Typical examples ~
Solid brickwork
T = thickness
Note: For practical reasons a standard one-brick dimension is given
for 240 minutes fire resistance. Theoretically a clay brick wall can
be 170 mm and a concrete or sand/lime brick wall 200 mm, finishes
excluded.
Solid concrete blocks of lightweight aggregate
T = thickness
Note: Finishes excluded

non-load bearing wall.
T (mm) 102.5 215 Concrete or sand/lime bricks.
Load bearing or non-load
bearing wall.
Fire resistance (minutes)

compressive strength.
T (mm) 75 100 140 Non-load bearing, 2.8†3.5 N/mm^2
compressive strength.
