Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

You have 800 kg of aggregates with 2% absorption. Calculate the reduced water content that needs to be adjusted in your mix.

💡 Hint: Think about how absorption affects the total available water.

Challenge 2 Hard

If aggregates have 5% free surface moisture and your planned mix requires 200 kg of water, how much total water should you adjust for?

💡 Hint: Remember, free surface moisture adds to our planned amounts.
