What causes holes in bricks?

So having holes in them has the added benefit of cutting down on their weight and thus their cost to transport. And as brick have an incredibly high compressive strength (compared to the mortar that holds them together and even most common mixes of concrete), the holes don't really detract from their structural value.

.

Similarly, it is asked, why are there holes in bricks?

Most important, the holes allow the masonry structure to be built more securely. The brick is turned during construction (you won't see the holes on the finished product) allowing mortar to fall inside. These holes, filled with mortar provide a "keyway," locking one brick to the next.

One may also ask, what are holes in bricks called? Bricks have core holes or recesses (called “frogs”) for several reasons. The most important is a principle called “keying in.” Core Holes Frog Brick.
