Abstract

Disclosed are a fire-resistant ordinary ceramic batch and a fire-resistant product predominantly comprising a) at least one granular, fire-resistant, mineral, alkaline main component made of an MgO-based or MgO and CaO-based fire-resistant material that is based on at least one alkaline fire-resistant raw material, and b) at least one granular, fire-resistant, mineral, MgO-based, additional elasticator in the form of a forsterite material or a mixture forming forsterite material preferably as small molded articles, such as pellets or granulate that is comminuted from compacts. The small molded articles have a grain size ranging from 0.3 to 8 mm while being advantageously provided with a binder at an amount that elasticates the main component.
