Investigation of influence of non-equilibrium initial states and structural disorder on characteristics of anomalous slow non-equilibrium critical behavior of three-dimensional Ising model is carried out. The unique ageing properties and violations of the equilibrium fluctuation-dissipation theorem are observed for considered pure and disordered systems which were prepared in high-temperature initial state and then quenched in their critical points. The heat-bath algorithm description of ageing properties in non-equilibrium critical behavior of three-dimensional Ising model with spin concentrations p = 1.0, p = 0.8, and 0.6 is realized. On the base of analysis of such two-time quantities as autocorrelation function and dynamical susceptibility were demonstrated the ageing effects and were calculated asymptotic values of universal fluctuation-dissipation ratio in these systems. It was shown that the presence of defects leads to aging gain.
