Bearing mortar is a special cement mortar, which is composed of a variety of inorganic and organic materials. This product is a high-quality cement-based composite material used for the installation of railway bridge bearings. Because it uses a variety of high-performance additives, the surface after completion is particularly smooth and flat, overcoming the shortcomings of traditional mortar such as unevenness, cracking, and peeling. It has the characteristics of self-leveling, high early strength, high strength, no shrinkage, high wear resistance, and convenient construction. . It is suitable for emergency repairs, support anchoring, secondary grouting of anchor bolts and bases of large equipment and precision equipment, secondary grouting of steel structures and concrete consolidation, secondary reinforcement of beams and columns, etc. It is especially suitable for high-speed railways and passenger transportation. The performance indicators of the bearing grouting for dedicated line and highway bridges meet the technical requirements of the "Interim Technical Conditions for Basin Rubber Bearings of Passenger Dedicated Line Bridges" and the "Interim Technical Conditions for Cylindrical Steel Bearings of Passenger Dedicated Line Bridges" issued by the Science and Technology Base.
1. Usage and storage: Base surface treatment: The base surface to be grouted should be cleaned of dust, oil, other dirt and other substances that are not conducive to bonding. The base surface should be pre-wetted an hour in advance. No clear marks should be left during construction. water.
Use gravity grouting to fill the gaps at the bottom of the support and the anchor holes. The grouting process should be from the center of the support to the surroundings until the grouting material is completely filled from the gap between the formwork and the bottom plate of the support. The amount of mixing each time should depend on the usage, and the material should be used up within 3 minutes.
