Dick Leach from Albion College in Michigan developed
a number of castable mixtures that worked very well-
he had some that lasted for 20 years or so. A recipie
that he used and called "excellent" was as follows:
C/10 firing range(salt too) castable
PARTS MATERIAL
2.5 crushed corn cobs
2.0 clay
2.5 grog
0.5 alumina
1.0 cement(Portland)
Mix to "snowball" consistency; ram it up. 4" thick walls.
Any questions:
