Welcome to ARS Companies | Exceptional …
ARS employs the Hydrated Lime Slurry method which has numerous benefits over dry lime including the elimination of lime dust as well as the guarantee of full lime hydration. LTS/FA and LTS/CTS: Typically if there is less than 7% clay present a lime/fly ash combination may be necessary. Typically 1-3:1 Ratio of lime to fly ash is adequate.

The ratio η / L v, in which L v is adjusted by an exponent (in this case 0.12 for all soil–fly ash–lime mixtures studied), is shown to be a good parameter in the evaluation of the UCS of the soil studied (UCS varies nonlinearly with η / L v in the case of fly ash–lime addition). Finally, it was found that a unique correlation controls ...
