High Performance Fiber Reinforced Concrete for Pavements
Şengün, Emin; Alam, Burhan; Yaman, İsmail Özgür (2016-09-21)
The addition of fibers has allowed concrete to take a role in the field of ductile materials. In this field, pavements were always a challenge and a success for concrete. To be a strong rival to asphalt, concrete needs to be more flexible, which is possible by the use of fibers. However, for this concrete pavement to be able to survive and last as long as possible it needs to be a high performance one. The shy use of concrete pavements in Turkey shows the need for further researches on the local base to all...
High performance structural lightweight concrete utilizing natural perlite aggregate and perlite powder
Eser, Hasan; Turanlı, Lütfullah; Department of Civil Engineering (2014)
Structural Lightweight Concrete is generally made by using artificial lightweight aggregates such as expanded clay, shale and slate. However, rapidly increasing fuel prices in recent decades and corresponding increase in the production costs of these aggregates have renewed the interest in natural lightweight aggregates such as pumice, scoria, rhyolite and perlite. This study investigates the mechanical properties and durability characteristics of high-performance lightweight concretes utilizing natural per...
High Strength Copper Alloys for Extreme Temperature Conditions
Dincer, Onur; Pehlivanoglu, Kaan M; Dericioğlu, Arcan Fehmi (null; 2016-11-25)
Having high thermal conductivity and high strength copper alloys can be used as structural material in various applications such as thrust chamber of liquid rocket engine, nuclear reactor and electromechanical launch systems requiring high heat flux transfer. To improve mechanical properties without losing the thermal conductivity precipitation and dispersion strengthening mechanism can be applied. In this paper some selected high strength copper alloys used under extreme temperature environments were discu...
High strength bioresorbable bone plates: preparation, mechanical properties and in vitro analysis
Hasırcı, Vasıf Nejat; Bondre, SP; Gresser, JD; Trantolo, DJ; Wise, DL (2000-01-01)
Biodegradable bone plates were prepared as semi-interpenetrating networks (SIPN) of crosslinked polypropylene fumarate (PPF) within a host matrix of either poly(lactide-co-glycolide) - 85 : 15 (PLGA) or poly(l-lactide-co-d,l-lactide) - 70 : 30 (PLA) using N-vinylpyrrolidone (NVP), ethylene glycol dimethacrylate (EGDMA), 2-hydroxyethyl methacrylate (HEMA), and methyl methacrylate (MMA) as crosslinking agents. Hydroxyapatite (HAP), an inorganic filler material, was used to further augment mechanical strength....
