The invention relates to a steaming-free concrete prefabricated assembly. The steaming-free concrete prefabricated assembly is characterized in that an inorganic-organic composite early strength agentand a nucleus-type early strength agent are simultaneously added to a concrete prefabricated assembly raw material according to a certain proportion to improve the early strength of the concrete prefabricated assembly, so that a steaming process can be avoided, energy consumption is reduced, energy is saved, the internal compactness of the concrete is improved, the flatness of the concrete surface is increased, crack formation is avoided, the later strength of the concrete is maintained, and the overall strength of the concrete is improved.
