Research Topics

Both computational modeling and experimental measurements are crucial to understand, predict, and improve concrete performance. The cross-scale research focuses on the computational and experimental measurement of cement concrete, asphalt concrete, geomaterial, steel rebar and polymer, including simulation of microstructural development and prediction of mechanical properties of them. "Microstructure" ranges from nanometer to meter length scales, while mechanical properties include pressure-driven fluid transport, fracture, rheology, and durability. Available experimental methods including neutron scattering, electron microscopy, and various X-radiation probes like diffraction and tomography are used to inform and validate models.
