| Summary: | Reinforced concrete structures are typically built in three steps: installing steel reinforcement, assembling formwork, and casting concrete. These steps are carried out sequentially, thus taking time and delaying the project’s operation, leading to reduced economic efficiency. Researching solutions to shorten construction time will contribute to bringing about clear economic efficiency. The study conducted experiments and numerical simulations of cylindrical specimens with a diameter of 250 mm , manufactured using 45 MPa concrete, casting tubulars with thicknesses of 15 mm, 20 mm, and 25 mm , respectively, as formwork, leaving the concrete filled
with self-compacting concrete with a strength of 30 MPa . The specimens were tested and simulated in two cases: compression of the total cross-section and compression of the concrete-filled section. The research results show that, in addition to determining the optimal tubular thickness of 15 mm , determining the correlation between the concrete-filled and tubular concrete strength of 1.5 times allows us to use the same concrete production technology to save costs and simplify production. |
