Frequently Asked Questions
1. Why is CEN-Standard sand necessary for cement testing?
To test the strength of cement fairly, the sand used in the mortar mix must be identical every time. CEN-Standard sand provides this constant, eliminating variables so that only the performance of the cement is measured.
2. How long can Normensand be stored before use?
When stored in its original, unopened packaging in a dry environment, Normensand has an indefinite shelf life as it is a stable mineral product. However, it must be kept free from moisture to ensure accurate weighing and mixing.
3. Does Normensand provide sand for specialized geotechnical research?
Yes, in addition to standard testing sands, Normensand offers various natural and synthetic sands with specific grain shapes (round vs. angular) to simulate different environmental soil conditions for university and engineering research.
4. Is the sand pre-weighted in the bags?
Yes, CEN-Standard sand is typically supplied in precisely weighted 1350g bags, which is the exact amount required for a single standard batch of mortar according to the EN 196-1 testing protocol.
