A modular wall block is adapted for being assembled together with a number of like blocks in stacked courses to form a retaining wall. The wall block includes a front and rear, top and bottom, and opposing sides. A generally J-shaped anchor has a connecting end and an anchoring end integrally joined by a setback spacer. The connecting end is adapted for being inserted into the wall block to secure the anchor to the block. The anchoring end extends outwardly from one of the top and bottom of the wall block to engage one of the number of like blocks in an upper or lower course. The spacer locates the anchoring end a spaced distance from the rear of the block. The anchor secures the block in the retaining wall at a predetermined setback relative to like blocks in the upper or lower course.

A (modular wall block is adapted for being assembled together with a number of like blocks in stacked courses to form a retaining wall. The wall block includes a front face and rear, top and bottom, and opposing sides. A locking shear key extends outwardly from either of the top or bottom of the wall block, and is adapted for residing between respective adjacent sides of like blocks in an adjacent upper or lower course to anchor the wall block in position. A severable area is formed with the shear key for being removed to accommodate placement and orientation of the wall block between respective adjacent sides of like blocks in an adjacent upper or lower course.

A modular wall block is adapted for being assembled together with a number of other blocks in stacked courses to form a retaining wall. The wall block has a front and rear, top and bottom, and opposing sides. At least one of the opposing sides defines a generally L-shaped vertical slot. A course connector is received in the vertical slot, and includes first and second ends joined together by a setback spacer. The first end extends in an x-direction and a y-direction, and defines a generally L-shaped structure received in the L-shaped slot and restricting forward, rearward, and outward movement of the course connector. The second end of the course connector extends outwardly in a z-direction beyond one of the top and bottom of the wall block to engage one of the number of other blocks in an upper or lower course. The setback spacer locates the second end of the course connector a spaced distance from the first end to position the wall block in the retaining wall relative to the other blocks in the upper or lower course.

A modular construction block is adapted for being assembled together with a number of other blocks in stacked courses to form a wall. The construction block includes first and second opposing block faces, a top and bottom, and opposing ends. The first block face has a first plurality of vertical score lines. The second block face has a second plurality of vertical score lines. The first and second plurality of vertical score lines resemble respective mortar joints, whereby the assembled wall resembles a brick structure.

A modular wall block is adapted for being assembled together with a number of other blocks in stacked courses to form a retaining wall. The wall block has a front and rear, top and bottom, and opposing sides. The top and bottom define respective substantially planar stacking surfaces. A shear lug projects from one of the planar stacking surfaces of the top and bottom. A block-locating jut is formed with at least one of the opposing sides, and projects from the side at a point intermediate the top and bottom towards one of the planar stacking surfaces. The block-locating jut defines a base surface substantially coplaner with the stacking surface, and a lug-engaging shoulder adapted for engaging a shear lug of a wall block located in an adjacent stacked course.
