Abstract Of The Disclosure A block of concrete or the like for use in constructing a mortarless wall is provided which includes a spaced parallel pair of upright sidewalls having flat bottoms and tops and bearing integral block interlocking connectors on their opposite ends. The sidewalls are integrally connected to one or more transverse webs extending from the bottom of the sidewalls to above the tops thereof. Parallel slits may divide the upper end of the web into knock-off portions for installation of reinforcing bars. Each web has a central concavity in the upper end of at least one opposite side thereof, which concavity slope down into a complimentary central bottom convexity. The web tapers in thickness from bottom to top. The concavity and convexity can be triangular, dish-shaped, rectangular, etc. The webs define cells in the block when a number of the blocks are vertically stacked in staggered array to form a wall. The webs make point or line contact with each other to interlock and prevent horizontal displacement, while presenting staggered cells and maximum surface area for adhesion to reinforcing concrete poured into the cells. The block is inexpensive, durable, strong and easy to use.
