To compare the ability of the cartilage precursor cells derived from allogenic and autologous bone marrow mesenchymal stem cells (MSCs) respectively seeded onto “two-phase” allogeneic bone matrix gelatin (BMG) for constructing tissue engineered cartilage in the repair of articular cartilage defects and to observe the repairing efficacy of the two composites for providing the basis for the clini...

An extrusion process especially designed for extrusion of pipes made from fiber reinforced cementitious materials has been developed at Department of Structural Engineering and Materials at the Technical University of Denmark. Engineered Cementitious Composite (ECC) materials have been developed in recent years at Department of Civil and Envirionmental Engineering, University of Michigan. These...

This paper builds on previous self-healing engineered cementitious composites (ECC) research by allowing ECC to heal outdoors, in the natural environment, under random and sometimes extreme environmental conditions. Development of an ECC material that can heal itself in the natural environment could lower infrastructure maintenance costs and allow for more sustainable development in the future ...

This paper presents an experimental study on the fundamental performances of a sprayed engineered cementitious composite (ECC) in repair systems. ECC serving as a repair material has been expected to be highly effective in providing durable repaired structures because of the tight crack width control and high delamination resistance. For this study, a polyvinyl alcohol (PVA) fiber-reinforced EC...

This paper presents an experimental study on the monotonic and fatigue behavior of a link slab designed for a durable concrete bridge deck system. The requirements on the link slab in terms of material properties, dimensions, and reinforcement detailing are considered. Special focus is placed on the deflection capacity of the link slab and its fatigue performance. This paper discusses the choic...

In the present work, important subject of improvement strength and durability future generation smart nano-engineered cementitious composites is evoked through incorporation another kind nanomaterial like fullerene buckyballs (C60). This research dedicated to analysis - at nanoscale processus embedding C60 nanomaterials in calcium silicate hydrates (C–S–H). Using molecular dynamics simulations,...

Metal matrix composite (MMC) is engineered combination of the metal (matrix) and hard particle (reinforcement) to get tailored properties. MMCs are either in use or prototyping for the space shuttle, commercial airliners, electronic substrates, automobiles, golf clubs, and a variety of other applications.In this study, carbon nanotubes (CNTs) reinforced aluminum MMCs were synthesized by DPDS fo...
