Perbedaan Dimensi Benda Uji Terhadap Kuat Tekan Beton

AbstractConcrete is one of the most widely used construction materials in various types of buildings and infrastructure. One of the critical factors in the quality of concrete is its compressive strength, which is measured through testing using cube- or cylinder-shaped specimens. Although testing standards have been established, the test results between these two specimen shapes often show significant differences. Therefore, this study aims to analyze the influence of specimen dimensions and shapes on the results of concrete compressive strength tests. The research was conducted at the Foundation Construction, Concrete, and Road Paving Laboratory at the Aceh Barat State Community Academy, using materials such as Andalas Portland cement, concrete sand, gravel, and water from the laboratory. The tests were performed according to SNI methods on cube and cylinder specimens at different concrete ages (7, 14, and 28 days). The results showed that the average compressive strength of both cylinder and cube samples increased with the age of the concrete. At 28 days, the average compressive strength of the cylinder was 17.243 MPa, while the cube reached 20.821 MPa. The ratio between the compressive strengths of the cylinder and the cube (f'c/f'ck) ranged from 0.825 to 0.837, indicating that the cylinder's compressive strength was about 83% of the cube's. The difference in compressive strength between the cylinder and cube specimens is influenced by stress distribution during testing, which is affected by the shape and dimensions of the specimens. Meanwhile, the compressive strength ratio between these two specimen shapes remained stable across different concrete ages, suggesting that the difference in specimen shape consistently affects the compressive strength test results.Keywords: Specimen dimensions, Compressive strength, Cube, Cylinder AbstrakBeton merupakan salah satu bahan konstruksi yang paling sering digunakan dalam berbagai jenis bangunan dan infrastruktur.

AbstractConcrete is one of the most widely used construction materials in various types of buildings and infrastructure. One of the critical factors in the quality of concrete is its compressive strength, which is measured through testing using cube- or cylinder-shaped specimens. Although testing standards have been established, the test results between these two specimen shapes often show significant differences. Therefore, this study aims to analyze the influence of specimen dimensions and shapes on the results of concrete compressive strength tests. The research was conducted at the Foundation Construction, Concrete, and Road Paving Laboratory at the Aceh Barat State Community Academy, using materials such as Andalas Portland cement, concrete sand, gravel, and water from the laboratory. The tests were performed according to SNI methods on cube and cylinder specimens at different concrete ages (7, 14, and 28 days). The results showed that the average compressive strength of both cylinder and cube samples increased with the age of the concrete. At 28 days, the average compressive strength of the cylinder was 17.243 MPa, while the cube reached 20.821 MPa.
