In the summer with the guys were apprentices at the brigade of experienced storekeepers. We went to work near Samara, where customers adore porous brick (it seems they make it there). Previously, it was considered to be junk material, which is only convenient to ditch. Local is completely different, especially the 38th. They unloaded it with a shaft, all the bricks are whole.
The terrain, it is understood, is not hot, but the local architects design the walls in 2 bricks of the standard variety (510 mm together) without any insulation. Indeed, they began to put, the insulation is simply impossible to stick. Even in jumpers under the windows. In terms of speed, warm ceramics seemed to me a record holder. The masters screamed us endlessly, so that they would sooner interfere with the solution and bring it to us. But with the amount of solution we were mistaken more than once, it did.
pros
durable (even without falling from a 10-meter height), it fits easily and quickly, eliminating the need for insulation
Minuses
difficult to calculate solution volume
