Document Type and Number:
Japanese Patent JP6889478
Kind Code:
B2
Abstract:
To provide a concrete composition which is possible to cure at atmospheric temperature and atmospheric pressure and of which high toughness and high durability are expressed early.SOLUTION: The concrete composition of the invention is a concrete composition which at least includes cement, fly ash or silica fume, aggregates, water, water-reducing agent, air volume moderator and reinforcement material. The reinforcement material consists of a three-dimensional structure constructed by crossing metal wires in a mesh shape without being fixed to each other, has a compressive strength by compression test (JIS A 1108) of 100-130 N/mmand fracture energy of 70-150 k Nm/mwhich is defined by the area of the bending deflection curve according to the bending strength test (JIS A 1106).SELECTED DRAWING: Figure 2
