The invention discloses a mass concrete temperature control and shrinkage compensation method, and belongs to the technical field of temperature control and crack control in concrete construction, and the method specifically comprises the following steps: preparing cold storage units, and uniformly adding the cold storage units into a concrete base material according to the volume of the concrete base material; and organic microcapsules with thermal expansion and cold contraction characteristics are contained in the cold storage units. The phase change characteristic of the quick-freezing concrete cold storage unit is ingeniously utilized for temperature control, the deformation characteristic of thermal expansion and cold contraction of a capsule material is utilized for shrinkage compensation, the size and the shape of the cold storage unit can be designed according to a reinforcement cage, a brand new technical scheme is provided for temperature control and crack control of mass concrete, and the method is
