Dear All,
A very simple question to you all.
What is the need to put blinding at the footing of a structure. Why can the beam not just sit directly on the compacted ground?

Sometimes where the required bearing pressure is achieved at varying levels, it is more practical to replace the soft material with low strength concrete than to lower the actual reinforced pad. This material in the overexcavated area is often called blinding concrete.
Another use for blinding concrete is under a continuous slab or mat foundation which is required to be waterproofed. The waterproofing is done on a blinding layer, then the mat is built.

In India, it was interesting in that they specified 6 inches of sand below the mudmat - why? It got damaged during placement of the mudmat - with the workers disturbing it and all. Stupid - but I've also seen this in Indonesia as well . . . Go figure . . . (wished I didn't have to).

We call it mud-slab.
