SPALLING-PREVENTABLE ULTRA-HIGH STRENGTH CONCRETE

摘要

PROBLEM TO BE SOLVED: To provide ultra-high strength concrete having a compression strength of 150 N/mm2and capable of preventing spalling.

SOLUTION: The ultra-high strength concrete is prepared by mixing hollow thermoplastic fibers and/or porous thermoplastic fibers and/or porous hollow thermoplastic fibers into concrete to suppress spalling. In the ultra-high strength concrete, steel fibers are mixed in addition to the thermoplastic fibers to suppress spalling.
