1. 1. END-OF-LIFE FOR A QUARRY, WHAT IS THE ENVIRONMENTAL IMPACT?

   University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

   Author : Kimia Golamian Yosaf Abadi; [2023-06-21]
   Keywords : Quarrying; Aggregates; Life cycle; Environmental impact; Restoration; Permit;

   Abstract : Aggregates products are the largest non-energy mining industry in the world, which is the most extracted materials after water. The most prevalent source of aggregates is from quarries, or mines that target the rock itself. READ MORE

3. 2. Development of a DEM-FEM framework for infrastructure simulations

   University essay from Göteborgs universitet / Institutionen för fysik

   Author : Anita Ullrich; [2022-09-20]
   Keywords : ;

   Abstract : This thesis presents a coupling algorithm of the discrete element method (DEM) and finite element method (FEM). The algorithm formulates an explicit coupling of transient simulations of particle systems interacting with elastic bodies. READ MORE

4. 3. EVALUATION OF ENVIRONMENTAL AND TECHNICAL PERFORMANCE OF ALTERNATE FIBRES FOR SHOTCRETE IN TUNNELS

   University essay from KTH/Betongbyggnad

   Author : Shilpa Anand; [2022]
   Keywords : Shotcrete; Life cycle assessment; Environmental Product Declaration; Global warming potential; steel; basalt and synthetic fibres; flexural strength; energy absorption.;

   Abstract : Tunnels in hard and jointed rock are normally excavated in an arch shape to enable the rock mass to support its weight. Since the beginning of the 1980's, fibre reinforced shotcrete (FRS) in combination with rock bolts have been the dominating support method for hard rock tunnels. READ MORE

5. 4. Economic and environmental optimization of deep energy renovation strategies for an office building in Sweden

   University essay from Linnéuniversitetet/Institutionen för byggd miljö och energiteknik (BET)
