Expanded Shale Used as an Admixture for Sand-Gravel Aggregate Concrete
Certain Kansas sand-gravels when used for concrete create a cement-aggregate reaction. This reaction is exhibited in the form of expansion, cracking and flexural strength loss. This study dealt with the expansion factor. Previously limestone aggregate had been added to the sand-gravel mixes to control the cement aggregate reaction. This study explored the use of lightweight expanded shale aggregate as a sweetener instead of the limestone. Both the field study and the laboratory testing found that the lightweight aggregate sweetened concrete expanded slightly more than the limestone sweetened concrete. Also, laboratory tests showed that the lightweight aggregate was more susceptible to cement brand than the limestone. (Author)
