Given that a concrete mix without SCMs has a carbon footprint of 450 kg of CO2 per ton, calculate the potential reduction when using SCMs that reduces this by 25%.
💡 Hint: Consider the percentage of reduction applied to the total emissions.
Assuming a pavement uses 2000 tons of concrete, determine the amount of fly ash required if it replaces 30% of the cement content, given the cement content is 300 kg/m³ and the total volume is 1000 m³.
💡 Hint: Calculate the volume of cement first, then apply the percentage to find the amount of fly ash.
