**Test Duration:** 72 Hours

**Standard:** Concrete without the use of DAY1. Significant amount of Corona development with some pop-outs is due to the increased amount of free alkalis to break down the reactive aggregate.

**500:** Concrete finished with DAY1 used at a rate of 500 sf per gallon. The colloidal silica in the DAY1 reduces the tendency for polymerization and expansion of the ASR gel. This is possible through chemical binding / stabilization of the alkalis that would propagate ASR.

**250:** Concrete finished with DAY1 used at a rate of 250 sf per gallon. The phenomenon is enhanced with a higher dosage of the DAY1 that almost eliminates the near surface ASR.
