<p>A new method of preparing a fire-resistant sheet formed product is disclosed involving the following steps: (1) grinding together a particulate inorganic material selected from the group consisting of crystallized blistered glass, crushed cement clinkers and crushed blast furnace slags, a hydraulic binder and from 10 to 2% by weight of an organic thermosetting binder in a ball mill until the particulate inorganic material has sufficiently disintegrated and the particulate inorganic material, the hydraulic binder, and the organic thermosetting binder are homogeneously distributed to form a dry mixture of particles; (2) subjecting the dry mixture of particles to heat treatment, under pressure, to consolidate and bond the dry particles into a unitary structure to form a sheet; and (3) after release of pressure, treating the sheet with water to set and cure the hydraulic binder.</p> |
