Is sintering insulation brick good or concrete porous brick good?
Strength and fastness are, of course, porous bricks.
Thermal insulation brick is functional material, it is better than porous brick in thermal insulation. At the same time, the internal heat preservation material, so the overall cost is more, the hole brick should be higher.
As with the expansion screw, it depends on what to connect, and go in is no problem, the key is that the carrying capacity is not very high, if you do steel support, pull and so on, it is recommended to use concrete.
