In this paper the experimental results of developing refractory monolithics containing pumice,
expanded perlite, kieselguhr and Portland cement are presented. Using Andreasen Equation, three different
aggregate grads have been tried to obtain N class insulating monolithic refractory composition to comply with
ASTM standards. The results of analysis of pumice, perlite and kieselguhr are given. Bulk densities, linear
changes after drying and firing (925°C) and cold crushing strengths have also been determined on the samples
prepared according to ASTM standards. As the best values, the bulk density after drying was 0.94 g/cm³ and
the linear change after 925°C was calculated as -1.7 %, which are given as 0.88 g/cm³ and -1.5 % respectively
in related ASTM standard.
