Short answerNeither is automatically better. Good M-Sand, produced and tested to standard, can match river sand for concrete and masonry and is more consistent in supply. River sand is naturally rounded but supply is limited and quality varies by source. Choose based on grading, cleanliness and test results.

Frequently Asked Questions
Is M-Sand safe for RCC construction?
Yes, when it is produced to the relevant standard and tested for grading and fines. Mix design may need minor adjustments.

Look for clean, uniform material without clay lumps, ask for supplier test reports and have a lab test it for important structural work.
Does the choice affect cost?
Prices vary with transport distance and supplier. Compare delivered cost and quality together, not just the rate.
