Concrete repair materials and method.
Background technique
The traffic infrastructures such as China's highway are established in the nineties in last century, with the development of the social economy, road
Construction is even more to make rapid progress, currently, China's highway mileage has broken through 130,000 kilometers.But constantly along with the volume of traffic
Increase, overload, environmental load effect, reinforcement corrosion, freeze thawing damage, fatigue effect, corrosion effect and material aging etc. it is natural and
The influence of artificial unfavorable factor, the engineering structures such as highway and bridge are inevitably generated bearing capacity decline, drag
The problems such as decaying, damage accumulation, structure durability reduce, seriously affects Vehicle Speed and safety, in some instances it may even be possible to lead to calamity
Difficult sexual behavior thus occur.Therefore, the service efficiency of highway how is given full play to, service life is extended, improves highway
The quality and speed of maintenance are the key subjects that must be faced in traffic control department and Expressway Development process.
Currently, the common used material that China's expressway surface is quickly repaired mainly has three classes: 1) using ordinary portland cement and bone
Expect the concrete material of configuration, its advantage is that it is at low cost consistent with old concrete performance, but this traditional maintenance method late maintaining
Time is too long, and bad adhesion, shrinks greatly, causes repairing pavement durability poor, and damaged place generally requires to repair repeatedly, because
This is difficult to meet actual demand；2) special cement class mending mortar, advantage are that condensation is fast, and early strength is high, but through extraordinary water
The problems such as cement concrete pavement of mud repairing will appear later strength retraction phenomenon and undesirable linking new and old concrete；
3) fiber concrete, ductility and deformability are strong, but it is complicated to construct, and the long period is needed to can be only achieved pavement usage institute
The intensity index needed；4) it polymerize species concrete, such patching material must rationally control additive amount, can just develop high-quality reality
Fast repairing material, it is big that material configures difficulty, it is difficult to meet the site operation requirement of highway Rapid-Repair.Therefore,
It is short to develop a kind of setting time, high mechanical strength, shelf life long material for quickly repairing and convenient site operation technology,
To reach the requirement of expressway surface Rapid-Repair, become a strategic point problem to be solved.

Long property and service life are greatly enhanced compared with normal concrete, and on-site construction operations are simple, fully meet expressway surface and quickly repair
The multiple requirement to quality and time.Expressway surface fast repairing method on-site construction operations of the invention are simple, concreting
The condensation of materials time is short, and high mechanical strength and intensity rise fast, and caking property, durability and service life are more equal than normal concrete
It improves a lot, curing time is short, is open to traffic fast, is suitably applied the various works such as expressway surface, bridge pavement and airport pavement
In journey repairing.
Detailed description of the invention
Fig. 1 is the step process of embodiment high speed road surface fast repairing method.
Specific embodiment
Below in conjunction with the accompanying drawings and embodiment the invention will be further described.
Embodiment 1
Referring to attached drawing 1, when it is implemented, carry out expressway surface quickly repair the following steps are included:
Step 1: Concrete Repairing Materials mix-design designs before construction starts according to climate temperature and field conditions
The optimum mix proportion of concrete material out, and verification experimental verification is carried out, the indexs such as test setting time, mechanical strength, mobility are matched
Composition and division in a proportion is finely adjusted according to the actual situation.The concrete material of use matches are as follows:
| Water | Cement | Quartz sand | Stone | Silicon ash | Water-reducing agent | Retarder | Fiber | |
| 1 concrete repair materials of embodiment | 16 parts | 46 parts | 75 parts | 112 parts | 4 parts | 1 part | 0.02 part | 0.4 part |
Step 2: cutting being carried out to damaged road surface and is cut, the crushed stone and dust inside pit slot are cleaned up, is laid with as needed new
Reinforced mesh, little water is then sprinkled inside pit slot, and uniformly spray interfacial agents.
Step 3: the optimum mix proportion verified according to actual tests prepares concreting material, wherein the ratio of mud,
Retarder and fiber doping amount should be finely adjusted again according to on-site actual situations and the mobility of concrete.
Prepare concrete material stirring means when concreting material are as follows:
A) cement, quartz sand, stone and silicon ash are put into 2 ~ 3 minutes by agitated kettle dry mixing according to optimal proportion；
B) fiber is added while stirring, fiber, which is added, slowly fiber when stirring to be avoided to generate clustering phenomena；
C) water is added slowly to inside agitated kettle (water-reducing agent and retarder dissolve inside water in advance), is stirred for after adding water
1 ~ 2 minute；
D) it discharges, pour.
Step 4: concreting material being poured into pit slot, is vibrated in time, vibrating spear selects plug-in type, vibrates and wants
Uniformly and sufficiently, because joined fiber in concrete, cause mobility poorer than normal concrete, and in order to pursue intensity,
The concrete material ratio of mud of the invention is smaller, therefore process of vibrating is most important, flat with touching knife for concrete and touching after vibrating.
Step 5: according to environment temperature, geotextiles can be spread within general 1 hour or so after concreting and sprinkled water and supported
Shield can be open to traffic after 4 ~ 6 hours.
Embodiment 2
Step 1: Concrete Repairing Materials mix-design designs before construction starts according to climate temperature and field conditions
The optimum mix proportion of concrete material out, and verification experimental verification is carried out, the indexs such as test setting time, mechanical strength, mobility are matched
Composition and division in a proportion is finely adjusted according to the actual situation.The concrete material of use matches are as follows:
| Water | Cement | Quartz sand | Stone | Silicon ash | Water-reducing agent | Retarder | Fiber | |
| 2 concrete repair materials of embodiment | 18 parts | 46 parts | 75 parts | 101 parts | 4 parts | 0.8 part | 0.015 part | 0.3 part |
Step 2-5 is the same as embodiment 1.
Technical effect of the invention is made below with reference to two kinds of specific concrete repair materials in embodiment further
Illustrate:
According to the concrete repair materials component match ratio and production method preparation of the invention in embodiment 1 and embodiment 2
Concrete repairing material, and vibration compacting make reference block, test initial set, final setting time, 8 hours, 1 day, resistance to compression in 3 days
And flexural strength, as a result as shown in table 1, table 2:
1 concrete material setting time of table and mobility
| Presetting period | Final setting time | Mobility | |
| Concrete repair materials one | 25min | 45min | Preferably |
| Concrete repair materials two | 35min | 1h | Very well |
2 concrete material mechanical property of table
| 8h resistance to compression (MPa) | Resistance to compression (MPa) in 1 day | Resistance to compression (MPa) in 3 days | The anti-folding (MPa) of 8h | 1 day anti-folding (MPa) | 3 days anti-foldings (MPa) | |
| Concrete repair materials one | 42.4 | 58.5 | 55.6 | 4.6 | 5.9 | 6.5 |
| Concrete repair materials two | 43.5 | 49.8 | 59.7 | 4.4 | 5.6 | 6.4 |
It can be seen that: initial set, final setting time and the mobility of concrete repair materials of the invention meet the requirement of site operation, and
8 hours compression strength of concrete repair materials can reach 40MPa or more, fully meet the demand that is open to traffic.
The above are preferred embodiments of the present invention, all any changes made according to the technical solution of the present invention, and generated function is made
When with range without departing from technical solution of the present invention, all belong to the scope of protection of the present invention.
