2. 1. Traditional lime mortar and plaster : Reconstruction with emphasis on durability

   Author : Kristin Balksten; Tor Broström; Britt-Marie Steenari; Thorborg Konow von; Chalmers Tekniska Högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; lime plaster; lime mortar; masonry; craftsmanship; pore structure; frost resistance; historic mortar; Conservation HGO ; Kulturvård HGO ;

   Abstract : Lime mortar and plaster have been investigated with the aim to improve the knowledge on how to make them as durable as before the cement technology was developed. The background was the durability problems experienced for newly produced lime plaster on the medieval churches on the island of Gotland, Sweden. READ MORE

5. 3. Characterisation and Consolidation of Historical Lime Mortars in Cultural Heritage Buildings and Associated Structures in East Africa

   Author : Athuman M. K. Ngoma; Jonas Holmgren; Jan Erik Lindqvist; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; East Africa; Stone Town; historical building; mortar; deterioration; consolidation; calcium hydroxide solution; Building engineering; Byggnadsteknik;

   Abstract : For the period of several centuries, the influence of several distinct cultures produced rich and diverse cultural heritage that we see today in East Africa countries. The most tangible remains of these heritages are stone built buildings and structures including, palaces, mosques, residential houses and tombs. READ MORE

6. 4. Moisture permeability of mature concrete, cement mortar and cement paste

   Author : Göran Hedenblad; Avdelningen för Byggnadsmaterial; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; moisture transport; cement paste; moisture permeability; concrete; moisture flow; cement mortar;

   Abstract : Moisture permeability tests were performed on specimens of concrete, cement mortar and cement paste with the bottom side in water or in moist air and the upper side in a relative humidity of 33 %. The distribution of the relative humidity within the specimen was measured, at stationary conditions, as well as the amount of water which pass through the specimen. READ MORE

7. 5. Structure of Hardened Cement-Fly Ash Systems and Their Related Properties

   Author : Aimin Xu; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; water vapour sorption isotherms; thermogravity analysis; mortar; scanning electron microscopy; differential thermal analysis; X-ray diffraction analysis; fly ash; pore structure; microstructure; cement paste;

   Abstract : The influence of fly ash on the pore structure and microstructure of cement paste and mortar has been investigated. The methods applied include water vapour sorption isotherms, scanning electron microscopy, X-ray diffraction analysis and thermogravity/differential thermal analysis. READ MORE
