Concrete raw material, top surface bubble-free concrete sleeper pouring method and application

The invention belongs to the technical field of building materials, and particularly provides a concrete raw material. The concrete is prepared from the following raw materials in percentage by weight: 20 to 33 percent of sulphoaluminate cement, 2 to 8 percent of silica fume, 0.5 to 3 percent of polymer emulsion, 0.05 to 0.15 percent of water reducing agent, 0.01 to 0.06 percent of retarder, 0.03 to 0.10 percent of early strength agent, 0.01 to 0.06 percent of expanding agent, 0.01 to 0.09 percent of defoaming agent, 0.04 to 0.11 percent of anti-settling agent, 0.05 to 0.13 percent of fiber, 27 to 33 percent of sand and 29 to 40 percent of broken stone. According to the concrete sleeper pouring method free of the bubbles on the top face, in the operation high-speed railway double-block ballastless track sleeper damage treatment project, the performance requirement of the concrete material is met, and the construction effect that the surface of cast-in-place sleeper concrete is free of the bubbles after demold
