Key features of numerical models for the FE-simulation of deep tunnel advance by the NATM
Underground SpaceIn the present work, important aspects of time-dependent nonlinear 3D finite element (FE) models for deep tunnel advance by the New Austrian Tunneling Method (NATM), characterized by repeated sequences of excavation, securing, and idle periods, are ...

Lightweight Aggregate Concrete: Strength Analysis
Current Journal of Applied Science and Technology, 2022 The lightweight concrete (LWC) has been successfully employed, by the ancient Romans and its popularity has grown for its reduced density and higher thermal insulation capabilities. Compared to ordinary mix concrete (OMC), LWC can substantially lessen the dead load of high-rise structures. The density of LWC is comparatively low i.e. 300 to 1850 kg/m3,
