Abstract
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 strength of mass precast concrete elements. The mass precast concrete element showed different strength from the thin precast concrete element cured under the same heating condition. This is attributed to the difference in temperature history caused by the internal storage of heat of cement hydration in the mass precast concrete element. Using the maximum temperature as a parameter, the strength could be uniformly predicted regardless of the section size and the position of precast concrete elements.
