Durability testing of low clinker blends - chloride ingress in similar strength mortar exposed to seawater
Geiker, Mette Rica; De Weerdt, Klaartje; Ferreiro Garzón, Sergio; Jensen, Mads Mønster; Johannesson, Björn; Michel, Alexander (Chapter; Peer reviewed, 2017)Resistance to chloride ingress of ten different binders was investigated. Most of the binders were prepared with 35% substitution of a new clinker by limestone filler, calcined clay, burnt shale and/or siliceous fly ash. ... -

Screening of Low Clinker Binders, Compressive Strength and Chloride Ingress
Geiker, Mette Rica; De Weerdt, Klaartje; Ferreiro Garzón, Sergio; Jensen, Mads Mønster; Johannesson, Björn; Michel, Alexander (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 ...
