1
Controlled Low Strength Material (CLSM) aka
Flowable Fill
  • Presented by
  • Daniel Garza

2
Composition of Concrete Fill
  • Cement
  • Sand
  • Water
  • Air-Entraining Additive
  • Elastizell Engineered Fill
  • Darafill

3
Property Comparisons
Property CLSM Type II Concrete
Cast Density 75-90 pcf 150 pcf
28-day compressive strength 90 psi 3000 psi
Slump unattainable 3 - 4
4
Specific Job Use
  • Corpus Christi Seawall Project

5
Mixing Procedure
  • Admixture added at site

6
Placement Procedure
  • Longitudinally-cut pipe used as troughs

7
Placement Procedure
  • Flow of concrete similar to water

8
Voids Before Placement
  • Bulkheading required to contain flow

9
Voids After Placement
  • Density low enough for hand excavation

10
Finished Section
  • Used as formwork for concrete placement
