Technical Examples
  1. The structural block made from friable sandstone of the present invention includes a friable sandstone block quarried from a friable sandstone deposit in which the friable sandstone has an inherent structure providing strength, and cement disposed within the inherent structure to lock the inherent structure in place. In another embodiment, a confining jacket can be disposed about a friable sandstone block to lock the inherent structure in place. If desired, the cement or confining jacket can include a coloring agent such as a dye or pigment for aesthetic effect. The method for making structural block from friable sandstone of the present invention comprises determining whether the friable sandstone is quarriable, treating the friable sandstone in place if the friable sandstone is not quarriable, quarrying the friable sandstone into friable sandstone blocks, and finishing the friable sandstone blocks into structural blocks.
