Abstract:
PROBLEM TO BE SOLVED: To provide a concrete building structure which has a form without remarkably damaging bearing strength characteristics while remarkably improving thermal insulation properties, and a block type thermal insulation structure to which the building structure is applied. SOLUTION: The thermal insulation structure 1 between two concrete members is connected to both concrete members, and provided with reinforcing materials 5, 6, 7 and an insulator 4 for transmission of shearing force or moment, or both of them between the concrete members. One of the reinforcing materials is connected to the concrete members so as to receive pressure as a pressure resistant material 7. High-strength concrete which is formed as a thermal insulating support building structure by making a titanium mineral to be contained in the pressure resistant material 7 as an additive is used as the pressure resistant material 7.

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.

Abstract:
A composite pavement structure comprises a wearing course layer and a base course layer disposed below the wearing course layer. The wearing course layer comprises aggregate, e.g. glass and rock, and an elastomeric composition. The elastomeric composition comprises the reaction product of an isocyanate component and an isocyanate-reactive component. The isocyanate component comprises a polymeric isocyanate, and optionally, an isocyanate-prepolymer. The isocyanate-reactive component comprises a hydrophobic polyol and a chain extender having at least two hydroxyl groups and a molecular weight of from about 62 to about 220. The chain extender is present in the isocyanate-reactive component in an amount of from about 1 to about 20 parts by weight based on 100 parts by weight of the isocyanate-reactive component. The base course layer comprises aggregate which is the same or different than the aggregate of the wearing course layer. Methods of forming the composite pavement structure are also disclosed.
