Mass precast concrete elements for columns and beams have been developed in recent years to improve the quality of reinforced concrete structures and simplify their methods of construction. The object of this work was to study the temperature history of mass precast concrete elements in their production process. By heat curing from the outside and internal storage of the heat of cement hydration, the mass precast concrete elements showed different temperature history from the thin precast concrete elements for walls and floor slabs. The temperature history at the center of mass precast concrete elements was different from that at the surface of mass precast concrete elements. A larger section size of elements resulted in larger difference in temperature between the center and the surface of mass precast concrete elements.
