Acid Activation of Natural Rocks - A Case Study with Norwegian Anorthosite and Phosphoric Acid
Danner, Tobias; Justnes, Harald (SINTEF; 2021:00335, Research report, 2021)Norway is rich in natural resources, especially different types of rocks that could potentially serve as raw material for alternative binder concepts like alkali activated binders or magnesium phosphate and magnesium hydroxy ... -
Alternative binders based on lime and calcined clay
Østnor, Tone Anita; Justnes, Harald (COIN Project report;68, Research report, 2015)Alternative binders are in this report defined as binders without Portland cement. In this particular project it will be based on calcined clay or fly ash as a source of reactive silica and alumina in combination with lime ... -

Østnor, Tone Anita; Justnes, Harald (COIN Project report;50, Research report, 2014) -
Durability of mortar with calcined marl as pozzolan : FA 1 Environmentally friendly concrete : SP 1.1 Low carbon-footprint binder systems
Østnor, Tone Anita; Justnes, Harald (COIN Project report;49, Research report, 2013) -
Fly ash – Limestone Synergy in Ternary Cements. FA 1 Environmentally friendly concrete. SP 1.1 Low carbon-footprint binder systems
De Weerdt, Klaartje; Østnor, Tone Anita; Justnes, Harald (COIN Project report;46, Research report, 2013)The objective is to study the parameters of cements and fly ashes in combination with limestone that would optimize the synergistic chemical reaction between fly ash and limestone that leads to more bound water and thereby ... -
Hardening accelerators for fly ash blended cement. FA 1 Environmentally friendly concrete. SP 1.1 Low carbon-footprint binder systems
Justnes, Harald; Ng, Serina (COIN Project report;71, Research report, 2015)A former developed hardening accelerator for fly ash blended cement should be replaced with another formulation free from thiocyanate and preferentially with equal or better performance in terms of compressive strength. ... -
Low porosity through optimized particle packing of concrete matrix. COIN P1 Advanced cementing materials and admixtures : SP 1.5 Low porosity/ permeability
Justnes, Harald (COIN Project report;13, Research report, 2009) -
Low water permeability through hydrophobicity : COIN Project P1 advanced cementing materials : SP 1.5 F Low porosity / permeability
Justnes, Harald (COIN Project report;1, Research report, 2009)The durability and aesthetic appearance of concrete may be improved by the addition of hydrophobizing agents as a consequence of reduced water permeability. Hydrophobizing agents lead to less water absorption at the same ... -
Microstructure of clinker – fly ash interactions
De Weerdt, Klaartje; Østnor, Tone Anita; Justnes, Harald (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 ... -
Pozzolana from minerals – State of the art. COIN P1 Advanced cementing materials and admixtures. SP 1.4F Alternative pozzolans
Justnes, Harald (COIN Project report;16, Research report, 2009) -
Rheology of blended cements with superplasticizers : FA: Environmentally friendly concrete structures : SP 1.1 Binders with low emission and reduced resource consumption
Ng, Serina; Justnes, Harald (COIN Project report;58, Research report, 2015)
