You are tasked to design a concrete mix for a bridge that experiences severe weather conditions. Outline your approach including material choices and expected performance.
💡 Hint: Always think about environmental impacts and structural needs.
If a concrete mix requires 400 kg of cement, uses a water-cement ratio of 0.4, and has 1000 kg of coarse aggregates, calculate how much fine aggregates you would need based on typical proportions.
💡 Hint: Use proportions to find the balance!
