Description:

Aggregates that record high water uptake during the Iowa Pore Index test, Michigan Test Method MTM 128, typically produce high expansions in concrete when tested for freezing and thawing according to Michigan Test Method MTM 115, using vacuum-saturation pre-treatment. Absorption values obtained during Iowa Pore Index tests conducted on absorbent and dense aggregates were used to generate graphical plots. Highly absorbent aggregates that produce high expansions in concrete when subjected to freeze-thaw tests were shown to produce curves that followed power correlations, whereas dense aggregates that produce low expansions in the freeze-thaw test were shown to produce curves that followed linear correlations.
