Jan 01 2019 · In recent years much research has focused on improving the performance of the refractory castables in severe service environments particularly in the steel and cement industries. Oxide nanoparticles such as TiO 2 21 Al 2 O 3 22 SiO 2 23 ZrO 2 24 etc. are used in the matrix of refractory castable formulations. Refractory concrete is an unshaped refractory material that is prepared by adding water or other liquids to refractory aggregates powders and cement and is used directly without calcination. Also known as refractory castable generally most of this material is constructed by pouring. So it is also called refractory castable.
