In this comprehensive unit, titled "From Raw Materials to Concrete: The Science of Portland Cement Manufacturing," students will embark on a fascinating exploration of the entire process of Portland cement production. They will delve into the fundamental aspects of Portland cement, including its definition, constituents, functions, and various types. Students will also explore the processes involved in cement manufacturing, focusing on both the wet and dry methods. They will differentiate between these production processes, analyzing their advantages, and disadvantages.

This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:
"Indoor microbes can release harmful volatile organic compounds (VOCs), but how environmental factors and microbial community composition impact microbial VOC emissions is unclear. To learn more, researchers recently subjected drywall and carpet to different equilibrium relative humidity levels and quantified microbial communities and microbial VOC emissions. Fungus grew in dusty carpet when the humidity was >75% and in inoculated painted drywall when the humidity was >85%. The dust sample collection site and the material type significantly affected the fungal and bacterial species compositions. In dusty carpet, increased humidity was associated with decreased microbial species diversity. Abundant VOCs were likely released from the materials and dust themselves, but some microbial VOCs, such as C₁₀10H₁₆H⁺ (monoterpenes) and C₂H₆SH⁺ (dimethyl sulfide and ethanethiol), were released from microbes that grew in dusty carpet. At 95% humidity, dusty carpet produced 5..."
