What are the typical features of pedestal grouting material and pedestal grouting material construction and maintenance method is what

Bearing grouting support grouting material manufacturer we all know, early strength type bearing grouting material is one of the industry's leading products, it at a reasonable level points of high strength aggregate as aggregate, high strength cement as in combination with the seam an agent, polymer toughening the seam an agent, complementary with high flow, micro expansion, segregation, cracking resistance and beautiful seam an agent, such as admixtures such as accurate. Specializing in the production of dry mixing proportion. Then you should also don't know, what are the typical features of pedestal grouting material, pedestal grouting material construction and maintenance method is what? Here, we might as well let's follow the small make up together to see the specific content. Bearing grouting material has what characteristics: 1, has excellent liquidity, gravity leveling, without vibration, pressure, construction speed is quick and convenient. 2, high hours late strength, high strength, not shrink. According to the different construction temperature, can obtain 20-2 hours 40 mpa compressive strength, flexural strength is high. 3, with micro expansion properties and excellent crack resistance. 4, to adapt to the wide temperature range and in - 5℃～- 35 ℃ under the condition without any auxiliary insulation or cooling measures can the construction. Under the condition of high temperature or low temperature, can guarantee the strength at the same time the needs of the development and construction of liquidity. 5, suitable for repair, track filling, support grouting, especially suitable for high speed railway bridge bearings or orbital filling etc. Can also be used for concrete beam local leveling or repair of the concrete pier. What pedestal grouting material construction and maintenance methods are: 1, 24 h before the construction should be fully wetting at the grass-roots level, should guarantee the basic no MingShui when grouting; 2, before the grouting should be set template and check the sealing, prevent leak slurry during grouting and grouting quality; 3, USES forced mixer mixing: in accordance with the recommended water metering well water, add about three-quarters of the water first 1 ~ 2 minutes, add the remaining water continue to stir until smooth, the mixing time control within 5 minutes. A mixing volume shoulds not be too much to used up within 20 minutes advisable. 4, using hand electric drill: stir to mix water and about three-quarters of material into the barrel, mixing for 30 seconds and then pour the remaining material evenly, according to the power of the hand electric drill and rotational speed, the mixing process takes about 1 ~ 2 minutes; Stir well after grouting material if the surface has a large number of air bubbles, should let stand for 1 ~ 2 minutes, after waiting for air bubbles eliminate again for grouting; 5, grouting the exposed portion after the completion of the grouting material should be timely moisture curing covering plastic film or wet straw bag, after waiting for grouting material hardening for water conservation, ensure grouting material surface wet, curing time should not less than three days. What about bearing grouting material characteristics, and pedestal grouting material construction and maintenance method is what of relevant knowledge, small make up just to tell you so much. Normally, pedestal grouting material used in railway bridge bearing installation of high quality cement base composite material, at present, the domestic bearing grouting material because of its beauty USES a variety of high-performance add seam an agent, special finished surface smooth level off, overcomes the traditional mortar uneven, shortcomings and so on crack, flake, has high strength, no shrinkage, high wear resistance and construction is convenient wait for a characteristic.
