FRACTURE MECHANICS OF CONCRETE AND ROCK This book offers engineers a unique opportunity to learn, frominternationally recognized leaders in their field, about the latesttheoretical advances in fracture mechanics in concrete, reinforcedconcrete structures, and rock. At the same time, it functions as asuperb, graduate-level introduction to fracture mechanics conceptsand analytical techniques. Reviews, in depth, the basic theory behind fracture mechanics * Covers the application of fracture mechanics to compressionfailure, creep, fatigue, torsion, and other advanced topics * Extremely well researched, applies experimental evidence ofdamage to a wide range of design cases * Supplies all relevant...
The International Symposium in Brittle Matrix Composites October 13-15, 2003 covers a wide spectrum of topics including cement based composites, ceramic composites and brittle polymer matrix composites. In the papers various topics and issues are considered such as: analytical and numerical studies related to the design of composites, prediction of behaviour and verification of strength and stability, testing methods, manufacturing processes and repair, environmental effects and durability assessment. The present volume of 55 papers proves that there are still many problems in the field of brittle matrix composites deserving theoretical and experimental investigations and that new solutions to these problems are needed for practical application in civil engineering, industrial structures, machinery and other domains.
Wann tritt Agglomeration auf, wie lässt sie sich vermeiden und in welchen Fällen kann man sie sinnvoll nutzen? Ausführliche Antworten auf diese Fragen gibt Ihnen der Autor dieses Bandes, Fachmann und Berater mit langjähriger Industrieerfahrung. Neben den traditionellen Anwendungsgebieten der Agglomeration (unter anderem pharmazeutische Industrie, Nahrungs- und Futtermittelherstellung, Düngerproduktion und Agrochemie, Baustoffindustrie, Bergbau und Metallverarbeitung) werden auch aktuellste Entwicklungen, etwa im Bereich der Nanotechnologie, besprochen.
Emphazises the most recent advances in fracture mechanics as specifically applied to steel bar reinforced concrete. Extensive expert opinions in four selected areas: size effects; anchorage and bond; minimum reinforcement for elements in flexure; and shear resistance. Logically addresses themes and demonstrate the unique ability of fracture mechanics to capture all the experimentally observed characteristics.
The freeze-thaw resistance of concretes was studied. Nine concrete mixes, made with five cements and cement-Class C fly ash combinations, were exposed to freeze-thaw cycling following 110 to 222 days of moist curing. Prior to the freeze-thaw cycling, the specimens were examined by a low-vacuum scanning electron microscope (SEN) for their microstructure. The influcence of a wet/dry treatment was also studied. Infilling of ettringite in entrained air voids was observed in the concretes tested. The extent of the infilling depends on the period of moist curing as well as the wet/dry treatment. The concretes with 15% Class C fly ash replacement show more infilling in their air voids. It was found...
