This is a very simple question. The difference between two nouns is very simple. A common noun is a noun that denotes all the members of a class. But a concrete noun is also the same but for one difference. It is something you can feel for real. For example, ice cream is a common noun and a concrete noun. It is a concrete noun because you can taste it and feel it by yourself. Where as bottle which is also a common noun is not a concrete noun because you cannot feel it by your five senses.
A concrete noun is a noun that you cal feel with your five senses. This is the basic difference between a common noun and a concrete noun.
