A Review on Fatigue Performance of Concrete Structures Part II, Material Parameters and Environmental Factors
(Peer reviewed; Journal article, 2023)Fatigue is a critical issue for concrete structures subjected to repetitive and varying loads,particularly in infrastructure and transportation systems. This review paper presents acomprehensive overview of the current ... -
Screening of Low Clinker Binders, Compressive Strength and Chloride Ingress
(Journal article; Peer reviewed, 2017)This paper reports an initial screening of potential new binders for concrete with reduced CO2- emission. Mortars cured saturated for 90 days are compared with regard to a) compressive strength of mortars with similar ... -
SEM-EDS analysis of products formed under natural and accelerated carbonation of concrete with CEM I, CEM II/B-M and CEM II/B-V
(Chapter; Peer reviewed, 2017)Carbonation resistance of concrete is usually tested under accelerated conditions, i.e. by elevating the CO2 concentration compared to natural conditions and keeping the RH close to 60%. However, it is not clear if these ... -
Shape and Size of Particles Scaled from Concrete Surfaces during Salt Frost Testing and Rapid Freeze/thaw in Water
(Peer reviewed; Journal article, 2021)Thickness (T), Length (L), Width (W) and size distribution of scaled concrete particles in frost testing were measured. T (mm) increases with particle size surprisingly similarly for different concrete qualities and frost ... -
The Particle-Matrix model: limitations and further improvements needed
(Journal article; Peer reviewed, 2017)According to the Particle-Matrix Model (PMM) philosophy, the workability of concrete depends on the properties of two phases and the volumetric ratio between them: the fluid matrix phase (≤ 0.125 mm) and the solid particle ... -
Towards the Understanding of the pH Dependency of the Chloride Binding of Portland Cement Pastes
(Journal article; Peer reviewed, 2018)Hydrated Portland cement paste exposed to a NaCl solution was acidified by adding HCl in small steps, gradually lowering the pH. The chloride binding of the cement paste changed as a function of the pH. For the range of ... -
Use of Concrete for Road Infrastructure: A SWOT Analysis Related to the three Catchwords Sustainability, Industrialisation and Digitalisation.
(Peer reviewed; Journal article, 2019)This paper aims at identifying the direction for more sustainable development of the use of concrete in road infrastructure in an industrialised context. The increase in the global mean temperature is one of the most severe ... -
When and How Should Chloride Profiles be Calibrated for Paste Fraction?
(Peer reviewed; Journal article, 2022)Due to stochastic and systematic variations in the paste fraction, data for total chloride content are occasionally calibrated using parallelly measured calcium content as a measure of the actual paste fraction − assuming ...
