Detecting deleterious fine particles in concrete aggregates and defining their impact
(Wisconsin Highway Research Program, 2010-10)
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 ...
Field measurement of water-cement ratio for Portland cement concrete. Phase II, Field evaluation and development
(Wisconsin Highway Research Program, 2002-06)
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 ...
Effects of ground granulated blast furnace slag in Portland cement concrete
(Wisconsin Highway Research Program, 2005-02)
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 ...
Analysis of concrete pavement joints to predict the onset of distress
(Wisconsin Highway Research Program, 2007-10)
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 ...
Expanded study on the effects of aggregate coating and films on concrete performance
(Wisconsin Highway Research Program, 2007-09)
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 ...
Effects of ground granulated blast furnace slag in Portland cement concrete : expanded study
(Wisconsin Highway Research Program, 2007-06)
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 ...
Effects of aggregate coatings and films on concrete performance
(Wisconsin Highway Research Program, 2003-04)
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 ...
