Challenge Problems

Push your limits with challenges.

Question 1

A contractor wants to create a mix for a waterproofing membrane using PMC. They need a total volume of 5 m³. If using 400 kg/m³ cement and maintaining a water-to-cement ratio of 0.4, calculate the amount of polymer, water, fine aggregates, and coarse aggregates needed.

💡 Hint: Work step-by-step based on volumetric requirements.

Question 2

You are tasked with designing an eco-friendly PMC mix. Discuss which additives might be beneficial and why, considering the implications of polymer and environmental sustainability.

💡 Hint: Think about each component’s role and environmental impact.
