[GSBN] use of ashes in clay plasters and/or floors

[Evgen Shirokov]

Hello,

we add wood ash in clay (+shell) plaster for SB walls finishing, as well as masonary ovens - it works well. 
But if say about heat insolation - normally it means use of coal ash. Somtimes it's problem - becouse of hight level nuclear radiation.
