1. A Quantitative Thermogravimetric Study on the Nonevaporable Water in Mature Silica Fume Concrete: Influence of Carbonation and Moisture Conditions
Sammanfattning : The primary goal of the project presented here was to study and quantify the influence of materials parameters (cement type, silica fume content, w/c ratio, type and dose of superplasticizers) and environmental parameters (carbonation and moisture history) on the nonevaporable water in hydrated cement composites. In order to achieve this, a thermogravimetric method which separates different types of nonevaporable water (bound in different hydrates and hydroxide) and carbonation products was developed. LÄS MER
2. Sensing capability of nanomodified Portland cement composites
Sammanfattning : Sensing cement-based composites refer to composites that have sensing functionality that can measure several physical and chemical parameters. Sensing cement-based composites are fabricated by incorporating some functional fillers, such as conductive fibers (CFs), carbon nanofibers (CNFs), carbon nanotubes (CNTs), and graphene, into conventional concrete.

3. Influence of solid solutions on the properties of some apatite-type calcium salts relevant to the production of phosphate and silicate cements
Sammanfattning : The effects of non-stoichiometry and isomorphic substitutions on the properties of some apatite-type compounds were investigated. These investigations were performed both in the fields of Portland cement chemistry and apatitic calcium phosphate-based biocements. LÄS MER
4. Frost-induced deterioration of concrete in hydraulic structures : Interactions between water absorption, leaching and frost action
Sammanfattning : Frost deterioration of concrete can result in severe consequences to the safety, durability and functionality of a structure since it impairs the strength of the concrete. Frost damage may occur to structures that are in contact with water and subjected to frost action. LÄS MER
5. Exploring microfluidics as a tool to study cell-biomaterial interactions
Sammanfattning : Considering the tremendous amount of research on the development of novel biomaterials, relatively few of these have reached the patient. This can at least in part be explained by the lack of predictive power of the currently used in vitro models, which are nowadays recognized to be too reductionist to accurately predict in vivo complexity.
