment that the solid waste etc. brought annoyings resident always, and the process that more particularly can not continue the waste and old clothes worn is a difficult problem always.Solid waste is added in concrete as starting material by the present invention, achieves the cyclic utilization of waste, decreases the pollution to environment, meets strategy of sustainable development requirement.
Summary of the invention
Object of the present invention is just to provide a kind of strong concrete and preparation method thereof, to overcome the deficiencies in the prior art.
The object of the present invention is achieved like this:
A kind of strong concrete, it is characterized in that, be made up of the raw material of following weight part: cement 105-140, stone 90-120, carboxylic styrene butadiene latex 9-13, pitch 8-14, sodium-chlor 6-9, Sodium Nitrite 7-10, gypsum 20-35, asbestos 13-15, dipropylenetriamine 9-12, blast-furnace slag 95-120, iron ore tailings 80-100, waste and old clothes 50-60, auxiliary agent 3-6, suitable quantity of water.

The preparation method of described a kind of strong concrete, is characterized in that comprising the following steps:
(1) after waste and old clothes being cleaned up accessories such as dismounting button, slide fastener etc., tear and make the fiber reinforced cement composite of being entangled with of bulk become flocculence, the fiber making about 5-10mm long is for subsequent use;
(2) calcined at 650-850 DEG C by iron ore tailings after 3-6 hour and take out pulverizing, add dipropylenetriamine, carboxylic styrene butadiene latex, asbestos and suitable quantity of water and stir 30-40 minute, mixing, granulation, balling-up particle diameter is at 5-8mm;
(3) pitch, gypsum and blast-furnace slag are put into 1 ‰ iron(ic) chloride and 0.5 ‰ calcium chloride composite solutions flood 10-12 hour, take out and dry, be pulverized and mixed evenly;
(4) step (1), (2), (3) reaction mass and other leftover materials are added suitable quantity of water stirring to mix and get final product for 5-8 minute.
The present invention has following beneficial effect: the present invention utilizes the rejected material such as blast-furnace slag, iron ore tailings, the cement concrete produced by optimization of C/C composites has the advantages such as ultimate compression strength is high, good endurance, workability are good, high temperature resistant, can be used for the various engineerings under high level, large span and mal-condition environment.
