Moisturetransport in aerated concrete- and brickfacades : A study of how moisture behave and transports in a facade of two different materials with different porosities (English)
Abstract [sv]

I dagsläget finns en stor mängd byggnader i Sverige där fasaden består av puts direkt anliggande mot antingen lättbetong eller tegel. Dessa fasader kan skapa problem för brukaren p.g.a. fukttransport via putsen direkt in i konstruktionen. Problemen som kan uppstå som följd av dessa konstruktioner är inte bara estetiska utan kan även påverka inomhusmiljön. Syftet med detta arbete var att undersöka om det gick att med ny teknik visa de resultat som framkommit från erfarenheter från praktiskt arbete samt undersöka hur en renovering påverkar de fasader som består av puts direkt mot lättbetong eller tegel. Arbetet har utförts med hjälp av simuleringsprogrammet Wufi Pro för att sedan analyserats med hänsyn till fukttransporter och vatteninnehåll. Resultaten som framkommit påvisar en förhöjd risk för problem med de ursprungliga fasaderna samt slutsatsen att en renovering enligt ett av de två förslagen är att föredra.

Abstract [en]

Today there’s a great deal of buildings in Sweden where the facade is constructed by plaster directly connected to either aerated concrete or masonry brick. These facades could create problems for the user on accord of the moisture transport via the plaster directly into the construction. The problems that could follow these types of facades aren’t just esthetical but could also affect the indoor environment. The purpose with this study was to examine if it would be possible using today’s technology to show the results coming from past experiences by practical work, and at the same time examine how a remodel affects the facades that consists of plaster directly on aerated concrete or masonry brick. The work has been conducted with the simulation program Wufi Pro, later to be analyzed  according to moisture transport and water content. The results that came from this has shown an increased risk for problems with the original facades and at the same time that a remodel according to one of the two proposed remodel ways to prefer.
