AAC slab is a component of precast floor slabs commonly used in buildings. As a new product, the performance of AAC must be examined to ensure that its slabs meet the requirements of the applicable standards. Those requirements are reviewed in terms of strength and stiffness. This research was conducted experimentally using 3 test objects of AAC slabs size: 2000x600x125 mm with two-point load method, in addition to testing physical and mechanical characteristics of AAC material in the laboratory as input for numerical modeling. AAC samples were taken by core-drilling 30 samples of panels, then 6 samples of cubes were taken by cutting the plates when they came out of the Autoclave, and 3 cylindrical samples with a diameter of 150 mm x 300 mm. The samples were then tested in the laboratory to determine the parameters of the mechanical properties such as a stress-strain graph, compressive strength, modulus of elasticity, and maximum strain. Physical properties such as specific gravity and water content were also tested. All samples were taken from the same place. Numerical analysis was carried out using ANSYS R3 2019 to obtain slab vibration parameters. The result showed that AAC has an average maximum principal stress area load of 4.48 kN/m 2 , and meets the requirement to be used in the office, school, and residential houses. Furthermore, this study also found a natural frequency can be a standard of comfort building criteria.
