Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Concept Moulding sand is a mixture of silica sand, clay (binder), and water.
Step 2: Meaning Bentonite is a specific type of high-quality clay used as a binder in foundry applications.
Step 3: Analysis The binder's role is to hold the sand grains together so the mould retains its shape when the pattern is removed.
Step 4: Conclusion Bentonite provides the necessary green strength and plasticity to the sand mixture. Final Answer: (C)
