The large top-quark pair-production (ttbar) cross-section at the LHC provides a unique opportunity to perform stringent tests of the Standard Model (SM). The analysis presented here is performed in the fully hadronic decay mode of the ttbar system. This channel has the largest branching ratio ($\sim 46$%) and it is the only one allowing kinematically reconstructing the ttbar system. The measurement is performed using the full 2015 and 2016 dataset collected by the ATLAS at 13 TeV, corresponding to L=36.1 fb-1. The differential cross-sections are compared to the most updated Monte Carlos and the higher-order calculations.
