| Abstract |
| The P. C. E. value of Pachegaon clay is 1.550'C (Orton
cone 20-23) and hence is suitable for making lozo heat duty
fireclay brick~. The addition of grog increases porosity, reduces
firing shrinkagP, and improves spalling resistance. There is no
shrinkage on reheat. It is also seen that with bond between 40
and 60%, there is no change in fire shrinkage. This is probably
due to a part on the bond simply acting as a filler in the
pore spaces.
