In this paper we have investigated two fluid axially symmetric cosmological models in $f(R, T)$ theory of gravitation. To get the deterministic model, we have assumed a supplementary condition $H_3=k H_1$, where $H_1$ and $H_3$ are Hubble parameters and $k$ is constant. Two-fluid model in $f(R, T)$ theory of gravitation, one fluid represents the matter content of the universe and another fluid is chosen to model the cosmic microwave background radiation. Some geometric aspects of the model are also discussed.

“…After the cosmological constant was introduced into general relativity, many cosmologists believe that the simplest candidate for the dark energy is the cosmological constant or vacuum energy. The cosmological constant Λ and phantom fields are violating weak energy conditions 0 p ρ + > [13]. On the other hand this cosmological constant always suffers from the theoretical problems -'fine-tuning' and 'cosmic coincidence' [18].…”
