1. 1. AIR CLASSIFICATION OF FINE AGGREGATES

   Författare :Robert Johansson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CFD; Fines; Manufactured sand; Aggregates; Air classification; Concrete;

   Sammanfattning : Aggregates are defined as particles of rock which in combination are used as a civil engineering material. It is used in bounded form in asphalt and concrete. Historically natural sand has been used as fine aggregates for concrete production in Sweden. LÄS MER

3. 2. Bruk av kalk och sand ur ett hantverkligt perspektiv

   Författare :Jonny Eriksson; Göteborgs universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Eriksson method; mortar; lime putty; quenching methods; lime-kilns;

   Sammanfattning : Sweden has a thousand-year history of burning (calcinating) and slaking (hydrating) limestone to produce a binder for mortar and stucco. We can assume that the conditions for manufacturing such binders have varied from one part of the country to another. LÄS MER

4. 3. Towards understanding the fatigue behaviour of Alloy 718 manufactured by Powder Bed Fusion processes

   Författare :Arun Ramanathan Balachandramurthi; Per Nylén; Robert Pederson; Johan Moverare; Filippo Berto; Högskolan Väst; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fatigue; Additive Manufacturing; Powder Bed Fusion; Superalloy; Microstructure; Surface Roughness; Production Technology; Produktionsteknik;

   Sammanfattning : Additive Manufacturing (AM) is a disruptive modern manufacturing process in which parts are manufactured in a layer-wise fashion. Among the metal AM processes, Powder Bed Fusion (PBF) technology — comprised of Electron Beam Powder Bed Fusion (EB-PBF) and Laser Beam Powder Bed Fusion (LB-PBF) —has opened up a design space that was formerly unavailable with conventionalmanufacturing processes.

   Sammanfattning : Aggregate is defined as particles of rock which in combination are used as a civil engineering material. It is used in bounded form in asphalt and concrete. Historically natural sand has been used as fine aggregate for concrete production in Sweden. LÄS MER

7. 5. Modeling of Vertical Shaft Impact Crushers

   Författare :Simon Grunditz; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; DEM; VSI; Energy Modeling; Breakage Modeling;

   Sammanfattning : One of the largest products in most civilized societies is concrete used to build various types of constructions. To create this product, a mixture of cement, chemical binders, and rock aggregates are combined and then poured into molds where it hardens. The sand part of the rock aggregates is either from natural sources or manufactured. LÄS MER
