Abstract: The ability of in-place pervious concretes to effectively drain storm water runoff gradually reduces as it becomes clogged due to the ingress of fine particles into its pore structure. This study systematically investigates ...

Abstract: A three-dimensional (3D) discrete element method (DEM)-based numerical model is used to simulate the macromechanical response of sand strengthened using microbially induced carbonate precipitation (MICP) under undrained ...

Abstract: Dwindling energy resources and associated environmental costs have resulted in a serious need to design and construct energy-efficient buildings. One of the strategies to develop energy efficient structural materials is ...

Abstract: This paper presents fracture responses of alkali-activated slag (AAS) mortars with up to 30% (by volume) of slag being replaced by waste iron powder that contains a significant fraction of elongated iron particles. The ...

Abstract: This paper simulates fracture in notched mortar beams under three-point bending using an extended finite-element method (XFEM) and peridynamics. A three-phase microstructure (i.e., cement paste, aggregates, and ...
