    Computed tomography (CT) is a nondestructive technique, based on absorbing X-rays, that permits the visualisation of the internal microstructure of material. The field of application is very wide. This is a well-known technology in medicine, because of its enormous advantages, but it is also very useful in other fields. Computed tomography is used in palaeontology to study the internal Cited by: 7. This research evaluated the suitability of stone dust in the design and production of High Perfor-mance Concrete (HPC). HPC mix was designed, tested, costed and a comparison of concrete classes used in the market (Cl 30 and 35) done using Cost Benefit Analysis (CBA). The cost benefit was analyzed using Internal Rate of Return (IRR) and Net Present Value (NPV).Cited by: 2.

      The most important technical polyesters are presented in detailed chapters, homogeneous polymers as well as copolymers, blends and high-performance reinforced polyester materials are discussed. This book is directed to chemists, physicists and engineers working in research, development and application of polymers. Description. This title provides a comprehensive overview of all aspects of the mechanical behavior of concrete, including such features as its elastoplasticity, its compressive and tensile strength, its behavior over time (including creep and shrinkage, cracking and fatigue) as well as modeling techniques and its response to various stimuli.

    Ultrahigh performance concrete (UHPC) realized distinctly high mechanical, impermeability, and durability characteristics by reducing the size and content of capillary pore, refining the microstructure of cement hydrates, and effectively using fiber reinforcement. The dense and fine microstructure of UHPC favor its potential to effectively disperse and interact with nanomaterials, which could Cited by: fundamental needs to achieve high performance concrete. To do so, mix should be such it is easy to vibrate and it is fluid enough to pass through congested reinforcement. HPC possesses three characteristics: high strength, high durability and high workability 2. A minimum slump of mm is therefore preferred3. Durability is.

Naaman University of Michigan Ann Arbor, Michigan Strategic Highway Research Program. The variation of free thermal strains with temperature was determined for 4 laboratory concretes and 4 industrial concretes.

All the concretes show almost the same behavior up to °C. The free thermal strain of concrete above °C decreases when paste volume or W/B ratio by: The effects of high-temperature exposure on the chemical composition and mechanical behavior of conventional concrete are well known.

However, the ever-changing world of structural engineering challenges the performance of traditional materials and encourages the development of new solutions in concrete engineering, whose fire performance needs.

Mechanical Characteristics of High Performance Fibre Reinforced Concretes at Elevated Temperatures By K. Sideris, P. Manita, A. Papageorgiou and E.

In recent years, appeared very high performance concretes which are the result of a more and more scientific rationalization. The use of superplasticizers, and more recently of ultrafine particles such as silica fume, has significantly minimized the amount of mixing water in concrete. Studies on the effects of high temperature on the mechanical properties of HSC could trace back to as early as the s.

The fracture energy, which is a measurement of ductility, can re J/m2 forRPC, as compared to to J/m2 for ordinary concretes. Fracture energy depends on the volume of fibers added to the concrete. The optimum content is between 2 and 3% by by: Previously, classical nanoindentation techniques have been employed to study the local mechanical behavior of cement-based materials, such as the micro-mechanisms of creep in C–S–H phases or the interface transition zone in normal concretes reinforced by an optimal system of polymeric by: mechanical properties of high performance concretes mixtures when exposed to high temperature up to oC.

The results of an experimental investigation in to the effects of high temperature on the residual compressive and tensile strengths for high performance concretes made with ordinary Portland cement are presented.

Various types of ultra-high-performance fiber-reinforced concrete (UHPFRC) have been developed by researchers worldwide [1][2][3][4] to overcome several drawbacks of ordinary concrete, such as low.
