Is กรวดทราย a good term to use for "sharp sand" ?

if by sharp sand you mean gravel /coarse sand , then yes it probably is.

If you mean sand with angular granules, I don't think it would be the right term. Gravel has a larger grain size and, by definition, is rounded to some extent.

An angular-grained, jagged sand, not rounded like beach sand. It is often recommended (in large quantities) as an amendment to loosen clay soil (along with compost); or to mix with sphagnum peat moss to create potting or starting medium.

It is also called builder's sand, although the two terms are not technically interchangable (sharp sand has a wider variety of grain sizes; builder's sand is mostly meidum to coarse grained.)

Where purchased, it should be free of clay, loam or other particles. If using it for potting or starting medium, you may want to rinse it, using a piece of fine screen to remove any sediment or other particles.

You certainly know your sand, soundman. (Sandman?)

The outfits that sell sand around here refer to Number 1 and Number 2 sand, corresponding to round and fine. Which is which I forget!
