Bearing mortar is a special early-strength and high-strength type for high-speed railways
Bearing grouting material
Bearing mortar bearing grouting material The bearing self-leveling mortar series is an industry-leading product, which contains reasonable fractions of high-strength silicon. The above aggregates are aggregates, high-strength cement is used as the binding agent, high molecular polymer is used as the toughening agent, supplemented by high fluidity, micro-expansion, anti-segregation and anti-cracking admixtures and other admixtures, which are professionally produced with precise proportions. .
Bearing mortar is a high-quality cement-based composite material used for the installation of railway bridge bearings. Thanks to the use of a variety of high-performance additives, the finished surface is particularly smooth and flat. It overcomes the shortcomings of traditional mortar such as uneven cracking and peeling, and has the characteristics of self-leveling, high early strength, no shrinkage, high wear resistance and convenient construction.
The performance indicators are in line with national and railway industry standard technical requirements such as the "Details for the Implementation of High-Performance Concrete on the Beijing-Shanghai High-Speed Railway" and the "Interim Technical Conditions for Basin Rubber Bearings for Bridges on Passenger Dedicated Lines" issued by the Science and Technology Base.
