Modular construction of load-bearing structures from reusable load-bearing elements

A modular building system comprising:

• a first reusable load-bearing component comprising a first cementitious composition and having at least one first interlock feature defining either a protrusion or a recess and at least one first aperture defined through a first wall;
• a second reusable load-bearing component comprising a second cementitious composition and having at least one second interlock feature complementary to the first interlock feature having the other of the protrusion or the recess and at least one second aperture defined through a second wall, wherein the first wall and the second wall are adjacent to one another so that the at least one first interlock feature seats against the second interlock feature;
• and
• a fastener disposed in the first aperture and the second aperture that secures the first reusable load-bearing component and the second reusable load bearing component together without any adhesive or mortar.

A load-bearing structure comprising:

• a plurality of first reusable load-bearing components comprising a first cementitious composition and having at least one first interlock feature defining either a protrusion or a recess and at least one first aperture defined through a first wall;
• a plurality of second reusable load-bearing components comprising a second cementitious composition and having at least one second interlock feature complementary to the first interlock feature having the other of the protrusion or the recess and at least one second aperture defined through a second wall, wherein the first wall and the second wall are adjacent to one another so that the at least one first interlock feature seats against the second interlock feature;
• and
• a plurality of fasteners respectively disposed in the first aperture and the second aperture that secures each of the first reusable load-bearing component and the second reusable load bearing components together without any adhesive or mortar.
