Do you know differenence between design mix and nominal
mix?

Answer Posted / pandey u. p.

The volume based proportion of mix like 1:2:4, 1:1.5:3 and
1:1:2 are the nominal mix.
When ever pre design strength of mortor is required then we
should go for design mix which is based on different
proportion of material by weight and several material tests
to obtained required strength by trial and error method.

5. Two long boundary walls run parallel to each other at a center to center distance of 1 meter apart. The width and height of the first wall are 0.30 m and 2.5m respectively. While those of the second are respectively 0.18m and 3.5m. Plot the distribution of vertical stress intensity due to walls on a horizontal plane, 1m below ground level. The walls have negligible depth of foundation and are made of brick masonry (y = 19.2 kN/m cu)
