A concrete block includes first, second, third, fourth, fifth, and sixth planar faces. The first and second faces are generally parallel, and the distance between the first and second faces define a thickness of the first block; the third and fourth faces are parallel to each other and perpendicular to the first and second faces; the fifth face is perpendicular to the first, second, third, and fourth faces; the sixth face: extends perpendicular to the third face; extends toward the fourth face and ends at a non-planar remainder section; is parallel to the fifth face; is contained in a plane that intersects a plane containing the third face; and a distance from the intersection to the remainder section is at least as long as the thickness of the first block; and the remainder section extends between the sixth face and the fourth face and has a shape such that when a second block of the same construction as the first block has its remainder section engaged against the remainder section of first block, the remainder sections of the first and second blocks mate.

A construction module for constructing a structure, including an elongate member having a substantially L-shaped cross-section provided with connecting portions arranged to detachably attach with connecting portions on second and further construction modules, to form structure. A temporary structure can be formed from two or more of the construction modules. The structure may be temporary, semi-permanent or permanent.

A set of interlocking blocks consists a plurality of first blocks and a plurality of second blocks capable of forming kinematic interlock. Each of the first blocks and second blocks comprise at least one male joint and female joint for mating with its counterpart. The motion of the first blocks and second blocks are constrained by joints. Subsequent first blocks and/or second blocks reinforce and immobilize prior first blocks and/or second blocks. Assembly of an interlock structure consisting the set of interlocking blocks may be performed via translation motions.

A concrete building block includes indicators along each end to assist in aligning a pin placed in the block with a channel in a like block in a course below as a wall is being constructed.

A log wall construction including a plurality of log blocks, each having a substantially same height-dimension and laid next to each other to form a log block row having a log block row length. Log blocks next to each other have at least one pair of adjacent curved surfaces for each pair of log blocks next to each other. A second log block row of the plurality of log blocks laid next to each other to form the second log block row having a second log block row length and being located on top of the first log block row. A stringer located between the log block row and the second log block row and separating each log block row from each other log block row. The stringer extends substantially an entire distance equivalent to both the log block row length and the second log block row length.
