Abstract:

This report covers the execution and results of studies supplementing those given in report No. 1. The present work included development of additional concrete mixtures containing silica fume and high-range water-reducing admixtures HRWRA. Abrasion-erosion testing was done on specimens from some mixtures. Trial placements of two such mixtures were made and reviewed. Finally, assistance was provided to the US Army Engineer District, Pittsburgh in preparation and review of specifications for this project. It was concluded that the overall objective of providing concrete with a high degree of resistance to abrasion-erosion damage had been met. While these initial specifications were generally satisfactory, future ones will require some modification based on what has now been learned. Several questions regarding the use of silica fume were raised.
