High-speed rail-specific cement

Meeting the highest construction standards for China’s high-speed rail projects, this is a custom-formulated cement exclusively for precast high-speed rail beams. It features low hydration heat, resulting in minimal overall shrinkage after concrete placement. It offers freeze-thaw resistance, high impermeability, and high density. Once the structure is formed, it exhibits an extremely low coefficient of deformation and exceptional load-bearing capacity, fully complying with the stringent technical requirements for the precasting of high-speed rail box girders and T-beams. Supplied exclusively to major high-speed rail girder yards, this cement is used for core high-speed rail infrastructure projects, including the precast pouring of high-speed rail bridges and the main load-bearing structures of elevated high-speed railways.
