Post-earthquake reinforcement and repair special considerations - grouting material Grouting material models

Reinforcement grouting reinforcement grouting reinforcement grouting material manufacturer price post-disaster restoration grouting material is composed of high strength cementitious materials, a variety of beauty and seam an agent compound and selected aggregate made from after the special craft, with large fluidity, no shrinkage, early strength and high strength and so on the characteristic of special high strength grouting material repair after the explosion.   By the cement base gelling material and mineral admixture, high performance and beautiful seam an agent, such as the factory production. Below the water mix into the bolt hole and orbit, to achieve uniform load transferring bear the forces of the upper, in the port, wharf, can improve the durability of high speed railway, shorten the construction period, disaster relief, reduce pollution.   Use scope: the & # 8195; 1, port, wharf crane rail slot of grouting. Rail clips, base plate, bolt grouting, etc. 2, suitable for all kinds of mechanical and electrical equipment ( Heavy equipment, high-precision grinding machine) The primary and secondary grouting.   The main technical indicators & # 8195; Product model (compressive strength MPa） Vertical expansion ratio ( Qingdao development zone of cement grouting material) % Fluidity ( mm） Slump ( mm） Water material ratio ( %)   2 hours a day for three days, 28 days repair engineering special acuity 15 or 22 ~ 27 38 ~ 45 or 70 p 0 or higher. 02300 ~ 380/13% ~ 15% of jining grouting LiaoChang household method ( A) Foundation treatment and shuttering: 1, the surface of the concrete foundation cut hair, and make it clean. With the components of paste together ( Such as steel plate) Will rust skin and remove such as oil. 2, 4 to 24 hours before in water slurry, on the surface of a concrete foundation to wet, when watering can not have water. 3, damper should be set tight, prevent leak slurry. （ 2) Grouting: 1, the water content: according to each bag ( 25公斤) Water 3. 1 - 3. 5 kg water mixing proportion, such as the construction does not need large fluidity can reduce water consumption accordingly. 2, mixing procedures: in the mixing barrel to join after the specified amount of water into blender, will be part of the dry ingredients into mixing barrel, and then into the mix, the time from start to finish should be controlled in 3 ~ 5 minutes. 3, mixing, blade should be to move slowly from side to side, up and down on the barrels around so that the bottom and the barrel wall adhesion to the mixing of dry material; Mixing blade shall not to a pulp level, so as to avoid air into a pulp. 4, watering, as far as possible from the side of the injection, and discharge the air between the base plate and concrete foundation. When necessary, can use the tools such as bamboo diversion. After the start of casting must be continuous, not continuous. （ 3) Maintenance: 1, covered with wet straw bag or cloth in pour out has good sizing agent, and water conservation, 2 ~ 6 times a day. 2, curing temperature should be in more than 15 ℃, 7 days curing period. If the scene at low temperature can be appropriately extended curing period. 3, the winter construction need to heat preservation measures. 4, ripping open mould should be finished in water for 24 hours, and continue to maintenance after ripping.   Packaging and storage and transportation packaging specifications for 50 kg + 0. Grouting material 25 kg, with composite kraft paper bags. Store in a dry, shady and cool place, without be affected with damp be affected with damp save the storage life for six months. Are need to recheck, just can use after qualified.
