Abstract:
This paper describes the use of condensed silica fume in the ready-mixed concrete plant at St. Eustache, P.Q., Canada. The effect of this admixture on the properties of fresh and har-dened concrete is discussed. Efficiency factors for the silica fume-modified concrete are given for different strength levels. Transportation of the fume and special installations at the ready-mixed concrete plant for the handling of condensed silica fume are described.
