Abstract
The invention discloses a cement-based repairing material. The cement-based repairing material comprises 0.2-0.8% of organic waterproof agents, 0.5-1.5% of inorganic waterproof agents, 0.1-0.5% of complexing agents, 1-5% of emulsion powder, 1-5% of polypropylene fibers, 1-5% of silica fume, 1-5% of calcium hydroxide, 50-70% of cement, 10-30% of ultrafine quartz sand and 0.5-1.5% of water reducing agents. Through selection of the specific components, the phenomenon of early cracking of mortar is reduced.
Description
Technical field
A kind of the present invention relates to cement technology field, more particularly to cement based material for repairing.
Background technology
Cement concrete pavement is widely used in urban road, highway and airfield runway as a kind of high grade pavement
In, it has the advantages that, and rigidity is big, bearing capacity strong, good stability, durability are high.Specified according to specification JTG D40-2011,
The design period of cement concrete pavement is 20-30, but developing rapidly with national economy, and people are to infrastructure
Also more and more higher is required, the volume of traffic for increasingly increasing proposes requirements at the higher level, heavy duty, the phenomenon of overload to cement concrete pavement
Frequently occur, more accelerate the destruction of cement concrete pavement, badly influence the normal service life of cement concrete pavement.
The repeat function of wheel load when airport concrete road surface is directly born takeoff and landing, slides, its imposed load much surpass
Cross, so being more prone to concrete damage.Runway emergency repair must be quick, and this requires runway maintenance
Engineering time is short, after runway maintenance, can open flight at short notice, safe in guarantee repair quality and takeoff and landing
In the case of, aircraft machine suspending time is reduced to greatest extent.
China is quickly repaired to cement concrete pavement using bituminous material perfusion technique early stage, and concrete way is
The bituminous material of fluidised form is filled in the crack of the solidifying soil surface of mud, after bituminous material solidification, closed concrete crack is played
Effect.But which has many drawbacks, such as concrete is different with the intensity of Colophonium, causes load transfer inconsistent, ageing of asphalt speed
Degree is fast, and service life is short etc..
The content of the invention
It is an object of the invention to propose a kind of cement based material for repairing, it is easy to use to enable to cement based material for repairing, repaiies
Mend rapid.
It is that, up to this purpose, the present invention is employed the following technical solutions：
A kind of cement based material for repairing, including：
Organic waterproof agent 0.2-0.8%
Inorganic water-proof agent 0.5-1.5%
Chelating agent 0.1-0.5%
Latex powder 1-5%
Polypropylene fibre 1-5%
Silicon ash 1-5%
Calcium hydroxide 1-5%,
Cement 50-70%
Superfine quartz sand 10-30%
Water reducer 0.5-1.5%.
Organic waterproof agent of the present invention is fatty acid waterproofing agent.
Inorganic water-proof agent of the present invention is inorganic aluminate water-proof agent.
Superfine quartz sand of the present invention, its particle diameter distribution is between 0.075mm-0.6mm.
The present invention reduces the phenomenon of mortar early-age crack by the selection of above-mentioned specific components.
Specific embodiment
Technical scheme is further illustrated below by specific embodiment.
