Host rock consists of calcareous and non-calcareous sediments of the Cassiar Platform, mainly biotite schists, limestone units, and the monzogranite unit of the Cassiar Batholith. READ MORE

  5. 4. Quarry Stories - Architecture through Narrative Exploration

    University essay from KTH/Arkitektur

    Author : Anastasia Bos; Lycke Förell; [2023]
    Keywords : Book; Exhibition; Post-humanism; Limestone; Quarry; Storytelling; Narrative; Landscape; Exploration; Non-human;

    Abstract : This book, Quarry Stories - Architecture through Narrative Exploration, collects the process and proposals of our thesis, responding to the question: How can critical post-humanist philosophy, using stories as a tool, enhance our understanding of architecture and activate narratives in limestone quarries? We view the limestone quarries on Gotland as an example of humans’ relationship with nature: we take what we want and leave. Although significant for the industry, the quarries are troublesome from an ecological perspective. READ MORE

  6. 5. The Effect on Mechanical Properties in Biochar Replaced Cement & Aggregate in Concrete Before and After Fire Exposure

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser
