RESIN CONCRETE COMPOSITION, RESIN CONCRETE HARDENED PRODUCT, AND FIBER-REINFORCED PLASTIC COMPOSITE PIPE
To provide: a resin concrete composition capable of improving strength of fiber-reinforced plastic composite pipes by a composition of resin concrete composition only; a resin concrete hardened material; and a fiber-reinforced plastic composite pipe.SOLUTION: A resin concrete composition includes an aggregate and a thermosetting resin, and the aggregate satisfies the following conditions. When the most frequent particle diameter is a particle diameter (1) among the particle diameters with a cumulative frequency of 80% or less from the small diameter side of the aggregate volume basis, and when the most frequent particle diameter is a particle diameter (2) among the particle diameters with a cumulative frequency of more than 80% from the small diameter side of the aggregate volume basis, the proportion of the particle diameter (1) in the frequency distribution is 15% or more, the proportion of the particle diameter (2) in the frequency distribution is 15% or more, a ratio of the volume fraction of the particle diameter (2) to the particle diameter (1) is 0.60 or more and 1.5 or less, and a ratio of the particle diameter (1) to the particle diameter (2) is 0.3 or less.SELECTED DRAWING: None
