Abstract
The invention aims to prepare a special material capable of being used for rapid rush-repair of roads. The material is formed by mixing quick-hardening sulphoaluminate cement, double quick cement, an expanding agent, redispersible latex powder, water-washing river sand, an early strength agent, an accelerating agent, an anti-freezing agent, anti-crack fibers, a defoaming agent and the like. The material comprises, in weight percentage, 35-50% of the quick-hardening sulphoaluminate cement, 3-8% of reinforced components, 40-55% of the water-washing river sand, 2-5% of the expanding agent, 3-6% of the redispersible latex powder, 2-5% of a water reducing agent, 0.1-0.5% of the early strength agent, 0.1-0.3% of the anti-freezing agent, 0.1-0.3% of a retarder, 0.1-0.6% of the anti-freezing agent, 0.02-0.05% of polypropylene fibers and 0.1-0.5% of the defoaming agent. The material has the advantages of good fluidity, high hourly strength, high cementing bond, cracking resistance and the like, and is applicable to rapid rush repair of the municipal roads at low or normal temperature.
Description
Technical field:
The present invention relates to a kind of material that can be used for the quick repairing of road and preparation method thereof.
Background technology:
China has experienced fast-developing 30 years, and in this period, China has built a large amount of highway bridges, and the while is along with the continuous expansion of scale of urbanization, the domestic a collection of megapolis such as Beijing, Shanghai, Guangzhou, Shenzhen that formed.Because vehicle possess amount increases considerably, the traffic congestion in city has become the persistent ailment of urban development.And use for many years motorway, urban road destruction in various degree also to occur; If according to traditional pavement patching mode; Will certainly produce great influence to the traffic in city, the rapid restoring material of therefore developing a kind of initial stage good fluidity, hour intensity height (generally 2h can be open to traffic after repairing) operable time length is imperative.Aspect repairing; At present domestic also formation improved and sophisticated system; Most repairing method is in cement and adds that thermoplasticity or thermosetting resin realize; Though this repairing method can guarantee the adhesive property between patching material and the concrete substrate, but often the engineering time is short, cost is expensive, is not suitable for the extensive repairing of urban road.Chinese patent CN 101096303 has reported and has a kind ofly built the road, the preparation method of rapid restoring material for building; This method effectively reduces the road cost of repairing fast; Has certain popularization value; But but this material still exists the defective of engineering time short (basically in the 15min), 2 hours intensity (basically between 15-17MPa) on the low side, is difficult to large-scale application in municipal traffic.
Summary of the invention:
The present invention is intended to prepare a kind of operable time greater than 30min; 2h ultimate compression strength is greater than 30MPa and construction back and high, the indehiscent extraordinary restoring material of basic unit's cohesive force; This material especially still has good gain in strength under the low-temperature construction environment; Basically can satisfy at normal construction more than 5 ℃, therefore increase the scope of application of this product greatly.
A kind of road rapid restoring material that is used for construction under normal temperature and the low temperature environment that the present invention relates to is formulated by following compositions in weight percentage: rapid hardening cement: 20～60%, and enhancement component: 2～10%; Washing river sand: 30～65%; Swelling agent: 1～10%, redispersable latex powder: 1～10%, water reducer: 1～8%; Hardening accelerator: 0.05～0.8%, accelerating chemicals: 0.05～0.5; Retardant: 0.05～0.5%, frostproofer: 0.05～1%, polypropylene fibre 0.01～0.06%, skimmer: 0.05～1%.Each component can be preferably: rapid hardening cement 35～50%, and enhancement component: 3～8%, washing river sand: 40～55%; Swelling agent: 2～5%, redispersable latex powder: 3～6%, water reducer: 2～5%; Hardening accelerator: 0.1～0.5%, accelerating chemicals: 0.1～0.3, retardant: 0.1～0.3%; Frostproofer: 0.1～0.6%, polypropylene fibre 0.02～0.05%, skimmer: 0.1～0.5%.
In the above-mentioned road rapid restoring material, said rapid hardening cement is an aluminosulfate cement; Said enhancement component is a double-quick cement; Said washing river sand is the river sand of 20 orders～100 order continuous gradings for the particle diameter after washing; Said swelling agent is an aluminate-aluminosilicate expanding agent; Said redispersable latex powder is Injecatable EVA Copolymer or vinylformic acid-cinnamic copolymer, and said water reducer is early-strength type polycarboxylate water-reducer or naphthalene water reducer; Said retardant is Sunmorl N 60S, Trisodium Citrate, tartrate or any two kinds composite; Said frostproofer is Sodium Nitrite, calcium nitrite or the two composite by a certain percentage forming; Said hardening accelerator is one or more in sodium sulfate, calcium formiate, the Quilonum Retard.Said skimmer is the organosilicon powder skimmer.Said polypropylene fibre is the 5mm fiber.Said accelerating chemicals is an aluminum oxide clinker class accelerating chemicals.
The present invention is mixed through Agravicmixer by rapid hardening cement, silica sand, swelling agent and other various auxiliary agents according to a certain percentage.All raw material is commercially available material of construction or industrial auxiliary agent.
The invention has the advantages that: 1. adopt the organic compound of accelerating component and antifreezing component, increased substantially the serviceability of product under low temperature or subzero temperature condition, guarantee that product can reach more than the 20MPa in 2 hours ultimate compression strength below 5 ℃.2. grating is reasonable, and microdilatancy is obvious; Because formula system has carried out strict screening to consumption, the grating of aluminosulfate cement, silica sand, thereby has greatly improved the volume stability of product, has guaranteed the not retraction of product later strength.3. the use of double-quick cement not only can improve the early strength of product, makes product realize high workability and high-intensity coordinated development in 2 hours half a hour simultaneously.4. this product has superior adhesive property, can obviously improve the cohesive strength of repairing material and concrete substrate.
Embodiment:
Below with embodiment the present invention is described further, but said embodiment only is used to the present invention is described and does not limit the present invention.
