Concrete is one of the world?s most common Construction materials and is composed of 70-80 % stone material. Today crushed stone is used as aggregate in concrete in order to replace natural aggregates due to strong environmental reasons. Stone crushing yields flaky material and in this thesis studies are made on the flaky particle shape and how it influence properties of concrete such as workability, rheology and strength. The concrete recipes used in this thesis have fixed values, the only variable is the flakiness of the crushed stone.

Context: During the 21st century several alarming reports have been published that deals with the depletion and pollutant of the earth by human interference. The earth is an ending resource and so are the mountains and bedrocks which are continuously mined in order to harvest its minerals. The idea behind Urban Mining is to (re)invent processes enabling further purpose for materials both from old deposits and new products providing secondary raw materials and energy. This thesis aims to investigate the challenges and opportunities of how firms and organizations can and will be able to strike a better balance between product-/service systems, economic growth and environmental stewardship in the context of Urban Mining as an approach. With the innovation of processes, technology, business- planning and creation in focus.Objective: How to future proof a business model for Urban Mining by the usage of business model design.Method: This thesis will be conducted using a case study approach, meaning that it will incorporate qualitative, exploratory and descriptive characteristics - aiming towards enabling both applied and fundamental research.Results: The result evaluates the business model element differences between traditional C&D industry and Urban Mining industry.

Byggsektorn står för en stor del av det totala avfallet i Sverige och står därmed inför stora miljöutmaningar. Däribland finns NCC Construction Sverige (nedan kallat NCC), Sveriges tredje största byggföretag med cirka 10 000 anställda. På varje bygg- eller anläggningsarbetsplats på NCC upprättas en miljöplan där olika krav omhändertas: lagkrav, lokala föreskrifter, beställarkrav samt interna krav.Studien genomfördes i samband med författarens praktik på NCC i Göteborg, avdelning Anläggning, med syftet att synliggöra yrkesarbetare, arbetsledare och platschefers syn på miljöarbetet på företaget - idag och historiskt. Totalt genomfördes 8 anonyma personintervjuer; två platschefer, två arbetsledare och fyra yrkesarbetare intervjuades under hösten 2014.Studien visade att ekonomiska incitament är viktiga för att miljöarbetet ska kännas berättigat för dem som utför det - framför allt för skeptikerna. Pappersbördan är hög och vissa anser att miljöarbetet enbart är en pappersprodukt utan egentlig mening.

The purpose of this study is to facilitate sustainable building by the use of BIM. The goal is to determine which aspects of sustainable building, which can be analyzed mainly with BIM tools, but also other aids.The study is based on literature studies and interviews. The literature review examines aspects important for sustainable building by studying environmental certification systems applicable in Sweden, as well as the BIM tools available on the market to analyze these aspects. The literature also includes the concepts of BIM and sustainability in order to provide a clearer view of its meaning. The interviews have brought the study's overall understanding of the industry and guidance on the subject.The results are presented in a table, where the aspects relevant to sustainable building are listed.

Travelling children is the topic of my work. Children who commute between more than one home. Society is rapidly changing and so is the concept â familyâ . The nuclear family is no longer the most common one. Children are now travelling more frequently than ever.

In this report the balconies? abutments for a property in Bo01-area in Malmö has been studied. The property which is called Vitruvius contains four build-ings where two of them have corbelling balconies with intermittent abutments. With intermittent abutment means that the 50 mm thermal bridge insulation that the balconies is equipped with, is broken regularly by a 300 mm concrete heel. The reinforcement bar that holds the balcony runs through this heel.

The purpose of the thesis Masculinities ? Gender and its Impact on the Social conditions of individuals is to perform a critical study of how gendered norms influence the social conditions of individuals. This has been done by a problematization and the attempt to answer the question of how the hegemonical masculinity can be analyzed as a discourse, and how the structural aspects of this discourse inflict on the social conditions of masculinities.The question was divided into the analytical themes: the boarders of the discourse, the institutionalization of the discourse, the actuation of the discourse and the agents of the discourse. The theoretical frame is constituted by the theory of discourse by Michel Foucault, the theory of the hegemonical masculinity by R.W. Connell and a subversive identity theory by Judith Butler.

This degree project has been performed along with Classic Garden in Gothenburg andBallongfirman Far & Flyg in Stockholm. Together we have developed a sun- wind- andrain protection. The protection is permanently assembled and mainly intended for publicenvironments as restaurants and outdoor cafés.The design on the sun protection was already done so our task has been to develop theconstruction and to build a prototype in scale 1:4 and one in scale 1:1. The look of thesun protection is approximately as the name implies, equal an igloo. The lamellae aregoing to fold out in different steps all the way down to the ground and the both sides willbe independently of each other.The first stage in the project was to develop differently principle proposal on how thefunction will work when folding in and out the protection.

At Sandvik Materials Technology, Argon gas is used as furnace atmosphere when heattreating hot rolled wire. Upon heating chromium steel wire, a rich oxidelayer forms on the wire surface. The abstract of this masters thesis is to enhance the understanding of the constitution of the oxidelayers and the influence of the furnace atmosphere. This will be achieved by performing a number of annealing experiments on laboratory level. Also, the aim is to understand the chemical reactions and physical mecanisms controlling the pickling process.

This bachelor thesis project has been executed at Outotec Sweden AB in Skellefteå. Outotecs main business focus is selling mineral and metal processing technologies. A rest product from the metal process is particle-polluted gas and cyclone designs are today the most commonly used abatement device for particle control. A cyclone provides a simple design with high efficiency particle percolation by using air streams.The purpose of this work is to reduce the time it takes create new cyclone designs in Outotecs projects. An extensive construction work is needed for every new cyclone order due to new designs.

This thesis is a study of humidity at Knauf Danogips external plasterboard. The study is performed at the building project Kv. Maskinen in Jönköping in cooperation with NCC Construction AB and Knauf Danogips. The measuring was performed during five winter/spring months to see how the weather influenced the plasterboard.The measuring was performed at a small two-storied building and a larger fourstoried building. From the buildings` placement were a couple of measuring dots selected and to get a good result was the dots located in the four cardinal points.

Good comfort for the driver of a construction machine is crucial. Gearshift comfort is an important part of the total comfort. Volvo Construction Equipment Components has a simulation environment of the powertrain, SimPow, which is implemented in Matlab/Simulink. SimPow is mostly used for simulation of control strategies and performance. In order to be able to study gearshifting comfort, Volvo has an interest in developing new models for SimPow.

Hårdgörning av trä syftar till att göra materialet hårdare. Detta går att åstadkomma genom komprimering, det komprimerade materialet tenderar dock att återgå mot sin ursprungsform då materialet utsätts för fukt om ingen låsning sker. Låsningen kan ske mekaniskt i en treskiktskonstruktion som motverkar träets fuktrörelser. Dessa skivor har dock visat sig vara instabila och tidigare försök har uppvisat deformationer i form av kupning. Denna undersökning syftar till att utreda förutsättningarna för att använda komprimerad asp samt att ta fram underlag för framtagning av en kommersiell produkt.Praktiska tester har genomförts för att studera hårdhet, återfjädring och densitet hos det komprimerade virket.

This project has been created with the assistance of Fredells. Fredells is a Stockholm based company with a focus on the retail of building products. Fredells also produces prefab- or prefabricated products which are either completely or partially ready for assembly the moment they arrive to the building site. These prefab-products are primarily delivered to customers within the Stockholm region. The building industry is a conservative market where the incentive to changes has been relatively low compared to other industries.
