Concrete as a Hierarchical Structural Composite Material
摘要
A multiscale modeling methodology that relates the nanostructure of concrete to its micro and macro properties is presented. This work attempts to establish a framework for understanding the relations among chemical composition, microstructure morphology, and the macroscale mechanical properties of concrete constituents. The simulation is based on four levels of a hierarchal structural model, starting from the molecular dynamics simulation of hydrated cement solid nanoparticles (e.g., C{S{H, and calcium hydroxide), all the way up to concrete. To validate the theoretical model, a nondestructive testing technique, resonant ultrasound spectroscopy (RUS), is used to measure the elastic constants of hydrated cement paste. The results showed good agreement between theoretically predicted and experimentally measured properties.
