Concrete Mixtures with High Microfines
Quiroga, Pedro Nel; Ahn, Namshik; fowler, david (American Concrete InstituteEstados Unidos, 2006)Two projects were performed to evaluate the effect of the amount and type of microfines (material passing the No. 200 sieve), as well as the effect of shape, texture, and grading of aggregates on concrete behavior. In the ... -
Three-dimensional shape analysis of coarse aggregates: New techniques for and preliminary results on several different coarse aggregates and reference rocks
Quiroga, Pedro Nel; fowler, david; Erdogan, Sinan; Saleh, H.A.; Livingston, Richard; Garboczi, Edward J.; Ketcham, Peter M.; Hagedorn, John G.; Satterfield, Steven G. (ElSevierEstados Unidos, 2006)The shape of aggregates used in concrete is an important parameter that helps determine many concrete properties, especially the rheology of fresh concrete and early-age mechanical properties. This paper discusses the ...
