Description
Technical field
The invention belongs to materialogy fields, are related to a kind of composite material for building, increase more particularly, to a kind of assorted fibre
The strong superelevation ductility cement-based material of tough superelevation.
Background technology
For concrete as the construction material being most widely used in the world today, it is relatively low high with brittleness that there are bending strengths
Disadvantage is also easy to produce crack so as to cause concrete and is even broken in use, seriously affects the whole peace of building or structures
Complete and service life.Some a large amount of existing building structure and position in modern architecture, such as high ferro overpass, large span it is over strait and
At the bridge floor of river-spanning bridge, expansion joint and high-rise building key node, since its ambient stress is complicated harsh, it is necessary to use
Bending resistance, tensile strength and ductility high-strength high ductility concrete material as high as possible.
It is more than 120MPa's that ultra-high performance concrete (Ultra-high performance concrete UHPC), which has,
Compression strength, and the bending strength more than 20MPa.Patent of invention ZL201510026894.6 uses a diameter of 0.12-
0.22mm, length 6-14mm, tensile strength are more than the steel fibre of 2000MPa as toughening material, and a kind of superelevation is prepared
Toughness concrete, 28 days bending strengths are 20-40MPa, compression strength 120-180MPa.Patent of invention
Using polyacrylonitrile fibre and steel fibre, as toughening material, a kind of high tenacity coagulation is prepared in ZL201210566338.4
Soil, 28 days optimal bending strengths are 8.6MPa.Patent of invention 201110323697.2 discloses a kind of concrete and its preparation
Method.The concrete includes cementitious material, river sand, high efficiency water reducing agent, water, steel fibre and polypropylene fibre.Anti- folding is strong within its 28 days
Degree is 17.1-18.6MPa.Above-mentioned height (superelevation) toughness concrete patent of invention only focuses on intensity (compression strength, bending strength)
Index does not have the relevant parameter for directly embodying its toughness index actually, still falls within the concrete of traditional field.
Invention content
It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide a kind of solution prior arts
In concrete high-tensile, high compressive strength and high ductility are difficult to the technical barrier coexisted, and its slump is made to be more than
The cement-base composite material of 180mm, it is pumpable cast-in-place.
The purpose of the present invention can be achieved through the following technical solutions:
A kind of strong superelevation ductility cement-based material of the superelevation of assorted fibre toughening, including following components and parts by weight content
Raw material:
525 Portland cements:700~1250,

Super-high strength steel fiber:39-117.
The superhigh molecular weight polyethylene fibers length be 6-24mm, a diameter of 15-40 μm, tensile strength 1800-
3900MPa, elasticity modulus 40-150GPa, limit elongation 2%-5%, draw ratio are more than 400.
The superhigh intensity steel fibre is straight fiber or with hook fiber, length 6-13mm, diameter 0.115-0.2mm,
Tensile strength is 2700MPa, elasticity modulus 200GPa, limit elongation 2%-3%.
The mesh number of the quartz sand is 70~120 mesh, and cement mortar rate is no more than 0.5, controls the fracture toughness of matrix.
The size controlling of the silicon ash plays the role of filling and promotes aquation at 0.1-0.2 μm.
The miberal powder be size controlling at 1-20 μm, play good filling effect.
The stretcher strain ability for the strong superelevation ductility cement-based material of superelevation being prepared is 1%~10%, tensile strength
For 8MPa~15MPa;Bending strength:20-50MPa;Compression strength is 100MPa~200MPa.
Compared with prior art, the present invention is based on Micromechanics design principles, high by superelevation compression strength 120-200MPa
Tensile strength 8MPa~15MPa and the drawability 1%-10% of highly resistance are combined, and composite material has good mobility, pumpable
Sending can be cast-in-place.
In the present invention, raw material do not include coarse aggregate, and have used active better miberal powder to replace flyash.In addition,
Silicon ash is also used in the preparation of material, the active SO in both mineral spikes2Can gradually with the Ca that is precipitated after hydrated cementitious
(OH)2And secondary response occurs for high alkalinity hydrated calcium silicate, generates low alkalinity hydrated calcium silicate, not only makes in Behavior of Hardened Cement Paste in this way
The quantity of aquation gum material increases, and its quality is made to be greatly improved.In the present invention, activity is on the one hand used
Powder and high efficiency water reducing agent improve the energy to failure of matrix to enhance the consistency of matrix while intensity has been greatly enhanced
Power.On the other hand, during crack developing and spike protein gene, fine and close matrix will produce stronger interface friction force, from
And generate the tensile stress of bigger.The superhigh molecular weight polyethylene fibers and super-high strength steel fiber that the present invention uses have Ultra-Drawing
Intensity can guarantee that spike protein gene is not easy to be pulled off in the process.In addition, the hydrophobic character of superhigh molecular weight polyethylene fibers can disappear
Except the chemical bonding between fiber and matrix, the complementary energy of fiber-bridged is significantly increased.If traditional low activity mineral are added to mix
Material, such as flyash are closed, material will be provided with similar stretcher strain ability, but tensile strength will be difficult to more than 10MPa.
