Abstract

During 1984 summer, an experimental concrete column was cast in a 26-story high-building using a 100 MPa silica fume concrete. Only the coarse aggregate was selected specifically for this concrete. The cement used was an ordinary type 1 Portland cement. The superplasticizer was a naphthalene base. The field conditions were among the most unfavourable, the transportation was about 3/4 of an hour. The placing lasted 15 minutes. However, after 1 h 00 the slump of this concrete having a water/cementitious ratio of 0.25 was still higher than 100 mm so that the concrete was placed without any problems.
