Slide 1

´╗┐Sturdiness of Post-Tensioned Structures Grout Specifications Durability Design Details

Slide 2

Durability and Post-Tensioning dampness, Cl - , CO 2 Extremely solid when legitimately built Crack control Multiple insurance levels solid pipe grout The grout is the last level of assurance for the strand

Slide 3

Purpose of Grout Corrosion security Bond

Slide 4

Properties Fluidity Bleed Segregation Set Time Strength Permeability Volume Change Corrosion Protection Bleed

Slide 5

Bleed in Grouts Bleed water is caught in conduit Higher vertical ascents = higher weights and more drain water Strand advances seep by wicking Intermediate lense

Slide 6

Bleed Lenses Voids Loss of defensive condition 9 ┬ż" drain segment Intermediate lense

Slide 7

Keys to a Good Grout Completely fills pipe Low penetrability Appropriate drain resistance Careful utilization of admixtures Many admixtures help one grout property while corrupting another

Slide 8

Tasks under WO-81 Literature survey and synopsis of flow practice Development of determination dialect, points of interest, and amendments to PennDOT productions Scope incorporates Grouting (materials, systems, venting) Durability subtle elements (mooring, channel material) Inspection/repair Training of staff
