Sika® Lightcrete Flow-Air

Flowable Fill Performance Admixture

The addition of Sika® Lightcrete Flow-Air generates high, stable air contents while
significantly reducing water requirements in CDF. When used as recommended, Sika
Lightcrete Flow-Air enhances the performance of CDF as follows:

  • Increases flowability with a water reduction as high as 50%.
  • Reduces segregation.
  • Controls strength development with stable air contents of 20% to 35%.
  • Produces consistent performance from the plant to the jobsite.
  • Increases the yield of materials up to 35%.
  • Yields wet densities in the range of 1450 to 1800 kg/m3 consistently.
  • Generates extremely high stable air contents.
  • Provides comparable or faster setting times compared to conventional CDF.
  • Aids pumpability and reduces segregation from pumping.
  • Reduces shrinkage as a result of lower cement and water contents.

Usage

Sika® Lightcrete Flow-Air is primarily used in control density fill (CDF) cementitious mixtures to lower densities and control compressive strength where applications may call for future excavations. Sika® Lightcrete Flow-Air is designed for use with cement and pozzolans, such as fly ash and slag, to produce flowable fill. Sika® Lightcrete Flow-Air is carefully formulated and subjected to stringent quality control in order to guarantee superior results in both the plastic and hardened control density fill (CDF).
