Description: Miscellaneous Paper
Abstract: The work described in this report involved abrasion-erosion testing of several concrete mixtures containing silica fume to evaluate the relative potential of the several mixtures to resist such attack. The mixtures were candidates for use in repair work to be conducted by the US Army Engineer District, Los Angeles. Concrete was placed in the field between 21 and 23 September 1983. Conclusions included (1.) the mixtures tested could provide excellent resistance to abrasion-erosion damage; (2.) no more than 15 percent fume should be used; (3.) mixtures were difficult to place and required special attention but were worth the extra effort; and (4.) concretes containing silica fume appear to offer the best resistance to abrasion-erosion damage.
