<p>[Problem] To provide a porous concrete having fluidity, which can be used for constructing water-permeable structures having various shapes utilizing boreholes or the like even in soil that is below the groundwater level. [Solution] A porous concrete having fluidity which is characterized as follows. Aggregates each having a spherical shape are used in the concrete so as to eliminate the orientation of the aggregates and unify the mode of contact between adjacent any two of the aggregates, thereby imparting fluidability to the concrete and enabling the pumping of the concrete through a pipe. And each of the aggregates is coated with a poorly water-soluble binder and the aggregate contact parts are consolidated. This constitution enables the construction of water-permeable structures having various shapes in soil in which groundwater exists.</p> |
