What it is
Construction sand can be natural river sand or manufactured sand (M-sand and P-sand) made by crushing rock. It should be clean and well graded, without clay, silt or salt.
Types and key points
- M-sand: for concrete and masonry
- P-sand: finer, for plaster
- River sand: scarce and regulated in Tamil Nadu
- Sea sand is never used: its salt rusts steel
Why it matters
Dirty or salty sand weakens concrete and makes plaster crack and bloom. A simple silt test on site catches bad sand.
How Elamentt handles it
We use M-sand and P-sand from checked sources; quantities are counted by the 100 cft unit as sold in Chennai.
