A kind of high-performance road rehabilitation king material
Technical field
This patent belongs to building material technical field, particularly relates to a kind of high-performance road rehabilitation king material.
Background technology
After concrete pouring construction, if do not note maintenance, very easily produce cracking, fault-layer-phenomenon.Because concrete is a kind of quasi-brittle material, its tensile strength is low, poor toughness, so crack ubiquity in construction and the bad concrete structure of maintenance, in use often undergo the effect of various travelling load and dead load, the pucker & bloat effect caused because of temperature and humidity change, and the physics of environmental gas and liquid and chemical erosion effect, that concrete produces great Fissure and fracture phenomenon, the havoc traffic capacity of road, some even causes the severe paralysis of passing road.
And at present Application comparison many have fluoaluminate cement fondu system patching material, ultimate compression strength after 2 ~ 6 hours of constructing can reach 15Mpa; Also has the rehabilitating concrete of phosphoric acid salt+peroxide magnesium oxide+retardant matrix material preparation, ultimate compression strength after 1 hour of constructing it is reported and can reach 30Mpa, but this patching material permanent seal cooling need checking, and its price is more than 2 times of silicate cementing material, its construction generally adopts injection, grouting and landfill, the intensity of jet cement generally only has 1 hour about 2Mpa, substantially cannot meet the requirement of repairing rush construction; Although epoxide resin material seam-filling ability is extremely strong, poor with the viscosifying power of tomography, itself ageing-resistant performance is also bad, and repair efficiency is poor, cannot reach the object of rapid rush-repair.
Summary of the invention
The object of the present invention is to provide a kind of high-performance road rehabilitation king material, by the composition of feed change, invent a kind of can repair the concrete road surfaces such as motorway, urban road, urban construction, airport roadway, tunnel fast emergency repair and the type material designed and developed, not only raw material composition is simple, and easy to operate, with low costly have that time of coagulation is fast, cohesiveness good, intensity is high, an advantage such as good and weather resistance is high, anti-skid is good, remarkable reduction noise with normal concrete matching.
For achieving the above object, technical scheme of the present invention is as follows:
A kind of high-performance road rehabilitation king material, its raw materials by weight portion meter, comprises following component:
High-elasticity putty powder originates from Zhejiang, Fujian; The strong aluminosulfate cement of superelevation and low-alkalinity sulphoaluminate cement originate from Shijiazhuang, Hebei, Zhengzhou, henan; Poly carboxylic acid originates from Jiangsu; Retarded adhesive material originates from Shandong.
Preferably, also comprise the low-alkalinity sulphoaluminate cement that weight part is 1-20 part, this material can be complementary with high strength aluminosulfate cement, reduces the alkali content in concrete, improve concrete serviceability.
Preferably, it is No. 3 purity quartzites of 30-55 part and No. 9 purity quartzites of 5-13 part that described quartz sand comprises weight part.
Preferably, described building macromolecular material is any one in anti-crack fiber, tackiness agent, elastic coating, rubber.
A preparation method for high-performance road rehabilitation king material, comprise the steps: to stir in the airtight stirring storehouse of drying according to the parts by weight proportioning of raw material, can obtain road rehabilitation king material, churning time is 20-45 minute.
The beneficial effect of the technical program is: 1) condensation fast: i.e. solidifiable in about 15 minutes, within 1 hour, can be open to traffic, within 1 hour, ultimate compression strength reaches more than 50.0Mpa, and within 1 day, ultimate compression strength just can reach more than 60.0Mpa.
2) cementability is good: folding strength is greater than C30 normal concrete.
3) matching is good: volume stability is high, and contract with dry rate is almost nil, and thermal expansivity reaches normal concrete level.
4) durable height, anti-skid are good: have good freeze-thaw resistance and chemical resistance, wear resistance.
5) can according to old concrete road surface color adjustment product colour, the problem that can aberration avoided as far as possible excessive.
6) use this preparation method to be mixed by raw material, preparation method is simple, and all raw materials are purchase and use, without the need to through secondary processing, and raw-material low price.
