Press hole rate cent: solid brick (do not have hole or the brick with hole rate less than 25%), porous brick (hole rate is equal to or more than 25%), the dimension of hole is small and the brick with much quantity, often use at bearing place, intensity grade is taller. Hollow brick (hole rate is equal to or greater than 40%, the size of the hole is large and the number of bricks, often used for non-bearing parts, strength grade is low).
Solid brick and porous brick are used at bearing structural wall body more, hollow brick is used at blame bearing structural wall body more.
