Abstract
The present invention relates to a rapid road patching agent used for engineering salvage operation for airport runways, motorway concrete road surfaces, bridge beams, culverts, tunnels, etc. The present invention is mainly composed of 40 to 65% of fluoaluminate cement clinker, 10 to 30% of industrial residue and 10 to 30% of anhydrite, wherein 0.5 to 8.0% of additive agents which comprise grinding aid, early-strength admixture, retarders and drag reducers can be mixed in the ingredients in a production process. The present invention has the characteristics of high early strength and good abrasion resistance performance, and is suitable for the salvage construction of various kinds of concrete pavement and other concrete facilities.
Description
Technical field
The present invention relates to material of construction, particularly a kind of Road Rapid Repairing Agent that is used for engineering first-aid repair operations such as airfield runway, highway concrete road surface and bridge, culvert, tunnel.
Background technology
Along with development and national economy, road surface with concrete depositing is more and more, damage in various degree can appear in the concrete road surface in the life-time service process, adopting available coagulation soil starting material to make patching material repairs the concrete structure that damages, exist the new-old concrete cohesive strength low, it is long to repair curing time, and endurance quality is poor, the construction requirement height is totally repaired problems such as cost and material cost height.Be open to traffic for unblocking a road and not influencing during pavement patching, need development a kind of have coagulate soon, the Road Rapid Repairing Agent of fast hard, hour intensity height, the performance such as suitable that expands.
Summary of the invention
In order to overcome the deficiencies in the prior art, solve the problem that present material for road repair exists, the purpose of this invention is to provide a kind of have coagulate soon, the material for road repair of fast hard, hour intensity height, the performance such as suitable that expands, i.e. Road Rapid Repairing Agent.
The technical solution adopted for the present invention to solve the technical problems is:
Road Rapid Repairing Agent is characterized in that main component and weight percent are:
Fluoaluminate cement clinker 40～65%;
Industrial residue 10～30%;
Anhydrite 10～30%.
Mix 0.5～8.0% admixture.
Described admixture is grinding aid, hardening accelerator, retardant and flow improver, and its weight percent is: grinding aid 0.5～2.0%, hardening accelerator 0.5～2.0%, retardant 0.01～1.0%, flow improver 0.5～2.0%.
Described admixture is respectively: grinding aid is a charcoal, and hardening accelerator is vitriol, and retardant is a mineral acid, and flow improver is the keto-aldehyde condenses.
It is can produce sufficiently high hour intensity, wear resisting property and good construction performance in order to guarantee when the mending concrete road surface that the present invention mixes admixture in process of production.The Road Rapid Repairing Agent intensity index of being produced is: 4 hours ultimate compression strength 〉=25.0MPa, and 1 day ultimate compression strength 〉=45.0Mpa, 28 days ultimate compression strength 〉=55.0Mpa, wear resistance represents with abrasion loss, must not be greater than 3.0kg/m

Be the present invention and the comparison of the road cement physicals of use at present below:
| Kind | Ultimate compression strength (MPa) | Folding strength (MPa) | Wear resistance (kg/m 2) (in abrasion loss) | ||||
| 4 hours | 1 day | 28 days | 4 hours | 1 day | 28 days | ||
| Road Rapid Repairing Agent | ≥25.0 | ≥45.0 | ≥55.0 | ≥4.5 | ≥6.0 | ≥7.2 | ≤3.0 |
| Quick hardening Portland cement 42.5 | / | ≥19.0 | ≥62.5 | / | ≥4.5 | ≥8.0 | / |
| Road silicate cement 42.5 | / | / | ≥42.5 | / | / | ≥7.0 | / |
As can be seen, the present invention has the early strength height from comparative data, the characteristics that wear resisting property is good.Be applicable to the first-aid repair construction of various concrete road surfaces such as airfield runway, highway, bridge, culvert, tunnel and concrete facility.
Embodiment
Provide specific embodiments of the invention below:
Embodiment 1:
Fluoaluminate cement clinker 55%, industrial residue 23%, anhydrite 22%.
Mix admixture outward: charcoal (grinding aid) 2.0%, sodium sulfate (hardening accelerator) 1.5%, tartrate (retardant) 0.1%, JZ-1 (flow improver) 2.0%.
Road Rapid Repairing Agent concrete strength index by this component production: 4 hours ultimate compression strength is 38.2MPa, and 1 day ultimate compression strength is 46.1Mpa, and ultimate compression strength was 56.0Mpa in 28 days, and wear resistance is expressed as 2.5kg/m with abrasion loss
2
Embodiment 2:
Fluoaluminate cement clinker 60%, industrial residue 20%, anhydrite 20%.
Mix admixture outward: charcoal (grinding aid) 2.0%, sodium sulfate (hardening accelerator) 1.0%, tartrate (retardant) 0.08%, JZ-1 (flow improver) 2.0%.
Road Rapid Repairing Agent concrete strength index by this component production: 4 hours ultimate compression strength is 34.3MPa, and 1 day ultimate compression strength is 46.1Mpa, and ultimate compression strength was 55.6Mpa in 28 days, and wear resistance is expressed as 2.3kg/m with abrasion loss
