To provide a civil engineering/building material having a high void content which is applicable to a civil engineering/building structure that needs a high void content so as to exhibit excellent water permeability and needs durability such as high compressive strength or the like by utilizing reformed sulphur and a specific coal ash particulate material having a generally spherical shape, and to provide a drain material for a dam body having a high void content that enables to rapidly drain penetrated water from sea, rivers, etc. to the dam body and also excellent in durability such as acid resistance, high compression strength or the like.
The inventive civil engineering/building material having a high void content or the drain material for a dam body is a material which has a void content of 25-50% and is obtained by coating, bonding and solidifying each of a coal ash particulate material having a diameter of 2-50 mm which contains 100 mass% of a coal ash and 10-100 mass% of an electric furnace reduction slag with a fluid material having a particle diameter of at most 1 mm and containing reformed sulphur which contains 100 mass% of fine powder and 30-400 mass% of reformed sulphur.
