This report gives the findings from a collaboration project between the Norwegian Public Roads Administration (NPRA) and the COIN FA 2.1 project managed by SINTEF Building and Infrastructure which was start in spring 2010. The COIN FA 2.1 project "Robust and highly flowable concrete with...
The aim of this study, using LCA, is to 1) Assess CO2 emissions and embedded energy of a passive house roof construction, and 2) Identify the concrete with the lowest emissions and energy use The goal of this analysis was to find out, by applying the LCA methodology, the embedded energy and GHG...
This report is a post-occupancy evaluation of a recent energy efficient building. The building is located in Professor Brochs gate 2, in the city of Trondheim, the third largest Norwegian municipality. The building was erected in 2008-2009 and got partially moved in during September 2009. The...
This report addresses the potential for energy savings in lighting in buildings. The main emphasis is on office buildings but most of the solutions are applicable for other commercial buildings as well. Several means directed at reducing the lighting loads are discussed. The most important of these...
The present report is mainly a reference source covering details in concrete constructions with low thermal bridge values, in many cases also showing specific air tightness measures. Chapter 2 describes the Passive House concept, including definitions, criteria and main principles, and also methods...
The use of Self Consolidating Concrete (SCC) can lead to improved working environment, and better form filling and surface finishing. However, its use is limited due to the low robustness regarding stability, especially for low grade concrete e.g. NS-EN 206-1 M60 B30. This report builds further on...
Målsetningen med prosjektet er å bestemme åpning mellom hvelv og fjellvegg i Eidsvolltunnelen...
This report is a compilation of the characterisation methods and results performed at different institutes and companies to analyse four different fillers employed in a subproject Case study Velde in COIN FA2.3 High Quality manufactured sand for Concrete. Here, the application of different methods...
The objective of this state-of-the-art report (STAR) is to review work done to make pozzolana from natural occurring minerals by chemical treatment, and also outline principle possibilities of doing so. It does not include pozzolana by thermal treatment as for e.g. clays. Based on the theory of...
COIN was initiated as a Centre for research based innovation (SFI) by The Research Council of Norway. The COIN-programme started in 2007 and lasted for eight years and ended in 2014. A closure seminar was arranged in Trondheim 2 and 3 of December 2014 to mark the end of this period and to present...
This study focuses on ductility of lightweight aggregate concrete (LWAC) in compression. The major disadvantage of LWAC is the brittleness in compression at the material level compared to normal density concrete. Requirements for energy absorption and/or a controlled behaviour after peak load may...
The zeta potentials of five different fillers and three commercial plasticizers were explored in this report. The main purpose was to determine how these materials interact with each other to aid dispersions, in an effort to explain the macroscopic observations of sedimentations and interactions of...

Med solenergi menes i denne sammenhengen energi produsert i solcellepanel og solfangere. I disse omdannes strålingsenergi til henholdsvis elektrisitet og varme. Solenergi må konkurrere med andre energibærere og -teknologi. Siden økt utnyttelse av solenergi mest sannsynlig vil skje over mange år, er...
Arkeologien og bygge- og anleggsbransjen møtes like under bakkeplan i forbindelse med gravearbeider, og de to sektorene har allerede gjennom lang tid vært tett knyttet til hverandre gjennom lovverk og praksis. I Norge er over 90 % av de arkeologiske undersøkelsene og utgravningene initiert av...
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 increase in early strength development. This report gives a historical and...
Parameters influencing the workability of fibre concrete and maximum fibre content are given in this state of the art report along with the range of fibre types available on today’s market. The study reveales that new placing techniques and production methods are crucial in order to increase fibre...
