Summary
This document contains study questions for an advanced course on building materials. It covers topics such as material characteristics, degradation mechanisms, and the carbon footprint of different materials. The questions encourage students to compare and contrast different building materials like steel, concrete, and wood, and explore innovative hybrid solutions for sustainable construction.

**STUDY QUESTIONS In Building Materials, Advanced Course (AF2301)** ***Topic 1. General introduction on building material science*** *Some basics* 1. What characterizes isotropic and anisotropic materials, respectively? Give examples of each type of material. 2. State the mathematical relationship between porosity, bulk density and compact density of a material. 3. The degradation mechanisms of building materials can be divided into five main groups. Which? Give an example of degradation for each main group. 4. What does the concept of synergism mean in connection with testing of durability? Give an example. 5. Define what is meant by a renewable biobased building material. 6. What is the most common organic material on Earth? *Comparisons between the building materials steel, concrete and wood* 7. Practice on "mapping" some significant characteristics and differences between concrete, steel and wood considering the chart "raw materials-processing-structure-properties-use" 8. Make a comparison between the building materials steel, concrete and wood related to carbon dioxide emissions in the production of the raw materials pig iron, cement clinker and wood 9. Give a proposal for a so-called hybrid material system or structure between steel, concrete and wood where the materials work together and utilize the advantages of the respective materials. Try to base your suggestion on the materials\' ratio between strength and density, and between the materials\' E-module and density. 10. In 2020, about 6 billion (10^9^) metric tonnes cement was produced in the world which corresponds to ca 8 % of the world´s CO~2~ emissions.\ \ Make an estimation if it is realistic that ca 50% of the world's use of concrete can be substituted with wood. If not, what would be your suggestion of a realistic strategy to drastically reduce the CO~2~ emissions from the building sector? (Additional material statistics: ca 0.5 billion m^3^ sawn wood and ca 0.5 billion m^3^ wood panels are today produced annually in the world).
