We extend the work of two-loop correction in the mean-field potential to study the thermodynamical properties of quark–gluon plasma (QGP). In the study,we look forward to determine bulk thermodynamic properties like pressure, entropy density, specific heat, quark number density, quark number fluctuations and speed of sound. The determinations are shown in figures and the figures are found almost similarly enhanced to our earlier results of one-loop correction. It means that the model with the inclusion of two-loop corrections can provide the entire thermodynamic information about the phase structure of QCD and the parameter used in the loop correction plays a pivotal role in forming stable droplets having less effect to calculate all the thermodynamical parameters. Still,the result can be considered in presenting QGP phase structure as it shows its representation within the range of standard thermodynamic properties and enhance the energy density and pressure from the lattice result.
