Simplified equations for single leaf wall with blocks laid flat
Provides a worked example showing how to calculate mass per unit area for a single leaf wall constructed with blocks laid flat, using specific dimensions and material properties.
Example of single leaf wall, blocks laid flat
d = 0.010 m
T = 0.215 m
L = 0.450 m
H = 0.110 m
V = 0 m³
pm = 1800 kg/m³
No surface finish
Mass per unit area = (20.20 x MB) + 43.00 kg/m²
Substituting for MB in this formula gives the following values:
Block mass MB (kg) Mass per unit area (kg/m²)
