For a finite or an infinite set X, let 2 X be the power set of X. A class of simple graph, called strong Boolean graph, is defined on the vertex set 2 X \ {X, ∅}, with M adjacent to N if M ∩ N = ∅. In this paper, we characterize the annihilating-ideal graphs AG(R) that are blow-ups of strong Boolean graphs, complemented graphs and preatomic graphs respectively. In particular, for a commutative ring R such that AG(R) has a maximum clique S with 3 ≤ |V (S)| ≤ ∞, we prove that AG(R) is a blow-up
