As part of a previous study, WisDOT examined the scaling durability of ordinary Portland cement (OPC) concrete, and 30% and 50% grade 120 slag cement concretes when subject to a variety of curing regimes including wet curing, dry curing, poly-alphamethylstyrene curing compound, wax-based curing compound and other methods designed to limit carbonation for 60 cycles of ASTM C672 testing. Evaluations were conducted with northern igneous aggregates as well as southern limestone aggregates combined with different brands of Type I/II cement. The proposed research plan builds on prior experience in the area of concrete durability. This research will expand on previous results by including Grade 100 slag cement and fly ash to the extensive data already gathered.
