The invention belongs to the technical field of ballastless track construction and especially relates to a thixotropic agent for concrete of a bed-plate at the curve superelevation section of a ballastless track. In allusion to the problem that drainage slope and curve superelevation are not easy to control during pouring of concrete of a bed-plate at the curve superelevation section, a thixotropic agent for improving shape retaining ability of fresh concrete is invented. The thixotropic agent comprises the following ingredients (by weight): 0.5-4 parts of attapulgite, 0.5-5 parts of meerschaum, 0.02-0.38 part of fumed silica, 2-30 parts of silica fume, 0.06-0.5 part of triterpenoid saponin, 0.03-0.5 part of cellulose ether and 0-2.5 parts of fiber. By the use of the thixotropic agent, static morphological stability of fresh concrete can be greatly promoted, and slope fixing forming can be realized after pouring. Meanwhile, dynamic deformation energy is not increased, and concrete has good rheological performance during constructions of pumping, pouring, vibrating and the like and is convenient for construction. The product of the invention is of great significance for ensuring construction quality control of drainage slope and curve superelevation of the ballastless track bed-plate.
