Abstract
The invention discloses a kind of anti-crack concrete, including the component of following weight proportion: 2.5 30 parts of aggregate, cement 20 90 parts, steel fibre or 15 parts of carbon fiber, additive 1 10 parts, POLYPROPYLENE GLYCOL fiber 10 15 parts, phosphorus slag powder 13 parts.Steel fibre and a length of 1 20mm of carbon fiber.Anti-crack concrete cracking resistance of the present invention is strong, and the concrete product made is long for service life.
Description
Technical field
The invention belongs to construction material receive, be specifically related to a kind of anti-crack concrete.
Background technology
Concrete is as existing more than the 100 year history of construction material, and the advantage of concrete is, comprcssive strength is high, appearance of drawing materials
Easily, easy-formation is cheap, can be combined with other materials and make various heavy firmware, but concrete deadly defect is that tension is strong
Spend low, easy to crack, thus reduce the bearing capacity reduction of service life of xoncrete structure, become the hidden danger of various disaster accident.
By adding steel fibre increase cracking resistance in conventional art, but it is easily etched under complex environment, washes away, shadow
Ring the service life of concrete structures.
Summary of the invention
The invention aims to solve defect present in prior art, the invention provides a kind of high-strength cracking resistance
Concrete.
In order to achieve the above object, the invention provides a kind of anti-crack concrete, including the component of following weight proportion: bone
Material 2.5-30 part, cement 20-90 part, steel fibre or carbon fiber 1-5 part, additive 1-10 part, POLYPROPYLENE GLYCOL fiber 10-15 part,
Phosphorus slag powder 1-3 part.Steel fibre and a length of 1-20mm of carbon fiber.
Anti-crack concrete of the present invention, preferred ingredient weight proportion is: aggregate 2.5-30 part, cement 20-90 part, steel fibre or
Carbon fiber 1-5 part, additive 1-10 part, POLYPROPYLENE GLYCOL fiber 10-15 part, economization agent 1-2 part, phosphorus slag powder 1-3 part.
Wherein, economization agent is propylene glycol polyethers, and molecular weight is 2500-3500.
Aggregate includes fine aggregate and coarse aggregate；The mass ratio of fine aggregate and coarse aggregate is 2:1；Fine aggregate is modulus of fineness
II district's medium sand of 2.6-3.0, clay content is less than 3%；Coarse aggregate uses the basaltic broken stone selecting particle diameter to be 10mm～20mm.
What additive used in water reducer, binding agent, activating agent or polyacrylate two or more is mixed with.
Water reducer uses naphthalene series high-efficiency water-reducing agent；Binding agent uses water solublity binding resin；Activating agent uses polyhydric alcohol.
Anti-crack concrete best composition weight proportion of the present invention is: 10 parts of aggregate, cement 70 parts, 2 parts of carbon fiber, naphthalene system height
Effect water reducer 0.5 part, water solublity binding resin 1 part, polyhydric alcohol 0.5 part, polyacrylate 0.5 part, POLYPROPYLENE GLYCOL fiber 13 parts,
Economization agent 1 part, phosphorus slag powder 1.5 parts.
The present invention has the advantage that by active phosphorus slag powder compared to existing technology, can significantly improve and improve
The workability of concrete, mechanical property and endurance quality.Utilize POLYPROPYLENE GLYCOL fiber and economization agent, reduce the contraction of concrete
Amount, improves the anti-crack ability of concrete, and adds it at complicated ring by POLYPROPYLENE GLYCOL fiber part replacement conventional steel fiber
The endurance qualities such as anti-erosion under border, antiscour.By adding additive and aggregate being chosen, increase concrete further
Cracking resistance.
