Kajian Eksperimen dengan Penambahan Serat Baja Dramix 3D pada Beton High-Performance Concrete (HPC)

Abstract

When considering the durability of conventional concrete for use in high-rise buildings and structures that are vulnerable to explosions, impacts, or earthquakes, its strength and brittleness are considered. Previous studies have shown that the use of high-performance concrete or HPC (High-Performance Concrete) can improve the performance of concrete structures. The analytical procedures and design guidelines required for this concrete require material and structural examination. The results of experimental tests conducted on the literature using high-quality concrete verify the model, namely the compressive strength, splitting tensile strength, and modulus of elasticity of concrete. In this study, HPC concrete with the addition of Dramix 3D steel fibers was evaluated analytically with variations in the addition of 0%, 3%, 6%, and 9% for concrete ages of 7 days, 14 days, and 28 days for the HPC concrete compressive strength test and concrete age of 28 days for the concrete splitting tensile strength test. In the study, the results obtained the maximum compressive strength of HPC concrete is 94.776 MPa, the maximum splitting tensile strength of HPC concrete is 6.599 MPa, and the maximum modulus of elasticity of HPC concrete is 45.756 GPa. The results of the analysis indicate that the addition of Dramix 3D steel fiber can provide an effect on increasing the compressive strength, splitting tensile strength, and modulus of elasticity of concrete.
