  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
