The main purpose of the present paper is about characterizing properties of the perfect uid space-time admits the gradient Ricci- Bourguignon soliton. This gives some results about stability of the energy momentum tensor and also under some conditions pursues that a perfect uid space-time is Ricci symmetric. As an special case, when a perfect uid space-time equipped with the Ricci-Bourguignon soliton which has Ricci biconformal vector field, we show that the metric of this space is Einstein.
