Post-Tensioning Grout Bleed, Duct, and Anchorage Protection Test
Due to substantial problems with product quality, the Department is revising all specifications concerning post-tensioning corrosion protection. New products for grouting post-tensioning ducts have recently become available. These new products must be thoroughly tested before general application. Bleed testing was conducted at the FDOT Structures Research Center in Tallahassee using four prepackaged grouts, each from a different manufacturer. The selected grouts were: Euclid Euco Cable Grout PTX, Master Builders Masterflow GS 1205, Five Star Special grout 400, and Sika Cable Grout. Vertical pipes were constructed with clear PVC and were injected with grout and monitored for bleed over the next 24 hours. Two inclined tests were performed using the same pipe. Three horizontal corrugated ducts were also grouted to evaluate the effect of the corrugations on the extent of grout. Finally, laboratory tests were conducted on the bleed properties of the prepackaged grouts used in the grout tests.
