Bridge expansion joint reinforcement and maintenance structure repair quickly with high polymer material

Bridge expansion joint reinforcement and maintenance structure repair quickly with high polymer material of bridge expansion joint repair and replacement dedicated mortar ( Also called quick-setting cement, quick-setting mortar, mortar or bridge expansion joint) , the United States is based on cement combined with seam an agent, high strength materials ( Quartz sand) South to polymer powder as the main aggregates, rate, high efficiency water reducing the seam an agent, early strength seam an agent expansion seam an agent, made from materials such as high analysis type super early strength of concrete structure repair material. This product is their sex good, rapid hardening, early strength, high strength, no shrinkage, micro expansion month long; Non-toxic harmless, not aging, on the water quality and the surrounding environment pollution-free, good tightness, the rust resistance etc. JG/T336 - a, performance indicators 201 1 « Concrete structure repair with polymer cement sand & # 187; 2 h24h28 days compressive strength of compressive strength of JZ (compressive strength Bridge expansion joint) 30 mpa or greater acuity 20 mpa or greater 50 mpa jz note 1 about 30 min can adjust the water can be used after being mixed yao note 1 cubic need dry 2200 kg, application range, bridge expansion joints in pieces rapid repair of cement concrete pavement broken slab rapid repair A three, construction technology and technological process. Base leaching; Smell: on, 2 - YaoZhu before 3 hours will base water wet holes and removing the MingShui fully; When winter construction, should be in, before YaoZhu base in not more than 65 ℃ warm water to fully wet and remove MingShui. B。 Interface treatment: evenly on the surface of the base, more brush a layer of polymer interface beautiful seam an agent. C。 Shuttering: for repair is located in the middle of the road cement concrete pavement plate, available around the edge as a template; For a road to repair is located in the edge of the cement concrete pavement plate, the third side available around the edge as a template, should support wooden or steel mould of edge, and take the leakproof slurry measures. For reinforced concrete structure, serious damage should support to finalize the design template and adopt measures to prevent packing. D。 Mix: according to the number of in situ and casting speed, will be put into force pattern repairing artificial mortar mixer, the dry mix after 10 s, according to the water content after weighing of the product, and two water 1 and a half and: first add 2/3 water, mixing 30 s; A second and a third water, mixing the 150 s. After mixing, repair materials should be let stand for 2 - 3 min, after waiting for air bubble disappear again for casting. When winter construction, should use no more than 65 ° C in warm water for mixing, pouring temperature should be in more than 10 ° C. E. Water the building: using casting container to slow, uniform, YaoZhu close-grained, pouring should avoid empty drum phenomenon. East after casting, the repair material screeding J page. 1 and a half of repair material, every time, starting from the system with until the end of casting, time more than 30 min. Timeout or did not meet the requirements of pouring liquid repair material, may not continue to use. F。 Health: with plastic cover at the top of the repair material, then use chapter bags completely cover on the plastic article keep wet, countries. Under normal temperature, 3 ~ 4 h after the end of preserve one's health, or according to the request of structure strength and the reserved specimen strength test results to decide whether to end of preserve one's health. Winter heat preservation measures should be adopted, curing period may be extended appropriately. 3 pieces, matters needing attention patching material mixing water appropriate is used to drinking water. JZ type should be changed according to product requirements, way choice preferential water control slump and collapsing primary high degree. Repair of the bridge structure used in the template, xuan adopt new template, after ripping and beautiful appearance. After construction, machine wash immediately with water dry) And arrange another time to use. In the process of material transportation, rainproof measures should be taken. Material should be placed in a cool, dry place, storage, shelf life 6 months, beyond the guarantee period the re-inspection qualified rear can use. Four, packaging, storage, using composite brown paper bag packaging, net weight 50 kg/bag, shelf life 6 months; Pieces shall be stored in dry and ventilated indoor, sealed packet, note moistureproof, prevent frostbite.
