Problems solved by technology

[0002] At present, most of the track cement on the market is produced according to the standards of JC / T986--2005 "Industry Standards for Grouting Materials" and YB / T9261-1998 "Technical Specifications for Construction of Cement-based Grouting Materials". The fluidity is about 270mm, 1d, 3d, 28d The strength is ≧22Mpa, ≧40Mpa, ≧70Mpa, the strength is low, the initial fluidity is not high, and it cannot meet the requirements of some projects such as railway tracks, supporting tracks of port tower cranes, industrial plants and other projects. Project requirements for wharf crane track grooves and other engineering requirements for ultra-high-strength engineering construction
