Description
Technical field
The present invention relates to a kind of road injecting paste material processing and manufacturing field, and in particular to it is a kind of for roadbase reinforce
Geopolymer dual-liquid slip-casting material and preparation method thereof.
Background technology
Occur coming to nothing currently for the diseases such as old asphalt pavement is cracking, depression, pit and cement concrete pavement
During disease, the pavement shallow injecting paste material for generally adopting has：Cement mortar, organic polymer class.Cement class injecting paste material mobility,
Permeance property is poor, it is difficult to the tiny hole of injecting structure layer, its poor durability, easily occurs softening after slip casting and secondary purt is starched；
High polymer high polymer slip casting early stage can only interstitital texture layer cavity etc., water sealing effect is more obvious, cannot but consolidate interlayer
Loose material, hard-foam polyurethane creep after 1 year, creep with it is aging after, will occur interlayer again and come to nothing, and required apply
Work technique and technical requirements are high, are not suitable for the road surface that heavy damage occurs.
In view of the grout material of roadbase slip casting mainly fills the trickle space of pavement structure interlayer, bonding and reinforcement pine
The interlayer materials dissipate, come to nothing, therefore be to form higher intensity within a short period of time first after slip casting, so as to reach significantly
Reinforcing effect, and the bearing capacity on road surface is improved, this requires that injecting paste material has following several performances：
1）Slurry fluidity is good, and permeability is high, serosity is preferably permeated in a low voltage state, and the property noted is strong, pumpability
Can penetrate in tiny crack or hole well.And the Behavior of Hardened Cement Paste of uniform, high-strength, good adhesion is formed after consolidation, eliminate
Small spaces in structure sheaf, reach the purpose for administering pavement distress disease.
2）The selection of alkali-activator, will can activate the inert material of soil or interlayer mud, geopolymer injecting paste material
Make the bonding such as mud of loose structure sheaf, structure sheaf form a Seed harvest, that is, form the elastic stratiform being bonded as one
Structural system.
3）Seed harvest early strength is high, with certain resistance to compression, rupture strength, impervious good, antiscour and resistance to ag(e)ing
Can be good.Construction of the highway must assure that section is unimpeded, thus sets out and understands that the time of construction closing and section are more short better, therefore
It is required that its early strength is high, the intensity in general 3d will reach more than 5MPa.
4）Injecting paste material will have good bleeding and contractility.Ungauged regions but microdilatancy when grout curing, it is hard to improve
Slurrying body and cement concrete slab and the bonding of basic unit.
5）Setting time can be arbitrarily adjusted in the range of a few number of seconds hours, and accurately can be controlled, with fast hard solidification, end
The characteristics of solidifying time is short.
6）Good stability, at normal temperatures and pressures long period storage do not change its fundamental property.Temperature humidity is not received in storage
The impact of change, material environment friendly easy construction cleaning, safety non-toxic.
The defect that existing road injecting paste material is present is such as：Cement injection material fluidity is big, and rupture strength is low, and bleeding is tight
Weight, high polymer grouting material can produce creep under load action, so as to produce it is new come to nothing, tired service life is shorter,
The needs of existing engineering cannot be met.
