The Particle-Matrix model: limitations and further improvements needed
Cepuritis, Rolands; Jacobsen, Stefan; Spangenberg, Jon (Journal article; Peer reviewed, 2017)According to the Particle-Matrix Model (PMM) philosophy, the workability of concrete depends on the properties of two phases and the volumetric ratio between them: the fluid matrix phase (≤ 0.125 mm) and the solid particle ... -
Three dimensional shape analysis of concrete aggregate fines produced by VSI crushing
Cepuritis, Rolands; Garboczi, Edward J.; Jacobsen, Stefan (Journal article; Peer reviewed, 2016)We studied the 3-D shape of concrete aggregate fines with particle sizes between 3 µm and 250 µm produced by high-speed vertical shaft impact (VSI) crushing of rock types from 10 different quarries representing a wide range ...
