Correlating the development of chloride profiles and microstructural changes in marine concrete up to ten years
(Peer reviewed; Journal article, 2022)After ten years of marine exposure, chloride and calcium profiles and petrographic data were obtained from the tidal and submerged zones of six concrete panels differing in binder composition. Moisture and portlandite ... -
The effect of curing temperature on autogenous deformation of fly ash concretes
(Peer reviewed; Journal article, 2020)For concrete subjected to restrained conditions, autogenous deformation (AD) and thermal dilation (TD) are the main driving forces behind stress development in the hardening phase. Generally, AD in concrete is modelled by ... -
Electrical resistivity measurements in steel fibre reinforced cementitious materials
(Journal article; Peer reviewed, 2018)This paper reports results from experiments aimed at better understanding the influence of fibre dosage and fibre geometry on the AC frequency needed to determine the DC resistivity of cementitious materials containing ... -
Friedel's salt profiles from thermogravimetric analysis and thermodynamic modelling of Portland cement-based mortars exposed to sodium chloride solution
(Journal article; Peer reviewed, 2017)Thermogravimetric analysis (TGA), powder X-ray diffraction (XRD) and thermodynamic modelling have been used to obtain Friedel's salt profiles for saturated mortar cylinders exposed to a 2.8 M NaCl solution. Comparison of ... -
In vitro and in situ tests to evaluate the bacterial colonization of cementitious materials in the marine environment
(Peer reviewed; Journal article, 2020)Civil engineers have a responsibility to take measures to protect marine biodiversity by selecting more bioreceptive construction materials in the design of marine infrastructure, for better biodiversity conservation. In ... -
Influence of crushed aggregate fines with micro-proportioned particle size distributions on rheology of cement paste
(Journal article; Peer reviewed, 2017)This paper presents a study on how crushed concrete aggregate fines affect rheological properties of cement paste. The fines (≤250 μm) were produced by high-speed vertical shaft impact (VSI) crushing of rock types from 10 ... -
Multi-scale strategy to estimate the mechanical and diffusive properties of cementitious materials prepared with CEM II/C-M
(Peer reviewed; Journal article, 2022)A procedure to estimate the mechanical and diffusive properties of cement pastes, mortars and concretes made with a novel CEM II/C-M (S-LL) binder that has been developed within the European EnDurCrete project, is presented ... -
Stability of the hydrate phase assemblage in Portland composite cements containing dolomite and metakaolin after leaching, carbonation, and chloride exposure
(Journal article; Peer reviewed, 2018)To reduce CO2 emissions during the production of cement and to cope with increasing demands for concrete, and thereby cement, the cement industry needs to identify new supplementary cementitious materials. These new composite ... -
Sulfuric acid and citric acid attack of calcium sulfoaluminate-based binders
(Peer reviewed; Journal article, 2022)Calcium sulfoaluminate (CSA) cement-based binders are low CO2 binders which exhibit rapid hardening or shrinkage compensating characteristics. Due to their unique properties, they have potential to be used in concrete ...
