I think that is the special* type of sand required for concrete production.
* Concrete requires coarse grains, which are found in river beds and beaches. A lot of the worlds sand is in deserts, which has fine grains due to its age / years of tumbling.
- pvaldes 6y ago1) use fine sand to make tempered glass 2) break it 3) Now use those small pieces of broken glass as if they were coarse sand to make concrete. Or even better recicle all those old cracked car panes lying in the dumpster. Problem solved. Maybe you could even obtain cool semitransparent concrete, if you polish the finished stuff. I dunno. Would be cool stuff in any case.
