2. 21. Moisture transport processes in Scots pine - Anomalous capillary suction. Nonisothermal diffusion

   Author : Ingemar Segerholm; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; moisture transport coefficients; nonisothermal; anomalous capillary suction; flux equation; phenomenological approach; wood;

   Abstract : Moisture transport processes in wood have become increasingly important with the growing use of wood as construction material. This thesis deals with two key processes: capillary suction and nonisothermal diffusion. In the study on capillary suction, several methods were used. READ MORE

4. 22. Investigations on moisture damage-related behaviour of bituminous materials

   Author : Umaru Bagampadde; Ulf Isacsson; Manfred Partl; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Moisture damage; State-of-the-Art; Stripping; Moisture sensitivity; Bituminous materials; Construction engineering; Konstruktionsteknik;

   Abstract : This doctoral thesis presents results of literature review on classical and contemporary aspects of stripping, as well as experimental investigations on moisture damage as influenced by bituminous materials. Previous research in the area of moisture damage was reviewed and synthesized into a state-of-the-art. READ MORE

5. 23. Water and alkali salts in the hydrating and hardened green cement-based materials: Hydration process, moisture content and transport

   Author : Liming Huang; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Formation factor; Electrical conductivity; Moisture transport; Pore structure; Sustainable cement-based materials; Hydration; Alkali salts; Supplementary cementitious materials;

   Abstract : Reducing CO2 emissions in the production of cementitious binder is the most effective way to decrease the environmental impact of the construction industry, so a large amount of supplementary cementitious materials (SCMs) has been used in the green concrete. Both the SCMs and alkali salts in binders influence the hydration process and the structure in hardened cement-based materials. READ MORE

6. 24. Studies of moisture and alkalinity in self-levelling flooring compounds

   Author : Anders Anderberg; Avdelningen för Byggnadsmaterial; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; alkalinity; SLC; floor screed; moisture transport; self-levelling flooring compound; Material technology; diffusion coefficient; materialteknik; Materiallära; secondary emissions; sorption isotherm;

   Abstract : In recent decades there has been an increasing interest in the indoor environment and its connections with public health. One important topic discussed has been the relation between the moisture in buildings and health. Cementitious materials, when cast, contain excess water since this is necessary for workability and for flow properties. READ MORE

7. 25. Characterising the Deformation Behaviour of Unbound Granular Materials in Pavement Structures

   Author : Mohammad Shafiqur Rahman; Sigurdur Erlingsson; Charles Schwartz; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; unbound granular materials; resilient modulus; permanent deformation; moisture; model; multistage; repeated-load triaxial test; Transportvetenskap; Transport Science; Civil and Architectural Engineering; Byggvetenskap;

   Abstract : Unbound granular materials (UGMs) used in the base and sub-base layers of flexible pavements play a significant role in the overall performance of the structure. Proper understanding and characterization of the deformation behaviour of UGMs in pavement structures are, therefore, vital for the design and maintenance of flexible pavements. READ MORE
