    Abstract: PROBLEM TO BE SOLVED: To provide high strength and extra-high strength concrete and high strength and extra-high strength concrete structure which enables explosive fracture suppressing action to be properly secured.
    SOLUTION: A latent heat effect development material for decreasing the temperature increase ratio of the high strength and extra-high strength concrete exposed under a high temperature atmosphere with time by the latent heat effect of absorbing heat in the melting and the vaporization by the heating to 450°C is incorporated with the high strength and extra-high strength concrete. As the latent heat effect development material, a high polymer compound having a heat decomposition temperature lower than 450°C is preferably used. An outer shell PCa concrete member constituting a structure such as columns, beams or walls is made from the high strength and extra-high strength concrete. The high strength and extra-high strength concrete structure is formed by placing and filling concrete having strength higher than that of regular concrete in a space formed by the outer shell PCa concrete member and integrating the outer shell PCa concrete member with a surface layer part.
