Dear Friends,
Recently there was an inquiry about the composition of Rice Ash.
The following was published in "Tile and Brick International'" 4/2003, =
p258 in an article by Dr. S. H. Tantawi of the Building Research =
Institute, Cairo, Egypt.
Rice Husk Ash. (RHS)
SiO2 86.90, Al2O3 0,10, Fe203 0.03, CaO 3.20, MgO 2.60, Na2O 0.16, K2O =

I hope this is of use to those who are interested in such topics.
