Dear Friends,

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 =
1.80, SO3 0.80, LOI 4.50.=20
