Effects of Elevated Temperatures On The Performance of Heat Resistant Mortars

Fire has long been a major hazard in our lives. To control the aftermath effects of these fire accidents, flame retardant technology is becoming increasingly important. Various refractory materials are already in use but their life span and economy are questionable. Many refractory concretes are developed but refractory mortars are rarely addressed. Therefore, developing refractory mortars are of prime importance for various industrial applications. In this study, ten different refractory cement mortars are prepared along with 1:3 ratio of cement mortar mix as control and heated in the furnace for elevated temperature regimes from 110°C to 800°C with a soaking period of one hour for each temperature range. Also the insulation capacity and cracking potential of the same mixes were tested for various other applications. The mechanisms for the behaviour of each refractory mix at elevated temperature are discussed elaborately in this paper.
