>Contact number of bearing grouting material manufacturer
Bearing grouting material is a high-performance polymer-modified cement-based grouting material. It uses a variety of organic and inorganic additives and has super early strength, high strength, no shrinkage, and high Wear-resistant properties. This product has good construction performance, can self-flow leveling, can be operated for a long time, and has a smooth and flat surface after completion, overcoming the shortcomings of unevenness, cracking, peeling and powdering caused by traditional mortar. It is suitable for emergency repair, bridge bearing anchor grouting, track anchor grouting, etc. It is especially suitable for bearing grouting of high-speed railways, passenger dedicated lines, expressways, etc.
High-speed rail bearing grouting material is a high-performance polymer-modified cement-based grouting material that uses a variety of organic and inorganic additives.
The grouting material for high-speed railway bearings should have the characteristics of super early strength, high strength, no shrinkage, and high wear resistance. It should have good construction performance, be able to self-flow leveling, and have a long operating time. The surface should be smooth and flat after completion. Overcome the shortcomings of unevenness, cracking, peeling and powdering caused by traditional mortar.
Other applicable occasions for bearing grouting material
It should be suitable for emergency repair, bridge bearing anchor grouting, track anchor grouting, etc.
Features of the bearing grouting material
It has high fluidity and is fully capable of self-flowing leveling. It does not require vibrating and troweling, and the construction is convenient and fast.
, Good workability, not only good fluidity but also long-lasting cohesion, no delamination, no bleeding.
. Intelligent water retention. During the initial setting time, when the mixed mortar is not used for a long time and is in a static state, it can automatically form a water retention structure, temporarily lose the flow and lock the water, thereby preventing the mortar from being damaged. Stratification and bleeding. When used again, the flow can be restored with just gentle stirring, and there is basically no loss of fluidity.
, no shrinkage, micro-expansion properties, dense structure after hardening, no shrinkage and cracking.
, Early strength and high strength. The hourly strength of compressive and flexural resistance is very high, and the late strength is super high without shrinkage.
, better wear resistance and toughness.
, easy to use, the finished product is dry mixed mortar, which can be used after adding water and stirring at the construction site. []
How to use bearing grouting material
Treat the base surface to remove dust, oil, other dirt and other substances that are not conducive to bonding. Repair cracks and other defects. The base surface should be moistened with clean water until it is saturated, but it should not be used during construction. There should be open water.
Calculate the amount of powder and water consumption based on the construction area or construction area per unit time. The amount of each mixing should ensure that all construction is completed before the mortar loses leveling properties.
, Mixing ratio (weight ratio) water-powder material
, Stirring: First add water into the mixing barrel, then gradually add the weighed grouting material, stir with an electric mixing gun while adding the material, until the powder is After all is added, continue stirring for another minute to make the slurry uniform.
Pour the mixed slurry evenly onto the treated base surface and let it level itself. Leveling should be completed within the construction time, and the equipment should be rinsed with water immediately after construction.
The construction time depends on the ambient temperature. At ℃, it is within minutes after mixing is completed. Note that slurries that cannot regain fluidity should not be mixed with water again before use.
