2. Thermal Crack Risk Estimation and Material Properties of Young Concrete
Abstract : This thesis presents how to establish a theoretical model to predict risk of thermal cracking in young concrete when cast on ground or an arbitrary construction. The crack risk in young concrete is determined in two steps: 1) calculation of temperature distribution within newly cast concrete and adjacent structure; 2) calculation of stresses caused by thermal and moisture (due to self-desiccation, if drying shrinkage not included) changes in the analyzed structure.

3. Chemical Properties of FBC Ashes
Abstract : In this thesis several aspects of ash chemistry are discussed. An issue of primary concern for boiler operators is the formation of ash deposits. New biomass fuels are introduced, many of which have unfavourable ash melting behaviour due to high levels of alkali metal species and chlorine. READ MORE

4. Hydration, pore structure, and related moisture properties of fly ash blended cement-based materials : Experimental methods and laboratory measurements
Abstract : Cement-based materials, such as mortar and concrete, are the most employed construction materials in the world. Cement is an important component; it reacts with water to form a glue, called cement paste, which causes the material to harden. Today, cement production accounts for a significant portion of the world’s annual carbon dioxide emissions. READ MORE

5. Development of strength and heat of hydration of young concrete at low temperature - influence of granulated blast furnace slag, silica and limestone
Abstract : The work presented in this licentiate thesis was carried out within the project task Use of industrial by-products and filler in concrete, part Early-age strength development at low temperatures in concrete with mineral additions/fillers. To improve the understanding and to increase the data available, the study investigated the development of compressive strength and heat of hydration while curing at 5°C compared with curing at 20°C.
