RILEM TC 258-AAA Round Robin Test: Alkali release from aggregates and petrographic analysis. Critical review of the test method AAR-8
Menéndez, Esperanza; Silva, António Santos; Fernandes, Isabel; Duchesne, Josée; Berra, Mario; De Weerdt, Klaartje; Salem, Yasmin; García-Roves, Ricardo; Soares, Dora; Fournier, Benoit; Mangialardi, Teresa; Lindgård, Jan (Peer reviewed; Journal article, 2022)To create an international recommendation concerning the release of alkalis, test method AAR-8 was developed within the scope of RILEM TC 258-AAA activities. The first round robin test was performed using five aggregate ... -
Role of calcium on chloride binding in hydrated Portland cement–metakaolin–limestone blends
Shi, Zhenguo; Geiker, Mette Rica; De Weerdt, Klaartje; Østnor, Tone Anita; Lothenbach, Barbara; Winnefeld, Frank; Skibsted, Jørgen (Journal article; Peer reviewed, 2017)Chloride binding is investigated for Portland cement–metakaolin–limestone pastes exposed to CaCl2 and NaCl solutions. The phase assemblages and the amount of Friedel's salt are evaluated using TGA, XRD and thermodynamic ... -

Vikan, Hedda; De Weerdt, Klaartje (COIN Project report;25, Research report, 2010) -
Stability of SCC – robustness for changes in water content and sand grading. FA 2 Competitive constructions. SP 2.1 Robust highly flowable concrete
Martius-Hammer, Tor Arne; Smeplass, Sverre; De Weerdt, Klaartje; Peng, Ya (COIN Project report;47, Research report, 2013) -
Ternary Blended Cements with Fly Ash and Limestone. Part I: Activation of Fly Ash. State of the art.
De Weerdt, Klaartje (SINTEF Rapport;SBF BK A07023, Research report, 2007-12-13)There is a rising interest in the production of composite cements due to mounting environmental awareness and the diminishing natural resources. In composite cements considerable parts of the clinker is replaced by ... -
The effect of calcium lignosulfonate on ettringite formation in cement paste
Colombo, Alessia; Geiker, Mette Rica; Justnes, Harald; Lauten, Rolf A; De Weerdt, Klaartje (Journal article; Peer reviewed, 2018)The effect of a softwood calcium lignosulfonate, LSs, on the ettringite formed in cement paste was investigated. Two Portland cements, mainly differing in surface area and C3A content, were used. The effect of LSs addition ... -
The effect of stabilization with either filler or chemical stabilizer on the surface quality of concrete elements. FA 2 Competitive constructions. SP 2.1 Robust highly flowable concrete
De Weerdt, Klaartje; Eide, Mari Bøhnsdalen; Smeplass, Sverre; Wirthova, Micheala (COIN Project report;39, Research report, 2012)Three full scale wall elements were cast with three different concretes: an unstable SCC, one stabilized by adding filler, and one stabilized by adding chemical stabilizer. The aim of this study was to investigate the ... -
