How to create nice corners when building a wall with these concrete blocks?

Home Improvement Asked on April 10, 2021

In a previous question, Why do many concrete blocks have this strange shape on either end?, I asked about the design of the concrete blocks having an I-shape at the ends.

That explains how to make a strong wall, but how does one go about using these strange-shaped bricks to make a 90 degree corner? Assume the bricks are positions such that the holes point upwards for rebar to be placed, won’t that make the strange I-shape visible in the corners?

Here are a couple of pictures from the garage I had built, showing the blocks Ecneral referenced.

You purchase corner blocks. Those are stretcher blocks for the middle of the wall, not corner blocks. A masonry supplier will have a variety of different shapes for particular purposes, one of which is corners (both full and half-blocks)

There are also special shapes for door/window openings (sash blocks and lintels), bond beam blocks for horizontal rebar placements, etc.

You might want to search on "CMU construction methods" (CMU is "concrete masonry unit" or the formal name of the concrete block.)

Here is one type of concrete block that will enable the construction of a smooth angular corner:enter image description here

When laying block for a wall it is best to start at each corner and work inwards. The corner's need to be interlaced; that is each row must be at right angles to the other for maximum stability and strength.

Use the smooth faced block for he corners and the other type (stretchers) for the intermediary section of wall.
