After the earthquake repair of high-strength non-shrink grout material characteristics

The characteristics of the grouting material modified grouting material is a kind of post-earthquake by high-strength cementitious materials, various and beautiful seam an agent composite, selected aggregate manufactured by special technology, with large activity, shorten, early strength and high strength after the bursting of the characteristics of the fixed special high strength grouting material. In cement-based cementitious materials, mineral admixture, high performance and beautiful seam an agent, such as the factory produce. Below the water mixing evenly into the bolt hole and trajectory, arrived in upper part of the uniform load transferring to accept all kinds of force, in the port, wharf, can improve the durability of high speed railway, shorten the construction period, disaster relief, by pollution. Applied range: 1, port, wharf crane track groove grouting. Track plate, bottom 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. Using the method ( A) Root processing and shuttering: 1, cut hair root surface of concrete, and its finishing clean. With the components of paste together ( Such as steel plate) Clear the scale and oil etc. 2, 4 to 24 hours before irrigation block size, root surface of concrete to wet, can not have water irrigation. 3, damper should be set tight, prevent leak slurry. （ 2) Grouting: 1, add water: in accordance with each bag ( 50公斤) Water 6 - The proportion of 7 kg water mixing, such as construction don't need a large activity can reduce water consumption accordingly. 2, mixing procedures: participate in the specified amount of water in the mixing barrel after placing mixer, will be part of the dry ingredients into mixing barrel, float the remaining material mixing, and time from the beginning to the end should be controlled in 3 ~ 5 minutes. Around 3, mixing, blade should be along the barrel at the mercy of slowly moving up and down, so that the bottom and the barrel wall adhesion to the mixing of dry material; Mixing blade shall not to a pulp level, avoid air into a pulp. 4, irrigation, 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 pouring start necessary in succession, not continuous. （ 3) Maintenance: 1, cover with wet straw bag or cloth at the slurry has good irrigation, watering and maintenance, 2 ~ 6 times a day. 2, maintain temperature should be in more than 15 ℃, the maintenance period of seven days. If the scene at low temperature can be appropriately extended maintenance period. 3, the winter construction need to adopt heat preservation measures. 4, ripping open mould should be finished in irrigation for 24 hours, and continue to maintain after ripping. Packaging and storage and transportation packaging standard for 50 kg + 0. 25 kg, with a composite paper bag lined with plastic bag. 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.
