Claims: I claim:

1. An electrical insulation grade polymer containing concrete comprising a polymer and a silane treated crushed electrical insulation grade porcelain aggregate.

2. The electrical insulation grade polymer concrete of claim 1 wherein said silane is of the formula R'Si(OR).sub.3 wherein R is alkyl or alkoxyalkyl and R' is alkyl, alkylene, or amino, epoxy or mercapto substituted alkyl.

3. The electrical insulation grade polymer concrete of claim 2 wherein R is lower alkyl and R' is epoxy substituted alkyl.

4. The electrical insulation grade polymer containing concrete of claim 3 wherein said silane is .beta.-(3,4-epoxycyclohexyl) ethyltrimethoxysilane.

5. The electrical insulation grade polymer concrete of claim 1, wherein said polymer is 10 to 20% of the total weight of the polymer and aggregate.

6. A method of preparing an electrical insulation grade polymer concrete which comprises contacting a crushed electrical insulation grade porcelain aggregate with a silane, combining said silane treated aggregate with a resin, and thereafter curing the resulting mixture.

7. The method of claim 6, wherein said silane is employed in an amount of about 0.05-2.0 weight percent based on the weight of said aggregate and wherein said resin is 10-20% of the combined weight of the resin and aggregate.

8. The method of claim 6 wherein said silane is of the formula R'Si(OR).sub.3 wherein R is alkyl or alkoxyalkyl and R' is alkyl, alkylene, or amino, epoxy or mercapto substituted alkyl.

9. The method of claim 8 wherein R is lower alkyl and R' is epoxy substituted alkyl.

10. The method of claim 9 wherein said silane is .beta.-(3,4-epoxycyclohexyl) ethyltrimethoxysilane.
