  1. 1. Rheology of building materials

    University dissertation from National Swedish Building Research / Statens Institut för byggnadsforskning (BFR)

    Author : Anders Nielsen; [1972]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; rheology; building materials; long-term deformations moisture; temperature ; creep; modulus of elasticity; reologi; byggnadsmaterial; långtidsdeformation fukt; temperatur ; krypning; elasticitetsmodul;

    Abstract : This document is a survey of the longterm deformations of building materials. A description of these deformations, common to all the materials, is given. The following materials are considered: concrete, cellular concrete, wood, fìberboard, partícle board, plywood, and to a lesser extent polymers and aluminium. READ MORE

  2. 2. Jamming and Soft-Core Rheology

    University dissertation from Umeå : Umeå Universitet

    Author : Daniel Vågberg; Umeå universitet.; [2013]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; jamming; rheology; soft matter; granular material; SLLOD; critical point; critical scaling;

    Abstract : Many different physical systems, such as granular materials, colloids, foams and emulsions exhibit a jamming transition where the system changes from a liquid-like flowing state to a solid jammed state as the packing fraction increases. These systems are often modeled using soft-core particles with repulsive contact forces. READ MORE

  3. 3. Hydrophobically Modified Polymers. Rheology and Molecular Associations

    University dissertation from Physical Chemistry 1, Lund University

    Author : Leif Karlson; Lunds universitet.; Lund University.; [2002]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; polymer self diffusion; Physical chemistry; Fysikalisk kemi; rheology; hydrophobically modified polyethylene glycol; hydrophobically modified ethyl hydroxyethyl cellulose; cyclodextrin; hydrophobically modified polymer; associative thickener;

    Abstract : Popular Abstract in Swedish Vattenbaserad målarfärg är ett exempel på en vattenlösning som måste förtjockas för att den skall uppföra sig som vi vill. I en färg med för låg viskositet sjunker alla partiklar snabbt till botten på burken och när man målar kan man bara ta lite färg i penseln om inte färgen skall droppa. READ MORE

  4. 4. Rheology of cement grout  Ultrasound based in-line measurement technique and grouting design parameters

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Mashuqur Rahman; KTH.; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; grouting; grouting design; cement grout; Bingham number; shear rate; plug flow; thixotropy; yield stress; in-line rheology; UVP PD; Flow-Viz; viscosity bifurcation; aging; off-line rheometry; pump characteristics; Civil and Architectural Engineering; Byggvetenskap;

    Abstract : Grouting is performed in order to decrease the permeability and increase the stiffness of the material, especially soil and rock. For tunnelling and underground constructions, permeation grouting is done where cement based materials are pumped inside drilled boreholes under a constant pressure, higher than the ground water pressure.

  5. 5. Rheology and UV-curing of a star-branched polyester

    University dissertation from Institutionen för polymerteknologi

    Author : Hans Claesson; KTH.; [2001]
    Keywords : Powder coating; UV-curing; star-polymer; gel point; alipahtic polyester; rheology; dendritic;

    Abstract : The use of powder coatings has increased steadily over thelast few decades. Their popularity is due to a number of majoradvantages they offer when compared to solvent-borne systems.Near zero VOC-content, reduced energy consumption and near 100%utilisation of the material are some of the advantages.
