What is the primary reason for the high carbon footprint in concrete?
Think about which ingredient in concrete has the highest environmental impact.
True or False: Using recycled aggregates can decrease concrete's durability.
Consider the benefits of reusing materials.
Given that cement production contributes significantly to CO₂ emissions, propose a sustainable concrete mix design using various SCMs, detailing their impacts on strength and emissions.
Consider the balance between performance and environmental impact.
Analyze a life cycle of a typical concrete structure and identify at least three stages where CO₂ emissions can be reduced. Provide strategies for each stage.
Trace the concrete's journey and think about where waste can be minimized.
