Abstract
The invention discloses a quick patching material for a cement concrete pavement, which is prepared from the following components in parts by weight: 500-700 parts of slag powder, 300-500 parts of soluble glass, 120-180 parts of sodium fluosilicate, 50-100 parts of desulfurized gypsum, 0.1-0.3 part of rosin soap, 400-600 parts of recycled concrete fine aggregate and 600-800 parts of recycled concrete coarse aggregate. The quick patching material for the cement concrete pavement of the invention has the advantages of high early strength, high speed of patching the damaged parts of the cement concrete pavement, full utilization of the desulfurized gypsum, the slag powder and other industrial wastes and damaged cement concrete pavement slabs, reduction of the production cost, and little influence on peripheral traffic and the environment in the process of patching the pavement.
Description
Technical field
The invention belongs to concrete field, be specifically related to a kind of quick patching material for cement concrete pavement.
Background technology
Along with urban transportation facility construction process is accelerated, various concrete structures are more and more, and particularly the mileage of cement concrete pavement is more and more longer.But along with the rapid increase of urban traffic amount, many concrete road surfaces were damaged prematurely, therefore, had had a strong impact on the service efficiency of traffic facilities, for traffic trip also brings great inconvenience in recent years.
At present, adopt common concrete patching material that the road surface of breakage is repaired, generally want maintenance just can be open to traffic in many days, can have a strong impact on peripheral traffic like this; On the other hand, available coagulation soil surface patching material adopts the higher relatively Industrial materials of price as raw material more, and production cost is high; Therefore, be badly in need of providing a kind of and can improve Cement Concrete Pavement Reconstruction material early strength, ahead of time open to traffic and the low quick patching material for cement concrete pavement of production cost.
Summary of the invention
The technical problem that the present invention will solve is the above-mentioned deficiency to prior art; Provide a kind of early strength high; The damaged repairing speed of cement concrete pavement is fast; Can make full use of trade waste and damaged Cement Concrete Pavement Slab such as desulfurated plaster, slag powders, reduce production costs, and in the pavement patching process quick patching material for cement concrete pavement little to the influence degree of peripheral traffic and environment.
In order to solve the problems of the technologies described above; Technical scheme of the present invention is: a kind of make full use of slag powders, desulfurated plaster as gelling material and discarded concrete as the quick patching material for cement concrete pavement that gathers materials, this patching material is prepared from each component of following weight part: slag powders 500～700 weight parts, water glass 300～500 weight parts, Sodium Silicofluoride 98min 120～180 weight parts, desulfurated plaster 50～100 weight parts, rosined soap 0.1～0.3 weight part, regeneration concrete fine aggregate 400～600 weight parts, regeneration concrete coarse aggregate 600～800 weight parts.
Preferred as further; Cement Concrete Pavement Reconstruction material of the present invention, this patching material is prepared from each component of following weight part: slag powders 550～650 weight parts, water glass 350～450 weight parts, Sodium Silicofluoride 98min 140～160 weight parts, desulfurated plaster 70～90 weight parts, rosined soap 0.15～0.25 weight part, regeneration concrete fine aggregate 450～550 weight parts, regeneration concrete coarse aggregate 650～750 weight parts.
As most preferably; Cement Concrete Pavement Reconstruction material of the present invention, this patching material is prepared from each component of following weight part: slag powders 600 weight parts, water glass 400 weight parts, Sodium Silicofluoride 98min 150 weight parts, desulfurated plaster 80 weight parts, rosined soap 0.2 weight part, regeneration concrete fine aggregate 500 weight parts, regeneration concrete coarse aggregate 700 weight parts.
The specific surface area of above-mentioned slag powders is not less than 400m
2/ kg.
Above-mentioned water glass is that water glass (being commonly called as: water glass or bubble flower alkali), potassium silicate (are commonly called as: a kind of potash water glass).
Above-mentioned water glass, the modulus of potassium silicate are all greater than 2.4.
Above-mentioned water glass, the degree Beaume of potassium silicate are all greater than 50 ° of B é.
Above-mentioned regeneration concrete fine aggregate particle diameter is 0.63～5mm.
Above-mentioned regeneration concrete coarse aggregate grain size 5～25mm, this regeneration concrete crushing coarse aggregates value is less than 25%.
Above-mentioned regeneration concrete fine aggregate and regeneration concrete coarse aggregate all adopt existing routine techniques preparation and get.
Advantage of the present invention and beneficial effect:
1. quick patching material for cement concrete pavement of the present invention has the early strength height, and the damaged pavement patching speed of cement concrete is fast, just can realize that the road is clear in the short period of time, for good traffic is provided convenience advantages such as favorable working performance; And quick patching material for cement concrete pavement of the present invention mainly utilizes gathering materials as component after trade wastes such as desulfurated plaster, slag powders and the damaged concrete flag fragmentation; This is one and utilizes solid waste, improves the effective way of environmental pollution and raising road passage capability.
2. the present invention adopts slag powders; Desulfurated plaster and damaged concrete flag are prepared quick patching material for cement concrete pavement as starting material, have made full use of waste material, do not use the higher relatively cement of price in the conventional formulation as raw material; Therefore, reduced production cost.
