  1. 1. Mould on building materials - A calorimetric study of fungal activity as a function of environmental factors

    Detta är en avhandling från Division of Building Materials, LTH, Lund University

    Författare :Yujing Li; Lund University.; Lunds universitet.; [2007]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; materiallära; byggnadsteknik; building construction; fungal activity; temperature; relative humidity; building; image analysis; indoor environment; wood; materialteknik; material technology; mould; calorimetry; isothermal calorimeter;

    Sammanfattning : Mould problems in buildings have become a growing concern during the past decades. The growth of mould fungi indoors deteriorates air quality, influences human health and causes economical losses. Preventing mould growth from occurring is a more cost effective option than cleaning and renovation of buildings with mould problems. LÄS MER

  4. 4. Rheology of building materials

    Detta är en avhandling från National Swedish Building Research / Statens Institut för byggnadsforskning (BFR)

    Författare :Anders Nielsen; [1972]
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  5. 5. Transport and sorption phenomena in concrete and other porous media

    Detta är en avhandling från Division of Building Materials, LTH, Lund University

    Författare :Björn Johannesson; Lund University.; Lunds universitet.; [2000]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Byggteknik; Civil engineering; Durability; Sorption; Capillary suction; Diffusion; Convection; Concrete; Byggnadsteknik; Mixture Theory; Building construction;

    Sammanfattning : The work presented in this thesis is mainly focused on transport processes involved in service life predictions of concrete. Two papers and three reports deal with ion transport in pore solution of concrete. LÄS MER
