Abstract: A unibody structural frame for an interlocking structural block, an interlocking structural block, and a system of interlocking structural blocks useful for the manufacture of structures, columns, and beams.

Abstract: Construction materials intended for use as structural elements, such as structural blocks, used in the construction of buildings and civil engineering structures. The blocks can comprise hemp hurd and fibers, flax fiber, hydraulic lime and hydrated lime. In one aspect, the blocks may comprise a body shape configured so as to allow it to interlock with other blocks in the construction of a structure. In another aspect, the blocks may be adapted to incorporate tensioning means. Methods for manufacturing the blocks and structures comprising such materials and methods for building such structures are also disclosed.
