Challenge Problems
Push your limits with advanced challenges
Given a design mix requiring 150 kg of cement with a water-cement ratio of 0.55 and aggregates with 3% surface moisture, how would you calculate the total water required?
💡 Hint: Start by calculating water based on cement, then factor in moisture from aggregates.
You are tasked with adjusting a mix for higher workability, where the original calculation defined 200 liters of water. Considering that the desired slump increases by 25mm, how would you adjust your water needed?
💡 Hint: Refer to tables or guidelines provided in IS standards regarding workability adjustments.
