This study examined the types of microfines in aggregates found in northern Wisconsin and their influence on concrete prepared according to Wisconsin Department of Transportation (WisDOT) specifications. Aggregates were ...

The water-cementitious material ratio (w-cm) is defined as the ratio by mass of free water to cementitious material in a concrete mix. The microwave oven method (AASHTO provisional standard TP23-93) and the nuclear ...

This research examined the impact of cement replacements with Grade 100 ground granulated blast furnace slag (GGBFS) on portland cement concrete performance. GGBFS was used to replace 0%, 30% and 50% of cement in a series ...

This report documents the investigation of a 15-mile segment of doweled plain jointed concrete pavement located on Interstate 90/94 in Juneau and Sauk Counties in the State of Wisconsin. This section has experienced a ...

The WisDOT sponsored study entitled: "Effects of Aggregate Coatings and Films on Concrete Performance", ID: 0092-00-07, found that clay coatings showed a deleterious impact in concrete compared with other microfine mineralogy ...

This research examined the properties of concrete containing grade 120 slag cement at replacement levels of 0%, 30%, and 50%. The primary concrete properties studied were compressive strength, split-tensile strength, and ...

Coarse aggregates containing surface coatings were collected throughout Wisconsin and characterized to determine composition. Based on the results of these tests, a subset of the sample aggregates was selected to further ...
