Cement to fill speaker stands?


Maybe a stupid question, but I wonder if cement (the powder used for construction) can be used instead of sand to fill speaker stands? It is somewhat difficult to find silica or play sand (no gun shops in my country so forget about lead shot) where I live, so I asking you what you think about cement for this purpose.

Thanks!

There is an English product Atabites made of a very heavy metal. If your speakers are not shielded I would recommend to keep Atabites fill away from drivers at least 20cm.

Cement is OK and even better than playsend(playsend is too light IMO).
Use Caution padames, some cement mixes contain lime. If used in a metal stand you actually create a corrosive action, especially in high humidity conditions. In a wood stand the lime content will actally draw the natural oils from the wood and over a period of time will cause premature cracking, splitting, etc. Lime can be pretty nasty stuff.
