Clustering of air voids around aggregates in air entrained concrete
(2007-05)
Recent research reports have suggested that one of the potential causes of low compressive strengths in air-entrained concrete is the clustering of air voids around the aggregates. The phenomenon of clustering of air voids ...
Laboratory and field investigations on the use of lithium nitrate to prevent or mitigate alkali-silica reaction
(2007-05)
This research project, funded by the Federal Highway Administration (FHWA Project DTFH61-02-C-0097), focuses mainly on alkali-silica reaction (ASR) studies and ways to mitigate the effects of alkali-silica reaction in fresh ...
The prediction of coarse aggregate performance by micro-Deval and other soundness, strength, and intrinsic particle property tests
(2006-05)
This research project concentrated on determining whether or not a correlation existed between laboratory aggregate tests and observed aggregate field performance. For this purpose, aggregate samples were collected from ...
