Sales hotline: (Mr. Li) Bearing mortar is a high-performance polymer-modified cement-based grouting material that uses a variety of organic and inorganic additives and has the characteristics of super early strength, high strength, no shrinkage, and high wear resistance. 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, highways, etc.
1. Product features:
High flow state can completely self-flow leveling, no need for 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.
It has very high hourly strength, high late strength and no shrinkage. According to different construction temperatures, high compressive strength and high flexural strength can be obtained in hours.
. 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, 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.
, complies with the requirements of the "Interim Technical Conditions for Concrete Precast Beams for Passenger Dedicated Lines" and the "Temporary Technical Conditions for Pot-type Rubber Bearings for Bridges on Passenger Dedicated Lines".
2. How to use:
Base surface treatment: Remove dust, oil and other dirt that are not conducive to bonding 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 no residue should be left during construction. There is clear 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.~
Stirring: first add water to the mixing barrel, then gradually add the weighed grouting material, and use it while adding the material Use an electric mixing gun to stir until all the powder is added, and then 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 3 minutes after mixing is completed.
Note: Do not add water again to mix and stir the slurry that cannot restore fluidity before use.
