Description
Technical field
The present invention relates to a kind of pavement maintenance material, especially relate to the quick servicing materials in concrete road surface of a kind of motorway and urban road.
Technical background
The motorway mileage open to traffic constantly increases just with surprising rapidity, and As time goes on, damage in various degree can appear in highway pavement and bridge deck pavement, causes pavement quality to descend, and this will directly influence Vehicle Speed and safety.Giving full play to the service efficiency of motorway, prolong working life, improve the quality and the speed of highway maintenance maintenance, is a new problem that faces in the Development of Freeway process.
At present, concrete road surface servicing materials commonly used mainly contains three types: the first kind, with the concrete material of ordinary Portland cement and aggregate preparation; Its advantage is that cost is low; Consistent with the old concrete performance, but maintenance concrete and old concrete imperfect bonding, curing time is longer; Second type, organic polymer material, like epoxy resin, polyamine fat etc., its advantage is that cohesiveness is good, and sclerosis is fast, and impermeability and corrosion resistance are good, but this material cost is high, easy ageing is bigger with the expansion coefficient difference of old concrete; The 3rd type, special material mainly contains high-aluminium cement series, water glass series and phosphate cement series etc., and its advantage is a fast solidifying, and early strength is high, and is approaching with the old concrete wood property, but the high-alumina cement later strength is unstable, is easy to generate strength retraction.
Summary of the invention
The object of the present invention is to provide a kind of time of coagulation suitable, setting rate is fast, and early strength is high; Bonding strength is high; With concrete better consistency is arranged, not retraction of later strength, good endurance; Water impermeability is good, the quick servicing materials of the motorway that the convergent-divergent coefficient is little and the concrete road surface of urban road.
The objective of the invention is to realize through following technical scheme:
The present invention's concrete road surface servicing materials mainly is made up of ash material and aggregate, the weight proportion=20-40 of ash material and aggregate: 80-60; The weight proportion of each composition material of ash material is: low-alkalinity sulphoaluminate cement 40%-100% (preferred 70%-90%); Gypsum base composite gelled material 0-40% (preferred 10%-30%); Accelerating chemicals 0-2.0 ‰ (preferred 0.5-1.5 ‰), retardant 0-2.0 ‰ (preferred 0.5-1.5 ‰).
Said gypsum base composite gelled material is mainly by fluorgypsum, active blending material, alkali-activator; Setting accelerator is formed; The weight proportion of each composition material is: fluorgypsum: active blending material: alkali-activator: setting accelerator=55-70: 15-40: 5-15: 1-3, each component more preferably proportioning is 70: 39: 9: 2.When if above-mentioned active blending material basicity (the pH value is less than 9.0) is not enough, also can add the lime of 1wt%-3wt%.
Said active admixture is one or more the mixture that is selected from levigate blast-furnace slag, levigate water-granulated slag, fine-ground fly-ash, levigate slag, the levigate red stone slag, granularity >=100 orders.
