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 ... -
