Description
Technical field
The invention belongs to building material technical field, and in particular to a kind of concrete with good ductility.
Background technology
Concrete is the widest construction material of modern Application, and it has abundant raw material, cheap, technique is simple, strong
The advantages that degree is high, good endurance.Ready-mixed concrete is one kind of concrete, refers to by cement, gathers materials, water and mixes as needed
The components such as the additive that enters, mineral admixture by a certain percentage mixing plant sold after metering, mixing and use transport vehicle
The concrete mix of place to use is transported at the appointed time.Because site operation has greater environmental impacts, premixing mixes
Solidifying soil receives more and more attention.But existing concrete ductility is poor, after the concrete has set, heat or when being cooled
Expand with heat and contract with cold more serious, underbead crack easily occur, its service life is greatly lowered.
The content of the invention
The purpose of the present invention is to be directed to the problem of existing, there is provided a kind of concrete with good ductility.
The present invention is achieved by the following technical solutions：
A kind of concrete with good ductility, is made up of following component by weight：Cement 78-85, miberal powder 9-13, powder
Coal ash 15-18, sand 200-300, pitch 13-18, coupling agent 1-3, glass fibre 2-5, nitridation titanium valve 1-5, polycarboxylic acids diminishing
Agent 2-6, modified rosin rock ore in sand form 20-30, disecoctylmaleate sodium sulfonate 1-3, water 60-80 containing ethyl cellulose.
Further, the cement is any in portland cement or aluminate cement.
Further, the miberal powder is ground phosphate rock.
Further, the sand fineness is 60-80 mesh.
Further, the coupling agent is that any of titanate coupling agent, organo-silicon coupling agent or two kinds are any mixed
Close.
Further, the glass fiber diameter is 50 μm.
Further, the modified rosin rock ore in sand form preparation method containing ethyl cellulose is：
Pitchstone ore in sand form is crushed, crosses 500 mesh, then evenly spreads in the sulfuric acid solution that mass fraction is 0.15%, matches somebody with somebody
Into the pitchstone ore in sand form suspension that mass fraction is 10.2%, stirring 80min is subsequently placed in microwave reactor at 98 DEG C,
Regulation microwave irradiation power is 800W, and radiation temperature is 60 DEG C, handles 10min；Ethyl cellulose is pressed into 80g：150mL ratio
It is added in absolute ethyl alcohol, mixed liquor is obtained after stirring；The mixed liquor is pressed 1:6 volume ratios are added to by microwave treatment
In pitchstone ore in sand form suspension afterwards, 68 DEG C are heated to, is stirred 2 hours with 1200r/min rotating speeds, then naturally cools to room
Temperature, then filtered, cleaned using deionized water, be dried to constant weight, produced.
The present invention has advantages below compared with prior art：The present invention passes through substantial amounts of experimental study, contains second by addition
The modified rosin rock ore in sand form of base cellulose and the synergy of pitch, the intensity of concrete can not only be effectively improved, simultaneously
Physical features, caking property, response to temperature and the durability of pitch can be changed to a certain extent, pitch can greatly be improved and existed
Extension ability in certain temperature environment, enables adaptation to more weathers, and enables pitch in concrete surface shape
Cheng Genghou adhesive film, surface adhesion performance is improved, the temperature sensitivity of concrete can be especially reduced, not only improve
The ability of anti-deformation of concrete at high temperature, further improve concrete viscoplasticity at low temperature and ductility.By adopting
With the synergy of each raw material in the present invention, the combination property of concrete can be further improved, compression strength and anti-folding are strong
Degree improves more than 10%, and the salt-resistance and impermeability of concrete are further enhanced, moreover it is possible to hinder inside concrete micro-crack
Development, make the effect of concrete activeness and quietness.
