Aluminium is a crucial material in the nuclear industry, valued for its reliability over long periods of irradiation. The manuscript focuses on validating aluminium neutron transport libraries. Validation experiments were performed on an aluminium block with a central hole. The block was assembled from smaller aluminium plates. The experiment involved activating samples at different positions and measuring the fast neutron spectrum in the energy range of 0.1 MeV-1.3 MeV by means of a hydrogen-filled proportional detector and in the energy range of 1 MeV-12 MeV using a stilbene scintillation detector. The dosimetric reactions studied for validation included 58Ni(n,p)58Co, 63Cu(n,gamma)64Cu, 181Ta(n,gamma)182Ta, 92Mo(n,p)92mNb, natTi(n,X)46Sc, and natTi(n,X)47Sc. All experimental data were compared with MCNP6.2 simulations using the ENDF/B-VIII.0, JEFF-3.3, and JENDL-5 neutron transport libraries. Activation cross sections were taken from the IRDFF-II library. Regarding activation reactions, the results are in good agreement with simulations, independent on the library. The JEFF-3.3 and ENDF/ B-VIII.0 fast neutron flux calculations are similar. All libraries provided results within two sigma uncertainty, except for JENDL-5 in the energy range of 1.8-3.4 MeV, and ENDF/B-VIII.0 (JEFF-3.3) in the region of 1.06-1.3 MeV.
