The inventive material can be used inside cement industry kilns in order to counteract the thermal and physico-chemical deformation that occurs inside the kilns. 5 The invention composition is based on a combination of a percentage by weight equal to or greater than about 10 of andalusite (AInSiO4 ), a percentage by weight equal to or greater than about 10 of silicon carbide (SiC) and a percentage by weight equal to or greater than about 5 of clay. Moreover, kaolinite (A14 [(OH)8 (SiO4)4]) can be used instead of andalusite in equal proportions. 10 The refractory material can be used to line the inside of the cement kilns in the calcination areas (2), in the kiln outlet (6) and in the coolers (7). rAm- AM A11R 0'2 v 7.0591' 7141/2 CD U0) F Figure 1
