High-speed rail bridge bearing points of the dry-mixed mortar and characteristic is what? How much do you know?

High-speed railway bridge bearings, mortar mortar mortar support high-speed bearing manufacturers with the rapid development of the tourism industry in our country, drive the high-speed development of each region of the passenger dedicated line, said to us today is to build a passenger dedicated line used to a kind of grouting material, it is support mortar. Bearing mortar is a kind of suitable for high speed railway and the special line for passenger transport, highways, and other road bearing grouting material, what its construction characteristics and the key is that? Early strength type bearing grouting material is a leading professional 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. Professional production of dry mixing proportion. Support key, there are two of the dry-mixed mortar, the first processing and shuttering construction is the key foundation, has the following three points we need to consider. （ 1) Cut hair appearance of concrete foundation, and finishing it clean. With the components of paste together ( Such as steel plate) Will rust skin and remove such as oil. （ 2) Four hours before in irrigation slurry, appearance of concrete foundation to wet, can not have water irrigation. （ 3) Damper should be set strict, avoid leak slurry. The second key is grouting construction, which is the most important. Need to know friends can see. （ 1) Add water: according to each bag ( 50公斤) 7 ~ 8 kg of water mixing water, such as the construction does not need large fluidity can reduce water consumption accordingly. （ 2) Mixing procedures: placement after join the specified amount of water in the mixing barrel mixer, will be part of a slurry stirring dilute inside bucket, float the remaining material mixing, and time from the beginning to the end should be controlled in a minute or so. （ 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 bridge above the liquid level to avoid air into paste paste. （ 4) Good mixing cement paste should be timely irrigation. Irrigation, as far as possible from the side of the injection in order to discharge the air between the base plate and concrete foundation. When necessary, can use the tools such as bamboo diversion. Must be conducted in succession after beginning irrigation, it is not. On about bearing about the key of the dry-mixed mortar, the pedestal mortar can be used as a railway or high-speed rail construction, that is because other materials has its own irreplaceable function, then, will explain some characteristics of bearing mortar is its special: 1, excellent mobility, gravity leveling, without vibration, pressure, construction speed is quick, convenient. 2, high hours late strength, high strength, not shrink. 3, according to the different construction temperature, 20-2 hours 40 mpa compressive strength, flexural strength is high. 4, has the function of micro expansion and excellent resistance to cracking. Habit wide temperature scale, under the condition of 5 ℃ ~ 35 ℃, without any auxiliary heat or cool way can the construction. 5, under the condition of high temperature or low temperature, can guarantee the strength development and construction of liquidity needs. 6, used to repair, trajectory filling, pedestal grouting, especially the high-speed railway bridge bearings or right track filling, etc. Can also be used for concrete beam section leveling or repairing concrete pier. Above give us specific bearing mortar are introduced two key construction and its six major characteristics, when user in choosing grouting material can do not prevent consider bearing mortar, in fact, after understanding the above these basic information, must be to choose, to choose what kind of information they want, the in the mind noodles have the conclusion, want to know more about the grouting material and bearing mortar related content, to call detailed consultation hotline: 15838304411
