1. Environmental and technical evaluation of cement reduction and test methods for fibre reinforced shotcrete in tunnels
Master-uppsats, KTH/BetongbyggnadSammanfattning : The dominating support method for hard rock tunnels today is use of fibre reinforced shotcrete in combination with rock bolts. The fibre reinforced shotcrete secures smaller blocks, while rock bolts are used to support larger blocks in the rock. Application of shotcrete is done by spraying against the rock surface using compressed air. LÄS MER
2. Acceleratorers inverkan på betong avseende bearbetbarhet, pumpbarhet och hållfasthetstillväxt
Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Institutionen för samhällsbyggnad och industriell teknikSammanfattning : The following thesis is a comparison study which was performed in cooperation with Sika Sverige AB. The project was to examine concrete’s behaviour while being subjected to different accelerators which is used to speed up the hardening process in young concrete. Sika provided the materials and the instructions for the tests that were made. LÄS MER
3. Förändringar i tid- och resursplanering vid gjutning med slaggbetong
M1-uppsats, Jönköping University/JTH, Byggnadsteknik och belysningsvetenskapSammanfattning : Syfte: Genom att ersätta en del av cementen med tillsatsmaterial såsom flygaska eller mald granulerad masugnsslagg (MGMS) kan en betong med minskat utsläpp av koldioxid (CO2) uppnås. Dessa tillsatsmaterial reagerar långsammare en rent cement vilket leder till en försämrad hållfasthet de första dygnen. LÄS MER
4. Climate enhanced concrete in the civil engineering industry
Master-uppsats, KTH/BetongbyggnadSammanfattning : In 2017, the Swedish Parliament stated a new climate law with the goal that Sweden should be climate neutral by 2045. The concrete industry has developed a roadmap on how the goal for 2045 can be achieved, where one way to reduce the carbon emissions from concrete is by replacing a part of the cement clinker with alternative binders in the concrete mix.

5. Expansion of Sickla treatment plant : A study about the replacement of standard concrete to green concrete
Master-uppsats, KTH/BetongbyggnadSammanfattning : Stockholm Vatten has decided to close down the Bromma waste water treatment plantand manage the waste water from Bromma together with the waste water from the formerEolshällsverket to Henriksdal’s waste water treatment plant. Henriksdals wastewater treatment plant will be expanded for higher purification requirements and loads,estimated to be finished until 2040. LÄS MER
