Engineering resilience with precast monolithic refractory
Precast refractory ceramic shapes have had well‐known benefits over other refrac- tory lining methods consistent and controlled manufacturing processes with faster turnaround than traditional cast‐in‐place monolithic refractories reduced labor cost It is defined as the ratio of its pores volume to its total volume. Porosity is an important property of refractories because it affects many other features such as resistance to abrasion thermal conductivity. In general a good refractory must have low porosity.

A refractory material is one that retains its strength at high temperatures. ASTM C71 defines refractories as non-metallic materials having those chemical and physical properties that make them applicable for structures or as components of systems that are exposed to environments above 1 000 °F (811 K 538 °C)". Refractory materials must be chemically and physically stable In The Efficient Use of Energy (Second Edition) 1982. Refractory Parts (see Chapter 17) Walls roof and hearth are generally constructed from refractory materials either in brick form or monolithic construction using castable or plastic (mouldable) materials.
