COMPOSITION FOR CONCRETE, MOLDED PART OBTAINED BY MOLDING THE SAME, AND FLOOR SLAB

摘要

PROBLEM TO BE SOLVED: To provide a composition for concrete excellent in resistance to composite deterioration of freezing damage and fatigue, a molded part obtained by molding the same, and a floor slab.SOLUTION: Provided is a composition for concrete comprising: a fine aggregate including a blast furnace slag fine aggregate; a binder including cement; and water, in which, in the case where a freeze-thawing test 30 cycle based on the A method described in the JIS A 1148 to a concrete test piece produced by the composition for concrete and a fatigue test 200,000 cycles caused by a repeated load under prescribed load conditions are repeatedly performed, it has a high durability not destroyed even in the fatigue test 1,600,000 cycles.SELECTED DRAWING: None
