Alkali-reduced Bauxite Residue as Novel SCM
(Peer reviewed; Journal article, 2020)Bauxite residue is a major waste stream available in large volumes globally that can cause risks to the surrounding environment (e.g. ecotoxicity) when disposed and stored by conventional methods. There is yet no large-scale ... -
Bauxite Residue as Supplementary Cementitious Material – Efforts to Reduce the Amount of Soluble Sodium
(Peer reviewed; Journal article, 2020)This study investigates the feasibility of using bauxite residue (BR) as supplementary cementitious material (SCM) for the cement and concrete industry. It is shown from pastes of BR and calcium hydroxide, that BR is highly ... -
Durable Aluminium Reinforced Environmentally-friendly Concrete Construction – DARE2C
(Journal article; Peer reviewed, 2017)A new concept is described for low pH concrete that can allow reinforcement with aluminium metal rods or fibres. In regular concrete the high pH will after short while lead to substantial amounts of hydrogen gas evolution. ... -
Filler and Water Reducer Effects on Sedimentation, Bleeding and Zeta-Potential of Cement Paste
(Journal article; Peer reviewed, 2018)Bleeding and sedimentation quantify the stability of fresh cement paste, whereas the addition of fillers and water reducers affect the stability. The effect of various types of fillers and water reducers was investigated ... -
Non-destructive Test Methods for Corrosion Detection in Reinforced Concrete Structures
(Peer reviewed; Journal article, 2020)Several inspection methods can be used to assess the corrosion state of steel reinforcement in concrete. Especially for periodical field surveys and monitoring, non-destructive testing (NDT) methods are to be preferred as ... -
The Influence of Production Parameters on Pozzolanic Reactivity of Calcined Clays
(Journal article; Peer reviewed, 2018)Calcined clays are gaining increasing interest as future supplementary cementitious materials for the production of blended cements. Besides the mineralogy, the right production conditions can affect the pozzolanic activity ...
