The RILEM approach to mitigate alkali aggregate reactions (AAR) in concrete
Development and assessments of test methods, to avoid deleterious AAR in concrete, have been the focus of three previous RILEM Technical Committees (TC) in the period 1989 to 2014. The 4th RILEM TC on AAR, TC 258-AAA, was ...
Determining the free alkali metal content in concrete – Case study of an ASR-affected dam
(Journal article; Peer reviewed, 2018)
In concrete affected by alkali–silica reaction (ASR), aggregates react in the high pH environment and cause deleterious expansion and cracking of the concrete. Leaching of alkali metals from the concrete might therefore ...

Excavated rock materials from tunnels for sprayed concrete
Sand extracted from natural resources is widely used in concrete production nowadays. The increase in demand for concrete production has resulted in shortage of natural sand resources, especially in terms of suitable ...

Low water permeability through hydrophobicity : COIN Project P1 advanced cementing materials : SP 1.5 F Low porosity / permeability
(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 ...
Ternary Blended Cements with Fly Ash and Limestone. Part I: Activation of Fly Ash. State of the art.
(SINTEF Rapport (SINTEF Byggforsk);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 ...
Influence of rheology on the pumpability of mortar : P 2 Improved construction technology SP 2.4 Workability
(COIN Project report;21, Research report, 2010)
The rheological and material parameters determining the pumpability of fresh self-compacting mortar have been studied in full-scale (70 m Ø 50 mm rubber hose and screw pump with max capacity 7 m3/h). Concrete pressure ...
