Transcript and Presenter's Notes

Title: Rigid Foam


1
Rigid Foam
  • Anelise Williamson
  • MEEN 3344
  • 11-1-04

2
Prime Flex 985
  • Urethane Resin
  • Lightweight, rigid foam
  • Two components

3
Common Uses
  • Slab stabilization from beneath
  • Filling of Voids in wet areas
  • Closing up abandoned pipelines or storage tanks.

4
Benefits of this Material
  • A relatively fast setting time
  • Very low viscosity
  • Can be used in wet situations (retaining wall)
  • It will bond with the sub soils

5
Physical Properties at room temperature
  • Mixing Ratio is (11)
  • Viscosity is 300-450 cps
  • It takes about 8 minutes to set
  • Expands at a ratio of 201
  • A final strength 90 psi (ASTM D-1621)

6
Installation
  • Requires open paths for pressure release
  • This can be minimize by injecting in small shots.
  • The foam will begin to expand in under a minute.
