Each of these techniques have inherent advantages and disadvantages which […]

Impregnation Technique Extends the Service Life of Post-Tensioned Bridges with Grout Defects

Problems with grouting techniques and grout materials has resulted in grout voids, chloride contaminated grout, and segregated grout. Subsequently corrosion of the PT tendons can occur and some tendons […]

Durability Design for Concrete Immersed in Seawater or Brine.

Hence, Australian Codes have much lower prescriptive requirements for immersed concrete than for concrete in the splash […]
