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?
