Work Item
ASTM WK86741
Revision of C1012/C1012M-18b Standard Test Method for Length Change of Hydraulic-Cement Mortars Exposed to a Sulfate Solution
Rationale
The current curing regime for the bars prior to submersion of bars in the sulfate solution can lead to a high level of variability. Additionally the curing regime does not allow for a significant amount of reaction of slower reacting cementitious materials (i.e. fly ash, slag, natural pozzolans) which can impact the permeability.
