Skjærkapasitet av ultrahøyfast fiberarmert betong – verifikasjon av designstandard
2018
Masteroppgave bygg BYG508 - Universitetet i Agder 2018 Ultra High Performance Fiber Reinforced Concrete (UHPFRC) is a concrete that is still not in use in Norway. This is, as the name implies, a strong concrete, with high ductility from the fibres. To be able to use this concrete in Norway in the future, it is necessary to develop a national standard for UHPFRC. The concrete is in use in some countries, some of these are France, USA, Japan and Canada. The French standard NF P18-710 is based on Eurocode 2, but it is customized for UHPFRC. The method to calculate the shear capacity is different, both because of the concrete and because of the use of fibres. To calculate how much the fibres wi…
Silica Green Stone as an SCM in concrete paving stones production : In order to reduce the total environmental footprint
2021
Master's thesis in Civil and structural engineering (BYG508) The cement industry is responsible for around 7% of the global CO2 emissions. Reducing this number has been on the forefront of the industry's mind for decades, but even with constant improvement and constant reduction in CO2 emissions per tonne cement used, the increasing globalization has kept the emissions high. Research in the industry has discovered supplementary cementitious materials (SCMs), that when partly replacing cement will produce most of the same results. SCMs are by-products from other industries and natural progression has led to the need for new ones. This thesis is, together with UiA, Aaltvedt Betong, SINTEF and…

Master's Thesis Civil and Constructional Engineering BYG508 - University of Agder 2019 Based on the results from pre-projectand workcovered by this thesis, no better alternatives to AISI 4130 material was found, neither could it be safely concluded for removal of NACE MR0175/ISO 15156 requirementsin any parts of high-pressure drilling fluid system. SinceAISI 4130 hasshown to be the optimal choice for the system,it was decided to look forimprovementsof welding procedure by optimization ofpost weld heat treatmentforthis steel.Heat treatment is an expansive and time-consuming procedure that,if not done correctly,could weaken the materialand jeopardize the safetyof the system.Inthis thesis, whi…

Application of Heavy Equipment Telematics in Infrastructure Projects : Method for automating collection of mixed fleet data, and optimization of proj…
2019
Master's Thesis Civil and Constructional Engineering BYG508 - University of Agder 2019 Existing heavy equipment telematics capabilities are not being used to their potential.In collaboration with Skanska there is an interest to look at how telematics can beused more efficiently with mixed equipment fleets. Current and future aspects are com-pelling, especially in relations to optimization and environmental benefits.Rv. 3 /rv. 25Løten–Elverumis provided as a case.This master’s thesis takes a closer look at the use of telematics data from heavy equip-ment at infrastructure projects. Through the automation of collecting telematics data,mixed fleet data are juxtapositioned to give insight into …
