Presentation Transcript

  1. Presented by: Daniel Garza Controlled Low Strength Material (CLSM)aka ‘Flowable Fill’

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

  3. Property Comparisons

  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
