This paper presents a new approach to recognize a long-term strength of concrete. We introduce into the calculation a new concept of energy integrity of the specific energy of W-maximum resistance to the destruction. In the formation and aging process the concrete is considered to be a non-conservative system. Strength development implies the increasing of the demanded specific work for fracture. The results of the calculations show that for critical reinforced concrete constructions operate at a significant level of long-term loading. The coefficient of the working conditions should be given as differentiating, taking into account the predicted concrete creep.
