Dataset for: Properties of the Transition Region in 3D Printed Functionally Graded Concrete through Near Nozzle Binder-Aggregate Mixing (NNBAM)

This dataset contains the experimental data supporting the study “Properties of the Transition Region in 3D Printed Functionally Graded Concrete through Near Nozzle Binder-Aggregate Mixing (NNBAM)”. The dataset includes measurements from both cast specimens and specimens extracted from a 3D printed element with a gradual transition from lightweight mortar to natural sand mortar.Recorded properties include density, water absorption, fresh state rheological parameters, and mechanical properties such as flexural strength, compressive strength, and elastic modulus.The data enable analysis of material gradation and property evolution in functionally graded 3D printed concrete.
