  1. 1. Sustainable concrete bridges : An investigation of possible measures to reduce the climate impact

    University essay from Luleå tekniska universitet/Byggkonstruktion och brand

    Author : Daniel Hugh; [2022]
    Keywords : Bridges; CO2; emission; cement; reinforcement; SCM; sustainability.;

    Abstract : The need of building new bridges is always existing in relation with the increase of infrastructureand transport needs. Bridge constructions have traditionally been associated with highconsumption of resources and large greenhouse gas emissions. READ MORE

  3. 2. Optimization of a one-part geopolymerization method for lab-scale, using waste glass wool as a precursor

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : Oscar Enander; [2022]
    Keywords : Materials chemistry; Geopolymer; Glass wool; Recycling; Curing time; Curing temperature; Cement; Chemistry;

    Abstract : Geopolymers are amorphous inorganic polymeric structures. They are used as binding agents and can be compared to cementitious materials such as ordinary Portland cement. This thesis aims to produce geopolymers from waste glass wool. Today glass wool is found in isolation, both thermal and sound insulation, and it is not being recycled. READ MORE

  4. 3. Accelerated Carbonation Of Cement Pastes And Mortars

    University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Author : Pejman Hajibabaei; [2022]
    Keywords : karbonatisering; accelerated carbonation; SCMs; cement paste; carbonation depth;

    Abstract : Concrete structures have the largest surface area of all human made structures. Large surface area makes concrete capable to absorb CO2 from environment during its lifetime. It is estimated that concrete during its lifetime can absorb about 15-20% of CO2 which had produced in cement production. READ MORE

  5. 4. GEOPOLYMERS WITH GREEN LIQUOR DREGS : An investigation of the possibility tomanufacture a geopolymer based on residual streams

    University essay from Umeå universitet/Kemiska institutionen

    Author : Martin Sundqvist; [2021]
    Keywords : ;

    Abstract : The pulp and paper industry make up a large part of the Swedish industry and is alsogrowing worldwide. With its growth, the amounts of residuals that are produced alsoincrease. The estimated annual global amount of residuals generated from pulp millsexceeds 1 million tons. READ MORE

  6. 5. Use of Agricultural Wastes as Supplementary Cementitious Materials

    University essay from KTH/Byggvetenskap

    Author : Ezio Marchetti; [2020]
    Keywords : Agricultural waste; Environmental impact; Concrete; Life Cycle Assessment; Oat husk ash; Rice husk ash; Supplementary cementitious materials; Sustainable Construction; Betong; Havreskalaska; Hållbar konstruktion; Jordbruksavfall; Kompletterande cementmaterial; Livscykelanalys; Miljövarudeklaration; Miljöpåverkan; Risskalaska;

    Abstract : Global cement production is continuously increasing from 1990 till 2050 and growing particularly rapidly in developing countries, where it represents a crucial element for infrastructure development and industrialisation. Every tonne of ordinary Portland cement (OPC) produced releases, on average, about 800 kg of CO2 into the atmosphere, or, in total, the overall production of cement represents roughly 7% of all man-made carbon emissions.
