Gerrard – Near-Surface Aggregate Reactivity. (NSAR)
NSAR Coined by Peter Craig
ASR in the surface of the concrete induced by moisture sensitive floors

C33 doesn’t screen this out, it occurs with 1% (Pierre Shale – very deleterious – 100ma amorphous opaline shale – zooplankton)
• Reaction usually only happens in summer
• Surface prep, other defects – bruising, debris, steel shot…osmotic pressure works on the defect. The shale continues to react, even in 40 year-old floors.
• This is not unique…will see many of these in Minnesota
• They see these in Iowa, but only in sands and they tell them to flush the surface in order to flush away the alkalis.
