Refractory Concretes (Monolithic Refractories)
Monolithic refractories, or unshaped refractories, are made from almost same raw materials as firebricks. The distinguishable feature is that the method of preparation does not involve forming or firing at the manufacturing plant. A general definition includes batches or mixtures consisting of additives and binders, prepared for direct use either in state of delivery or after adding suited liquids. The final mix may contain metallic, organic, or ceramic fibers [38, 39].
