Abstract
The invention has an object to provide a heavyweight fine aggregate and a heavyweight aggregate for a stiff heavyweight concrete having a slump of 0 to 3 cm, in which segregation from the cement paste is unlikely to occur, and to provide a stiff heavyweight concrete having a slump of 0 to 3 cm, using the heavyweight fine aggregate and heavyweight aggregate. The heavyweight fine aggregate comprises no less than 20 wt % of aggregate having a particle size smaller than 0.15 mm, and no less than 20 wt % of aggregate having a particle size from 2.5 mm to less than 5 mm. The above feature allows effectively inhibiting segregation between the aggregate and cement paste when blending the aggregate into the heavyweight concrete, and allows effectively increasing the filling rate in boxes when blending the aggregate into the heavyweight concrete for box filling.
