Electrically conductive roller-compacted concrete (ERCC) is a novel functional material, which can solve the problems of low efficiency artificial snow removal and deicing on expressway airport runway difficulty in temperature control dam engineering structures. In this study, we designed ERCC conducted an experimental study numerical simulations ERCC. The improvement mechanism su...

To represent the structural behavior of self-compacted concrete filled steel tube composite columns under axial compression loading after high temperatures exposure, a nonlinear three dimensional finite element analysis model has been achieved to analyze these using ANSYS R-15 software. An eight-node solid brick (Solid65) is used concrete, while four-node isoparametric shell (Shell63) for analy...

M. Naor (Ed.): TCC 2004, LCNS 2951, pages 336 352, February 2004. c © Springer-Verlag Berlin Heidelberg 2004. Abstract. We consider compositional properties of reactive systems that are secure in a cryptographic sense. We follow the well-known simulatability approach of modern cryptography, i.e., the specification is an ideal system and a real system should in some sense simulate this ideal one...

:‘)ii$ Machine piling of slash and brush after harvest is commonly practiced when establishing new conifer plantations. However, it can result in increased soil bulk density, decreased soil macroporosity, and increased soil strength, thus reducing conifer root development and above-ground growth (Froehlich 1979, Sands and Bowen 1978). Because natural recovery of soil from compaction is slow, wa...

BACKGROUND We used cardiovascular magnetic resonance (CMR) to study normal left ventricular (LV) trabeculation as a basis for differentiation from pathological noncompaction. METHODS AND RESULTS The apparent end-diastolic (ED) and end-systolic (ES) thicknesses and thickening of trabeculated and compacted myocardial layers were measured in 120 volunteers using a consistent selection of basal, ...

Pervious concrete is one of the emerging sustainable materials that has recently gained attention many researchers. The importance pervious mainly depends on its application and a modern integrated approach in which it employed to reduce effects flooding. main goal this experimental analysis study significance aggregate size degree compaction mechanical hydraulic properties concrete.
