PROBLEM TO BE SOLVED: To provide a judgment method which enables accurate judgment of cracking in the premature age of member using high strength concrete, a cracking judging device and a casting method of the high strength concrete which accurately prevents cracking.;SOLUTION: A self-contraction stress calculation means calculates the self- contraction distortion and the self-contraction stress of concrete based on the temperature and effective material age (S6, S8). The correctness of the self contraction stress obtained considering the temperature of the concrete enables accurate determination of tensile stress a generated in the concrete of the concrete member (S10) and hence, it can be judged accurately whether cracking occurs in the concrete member (S12). As a result, the concrete member without cracking at any premature material age can be obtained by following a curing method and a curing period determined with the device adapted to determine the curing method and the curing period of the member using the high strength concrete.;COPYRIGHT: (C)2002,JPO
