BLASTING RESISTANT HIGH STRENGTH CONCRETE AND METHOD OF MANUFACTURING BLASTING RESISTANT HIGH STRENGTH CONCRETE |
摘要 |
PROBLEM TO BE SOLVED: To provide blasting resistant high strength concrete which is not required to cover its surface with heat insulating material or the like, has little fear of a deterioration in and ununiformity of strength and of the lowering of fluidity when placed into molds and can be placed into molds with a process similar to the conventional placement process. SOLUTION: When the blasting resistant high strength concrete 1 is exposed to high temperature environment by fire or the like, organic powder 2 is heated to reach the melting point and melted to reduce the volume to form gaps 4 in parts occupied by the organic powder 2. The rupture is prevented by reducing the volume of the organic powder 2 and forming many discontinuous independent gaps 4 to uniformly disperse in the blasting resistant high strength concrete. The organic powder 2 consists of polypropylene (PP) of an organic compound processed into a particle having 10-200μm particle diameter. COPYRIGHT: (C)2004,JPO
