ABSTRACT:
Load bearing insulation for the base of liquefied gas storage tanks comprises a plurality of courses of cellular glass blocks having horizontal cut faces with open hemispherical cells thereon. A layer of irreversably compressible inorganic particulate material, such as vermiculite, is applied by rolling or screeding on and between each course of cellular glass blocks. The vermiculite particles penetrate the plurality of open hemispherical cells to completely fill the cells. During the application of the vermiculite capping layer, particles are precompressed to bring the vermiculite particles into intimate contact with the open cells. The precompression of the vermiculite capping layer mechanically adheres the particles to the cellular glass block cut face to thus form an irreversibly compressible capping layer on and in between the cellular glass blocks having a compressive strength in the range between about 90 p.s.i. to 180 p.s.i.
