Accelerating admixtures for concrete. State of the art
(SINTEF report;SBF BK A07025, Research report, 2007)Accelerating admixtures affect the rates of reactions between cement and water to give an overall increase in the hydration rate. Thus, the use of accelerators in concrete provides a shortening of setting time and/or an ... -
Calcareous smectite clay as a pozzolanic alternative to kaolin
(Journal article; Peer reviewed, 2019)The hydration of cement pastes with addition of a kaolinite rich clay (Clay A) and a calcareous smectite rich clay (Clay B) was investigated with isothermal calorimetry, in-situ XRD, PXRD, TGA and EPMA. Portland cement was ... -
Characterisation of calcined raw clays suitable as supplementary cementitious materials
(Journal article; Peer reviewed, 2018)The potential use of two raw clays (Clay A: kaolin; Clay B: calcareous montmorillonite) as supplementary cementitious material (SCM) in blended cements was investigated. Cement replacement in mortars by 20% calcined Clay ... -

Characterization of cement types used for rock injection
(Conference object; Peer reviewed, 2016)This paper is a part of the research project “True Improvement in Grouting High pressure Technology for tunneling (TIGHT)" financed by the Research Council of Norway (project no. 236676/O30), in cooperation with Statens ... -
Characterization of cements for injection
(Chapter, 2017)The three most common cement s for rock injection in Norway were characterized in terms of grout flow properties, stability and initial set for w/c = 1.2, 1.0, 0.8 and 0.6 at 8 and 20°C. The fineness was characterized by ... -

Microstructure of clinker – fly ash interactions
(COIN Project report;69, Research report, 2015)The first objective was to find out why a white clinker from previous studies has a higher strength potential than the other 3 clinkers tested in the same study, as well as finding out whether or not it contains other ... -
On the effect of calcium lignosulfonate on the rheology and setting time of cement paste
(Journal article; Peer reviewed, 2017)The effect of softwood calcium lignosulfonate, LSs, on the rheology and setting time of cement paste has been investigated. Two Portland cements with different surface area and C3A content were used. The lignosulfonate was ... -

Quality improvers in cement making – State of the art : COIN Project P1 Advanced cementing materials : SP 1.1F Reduced CO2 missions
(COIN Project report;2, Research report, 2009)It has been shown that the overall cement properties are interconnected and in many cases there is still potential for further production improvement by only optimising the different stages (e.g. separate grinding, mill ... -
Role of calcium on chloride binding in hydrated Portland cement–metakaolin–limestone blends
(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 ... -
