Abstract:Starting in 1984, steel fibre reinforced concrete (SFRC) jackets have been placed around distressed hollow core octagonal concrete piles at the Rodney Terminal wharf, Saint John, New Brunswick. The placement has been by pumping the SFRC into steel forms around the piles. The pumping and pipeline equipment, steel fibres and concrete admixtures have evolved over the years to solve problems, initially with the placement by pumping over a long pipeline and subsequently with the control of air to provide acceptable strength and air void parameters for freeze thaw resistance. This paper describes the experience with this unique method of repairing piles and concludes that, in spite of requiring constant attention to quality control, this is a simple method of repair.
