Early strength high strength bearing mortar (CGM-100t series) is an industry-leading products, it is a reasonable fraction of the aggregate of aggregates of high intensity, high strength cement as binding agents, polymers as toughening agents, supplemented high flow, micro-expansion, anti-segregation, cracking and so additives, admixtures and other professional production made precise ratio of dry mixture. Early strength high strength mortar bearings for high-quality cement based composites railway bridge bearing installation. Because of its use of a variety of high-performance additives, especially after the completion of the surface smooth. Uneven overcome the traditional mortar, cracking, spalling and other shortcomings, with self-leveling, high early strength, high strength, non-shrink, high wear resistance and easy construction and other characteristics. Its performance indicators in line with "the Beijing-Shanghai high-speed railway facilities of high performance concrete implementation details" and "Railway Bridge rubber bearing basin interim technical conditions" and other national standards and technical requirements of the railway industry.
