  In this paper, we investigate cosmological consequences of a scenario for
recently reported accelerated expansion of the Universe, in which the
generalized Chaplygin gas (GCG) along with the baryonic matter are responsible
for this observed phenomenon. In the present model, we employ an isotropic and
homogeneous FLRW space time in the framework of $f(R,T)$ theory of gravity. In
$f(R,T)$ gravity, the conservation of energy-momentum tensor (EMT) leads to a
constraint equation which enforces us to use some specific forms of type
$f(R,T)=g(R)+h(T)$. In this work we choose $g(R)=R$. We consider three classes
of Chaplygin gas models which include three different forms of $f(R,T)$
function; those models which employ the standard Chaplygin gas (SCG), models
which use GCG in the high pressure regimes and finally, the third case is
devoted to investigating high density regimes in the presence of GCG.
