ABSTRACT:
Unique fired clay pillows are described which are useful for a variety of purposes. They have particular utility in structural applications when they are first rendered impervious, mixed with a hardenable binder, and then cast into a mold or form of desired size and configuration where the binder is hardened, thereby producing a consolidated pillow structure having a high degree of void space. The consolidated pillow structure is fire-resistant, weather-resistant, rot-proof, and exhibits good sound absorption and thermal insulation properties.
