1. Characterization, Activation and Reactivity of Natural Pozzolans for Use as Supplementary Cementitious Materials
Sammanfattning : Supplementary cementitious materials (SCMs) represent one of the most practicable ways to reduce the negative environmental impact of cement. Natural pozzolans like clays and volcanic materials (VMs) offer promising alternatives to industrial by-products such as blast furnace slags and fly ashes, whose availability cannot meet the growing demand for SCMs globally.

2. Chloride initiated reinforcement corrosion in marine concrete
Sammanfattning : Factors affecting the total chloride threshold for initiation of pitting corrosion in reinforced concrete were investigated by means of field and laboratory exposure tests. Factors affecting the chloride penetration into concrete were also investigated by means of field tests. The thesis consists of a summary (86 p.) and 11 papers attached. LÄS MER
3. Transport and Sorption Phenomena in Concrete and Other Porous Media
Sammanfattning : The work presented in this thesis is mainly focused on transport processes involved in service life predictions of concrete. Two papers and three reports deal with ion transport in pore solution of concrete. LÄS MER
