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 and calcium sulphate (e.g. gypsum) and/or calcium carbonate to stabilize...

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 less porosity and higher compressive strength. Most notably this will be the...

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. The 3rd component in the ternary accelerator consisting of 5 parts glycerol...

Due to depletion of natural sand resources in many central locations, it is an increased production and utilisation of crushed sand for concrete purposes. This crushed and processed sand is referred to as; Manufactured sand. Due to high and often variable content of fines (i.e. material less than...

Materialvalg og konstruktiv utforming av moderne trevinduer er avgjørende for vinduets egenskaper slik som luft- og regntetthet, styrke, varmeisolering og bestandighet. Optimalisering av design for best mulig ytelser for alle egenskapene er nødvendig for å oppnå et vindu med lang levetid. Et...

Many of the suggested methods for testing of SCC stability are quite demanding in execution and therefore seldom used in field. Furthermore, questions have been raised about how well they represent the stability problems in situ. The aim of the present investigation was therefore to find a method to...

Statens bygningstekniske etat (BE) har ønsket å få utredet konsekvensene av ulike ambisjonsnivåer for krav til varmegjenvinning fra ventilasjonsluft, samt eventuelt tilleggskrav til energieffektiv utforming av bygningers fasade. I tillegg skal energirammene i forskriften (TEK2007) justeres med...

A Round-Robin test program (inter-laboratory study) on energy absorption capacity of round panels is presented. The panels were tested according to the procedure described in Norwegian Concrete Associations Publication no. 7, 2011 (NB 7:2011). Four laboratories participated in the program: o...

Målet med studien ""Boligkvalitet i et samfunnsperspektiv"" har vært å undersøke hvilke faktorer som hemmer og hvilke som fremmer implementeringen av kvaliteter knyttet til Huabnskens bokvalitetsområder. fra tidligere studier vet vi at boligkjøperer bare i liten grad etterspør de kvalitetene som...

Background The perception of high pressure at various social arenas may be important sources of stress that influences well-being. That said, it is unclear how perceived pressure among adolescents has changed over the past decade, and whether this trend is consistent across different subgroups of...

Mer strukturert informasjon kan gi bedre forebygging og mer rettferdige forsikringsordninger. Når kraftig regn fører til oversvømmelser, når høststormer river av tak, eller når jordmassene raser ut etter perioder med nedbør og snøsmelting, sitter noen igjen med skadene. I Norge har vi god...

Atlantic salmon (Salmo salar L.) experience periodic drops in dissolved oxygen (O₂) inside aquaculture sea cages. In order to evaluate whether fish function or welfare is compromised during such drops in O₂ (termed hypoxia), it is necessary to establish the limit for acceptable O₂ reductions; the...
