  2. 1. Characterization, Activation and Reactivity of Natural Pozzolans for Use as Supplementary Cementitious Materials

    Author : Amrita Hazarika; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reactivity; Volcanic Materials.; Clays; Pozzolans; Activation; SCMs;

    Abstract : Supplementary cementitious materials (SCMs) represent one of the most practicable ways to reduce the negative environmental impact of cement. Natural pozzolans like clays and volcanic materials (VMs) offer promising alternatives to industrial by-products such as blast furnace slags and fly ashes, whose availability cannot meet the growing demand for SCMs globally.

    Abstract : Coronary artery disease and chronic pain are serious health issues that cause severe discomfort and suffering in society today. Antithrombotic agents and highly potent analgesics play a critical role in improving the recovery process for patients being treated for these diseases. READ MORE

  5. 3. Molecular Order and Dynamics in Nanostructured Materials by Solid-State NMR

    Author : Boris Kharkov; Sergey Dvinskikh; Steven Brown; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; mesoporous materials; organic-inorganic nanocomposites; surfactants; liquid crystals; MCM-41; clays; conformational dynamics; solid-state NMR; local field spectroscopy; dipolar coupling; dipolar recoupling; spin decoupling.; Kemi; Chemistry;

    Abstract : Organic-inorganic nanostructured composites are nowadays integrated in the field of material science and technology. They are used as advanced materials directly or as precursors to novel composites with potential applications in optics, mechanics, energy, catalysis and medicine. READ MORE

  7. 5. Long Term Settlements in Soft Clays

    Author : Peter Claesson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; calculation model; settlements; stress-strain-strain rate; consolidation; deep layers; case records; creep; lightly overconsolidated soft clay;

    Abstract : When structures are founded on deep layers of lightly overconsolidated, soft clay large settlement often occur during a long period of time after completion of the structure. Therefore it is of major importance to be able to calculate and predict the expected settlements with a satisfactory degree of accuracy, as this has a great impact on the design of the foundation and the possible need for soil improvements.
