Description
Technical field
The present invention relates to a kind of road surface/bridge deck concrete rapid repair material and uses thereof, belong to material of construction.
Background technology
Along with Chinese national economy high speed development, various highway, bridge, municipal engineering construction are swift and violent.Wherein, cement concrete pavement proportion amplification is remarkable.At the repeated action of load and physical environment as freeze-thaw cycle, salt freeze, under the continuous impact of the factor such as carbonization, and under the comprehensive action of the factors such as design, construction, maintenance, cement concrete road surface during use, inevitably produce various damage, as cracking, hole groove, be full of cracks etc., have influence on traffic passage rate and quality, produce traffic problems.For reducing traffic problems as far as possible, repairing reparation must be carried out to the face, road damaged in time.
There is the serious existing technical scheme of disease such as hole, hole, fragmentation, crack normally in road surface/bridge deck concrete: raw sheet fragmentation--excavates--deposit concrete again--maintenance--open to traffic.
And existing scheme Problems existing has:
1. former scheme: broken, excavate and need a large amount of machinery and artificial, and rubbish and concrete transportation cost high, producing a large amount of building wastes affects environment, and overall cost is high.
2. the concrete again poured into a mould inevitably and between the concrete retained can produce desciccation crack, greatly reduces the quality and work-ing life of newly changing plate, general work-ing life 2-3.
3. the concrete pouring cycle of again pouring into a mould is long, general needs 14 to 28 days, also at least 7 days can open to traffic even if add hardening accelerator; Have impact on and have a good transport and communication network, easily cause traffic accident to occur.
Summary of the invention
The invention provides a kind of road surface/bridge deck concrete rapid repair material and uses thereof, solve the problems such as existing repair material repairs difficulty, curing time is long, work-ing life is short.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
A kind of road surface/bridge deck concrete rapid repair material, according to parts by weight, comprise aluminosulfate cement 20-30 part, 52.5 ordinary Portland cement 8-10 parts, ethene and vinyl acetate polymer rubber powder 5-10 part, Tai-Ace S 150 0.5-1.5 part, water glass 1-2 divides, organosilicon 0.1-1, gypsum 1-2 part, slag 2-3 part, silicon powder 0.1-0.5 part, HPCA high-performance cement expansive agent 0.5-1 part, flyash 3-5 part, washing baked sand 20-30 part, silicon carbide 25-30 part, conjugated fibre 3-5 part, polycarboxylate water-reducer 1-3 part, boric acid 0.1-0.5 part, Sunmorl N 60S 0.1-0.3 part and Quilonum Retard 0.2-1 part.
Further, a preferred embodiment of the present invention is: described conjugated fibre is one or the mixture of steel fiber and PP fiber.
Further, a preferred embodiment of the present invention is: described conjugated fibre is the mixture of steel fiber and PP fiber, steel fiber: the weight ratio of PP fiber is 1-2:2-3.
Further, a preferred embodiment of the present invention is: the length-to-diameter ratio 45-65 of described steel fiber, diameter of section 0.40-0.65mm.
Present invention provides the method for a kind of road surface/bridge deck concrete Rapid-Repair, comprise the following steps:
The first step, by the concrete joint-cutting of breakage, to cut, then the concrete waste material cut is cleaned out;
Second step, by repair material of the present invention, according to water: the ratio of repair material weight ratio 14-14.5:100 mixes, cast;
Open to traffic after 3rd step, last road closed maintenance 1-2h.
Ethene in the present invention and vinyl acetate polymer rubber powder are vinyl acetate and ethylene copolymer rubber powder.
Beneficial effect of the present invention:
Repair material of the present invention adopts aluminosulfate cement, 52.5 ordinary Portland cements, Tai-Ace S 150, ethene and vinyl acetate polymer rubber powder, gypsum, slag, silicon powder, swelling agent, flyash to be inorganic and organic composite type gelling matrix material, can realize having very high resistance to compression, anti-folding, cohesive strength to concrete; Washing baked sand, silicon carbide are aggregates; The conjugated fibres such as steel fiber+PP fiber are composite cracking strongtheners; Polycarboxylate water-reducer can reduce material amount of water, increases degree of mobilization, reduces the contraction of volume, increase concrete intensity, the adjustment operation setting times such as boric acid, Sunmorl N 60S, Quilonum Retard; Inorganic coagulation material, polymer glue powder, water glass acting in conjunction have excellent gumminess, and concrete road surface and repair material can be made to combine closely; HPCA high-performance cement expansive agent and Tai-Ace S 150 pulvis solve the conventional difficulties of concrete setting volumetric shrinkage, make adhesive surface can not produce new desciccation crack; Adding of organosilicon pulvis makes patching material waterproof freeze proof, and the combination of ethene and vinyl acetate polymer rubber powder polymer glue powder and aluminosulfate cement significantly can reduce the backfin ratio of sand-cement slurry, improves mortar snappiness.
Repair material early strength of the present invention is high, and only needing after having repaired 1--2 hour can quick open to traffic.Solve tradition mend technique close traffic time length by replacing a damaged part and cause a traffic congestion difficult problem, reduce the generation of traffic accident.
Repair material of the present invention solve a few great tradition repair in a difficult problem: 1. high the and good toughness of intensity, 2. resistance to compression, folding strength are more than 2--3 times of original pavement concrete, 3. resistance to impact shock is more than 5--10 times of normal concrete, 4. resistance to impact shock is 5-10 times of normal concrete, makes patched concrete slab have better intensity; Vehicle can better be stood roll, shake, to impact and not broken.
Repair material of the present invention can be firm with periphery concrete binding, solidifies rear volume and do not shrink and do not have desciccation crack, solve traditional road patching material and solidify the industry difficult problem that rear volumetric shrinkage produces regeneration crack.
The matching of repair material of the present invention is good, very little with original concrete aberration, and expand with heat and contract with cold also consistent with former concrete, repairing quality and work-ing life get better protection.
Machinery needed for method for repairing and mending Rapid-Repair road and bridge crack of the present invention, artificial, transportation cost is low; Remain original basis segment plate preferably, only broken and zones of extensibility need be cut, the building waste quantity of generation is few, accomplishes more efficient, more economical, more energy-conservation, more environmental protection with former project plan comparison! Save maintaining cost.
