BACKGROUND AND PURPOSE Locally compacting the mesh of a flow diverter by a dynamic push-pull technique can accelerate intracranial aneurysm healing. We asked how this deployment strategy compares with overlapping 2 flow diverters for aneurysmal flow reduction. MATERIALS AND METHODS Using a high-fidelity virtual stent placement method, we simulated 3 flow-diverter strategies (single noncompact...

A Lagrangian particle-based method, the smooth particle hydrodynamics, is used to model the flow of ultra-highperformance, self-compacting concretes containing short steel fibres which behave like a non-Newtonian fluid described by a Bingham-type constitutive model. An incompressible smooth particle hydrodynamics method is used to simulate the flow after the kink in the shear stress against the...

Self-compacting concrete (SCC) is one of the most significant advances in concrete technology in the last two decades. SCC was developed to ensure adequate compaction through self-consolidation and facilitate placement of concrete in structures with congested reinforcement and in restricted areas. Marble Sludge Powder (MSP) can be used as filler and helps to reduce the total voids content in co...

The production of tailor made high strength and high performance concrete are made by incorporating silica fume into the normal concrete and it is a routine one in the present days. The mix proportioning is intricate and the design parameters are increased due to the incorporation of silica fume in conventional concrete. The aim of this paper is to look into the different mechanical properties ...

Self-compacting concrete (SCC) developed in Japan in the late 80s has enabled the construction industry to reduce demand on the resources, improve the work condition and also reduce the impact of environment by elimination of the need for compaction. Fuzzy logic (FL) approaches has recently been used to model some of the human activities in many areas of civil engineering applications. Especial...

Self compacting concrete (SCC), developed by Hajime Okamura, has proved to be an excellent concrete in terms of its compactability, flowability and durability apart from strength studies have proved that the effienciency of the SCC can be further increased by introduction of fibres like steel fibres, glass fibres etc. further enhances their toughness, tensile strength, resistance to crack propa...

The utilization of recycled aggregates and various industrial by-products is considered a sustainable strategy in the concrete industry. In this study, effect maximum size coarse aggregate cementitious binder content on fresh hardened properties self-compacting was investigated. Self-compacting concretes with sizes 9.5 mm, 12.5 19 mm were prepared at water-to-binder ratios 0.39, 0.42, 0.45, res...
