Abstract

The purpose of this research was to determine the effect of water temperature on the concrete mixture using water with a temperature of 27ºC, 37ºC, 47ºC in the concrete mixture to value structural concrete compressive strength. This research uses cylindrical specimens with a size of 150 mm diameter and 300 mm in height. The study involved testing compressive strength at the age of 3 days, 7 days, 14 days, and 28 days. Based on the test results, the compressive strength values obtained at 3 days of age with a water temperature of 27ºC to 14.132 MPa, 37ºC to 19.496 MPa, 47ºC to 21.554 MPa. The results of testing at the age of 7 days obtained compressive strength with a water temperature of 27ºC to 19.817 MPa, at 37ºC to 22.471 MPa, at 47ºC to 25.822 MPa. The results of testing at the age of 14 days with a water temperature of 27ºC to 27.090 MPa, at 37ºC to 28.556 MPa, at 47ºC to 28.973 MPa. The results of the test at 28 days the compressive strength of concrete with a water temperature of 27ºC to 30.246, 37ºC to 31.250 MPa, 47ºC to 32.149 MPa. The normal water temperature of 27ºC is used as a reference to see the effect on the value of concrete compressive strength. Based on this study, the use of water in concrete mixtures with temperatures of 37ºC and 45ºC affects the compressive strength of concrete.

Abstract

Concrete as the main construction material has an important role in determining the strength and reliability of a construction project. The quality of concrete is influenced by the properties of its constituent materials, such as gravel, sand, cement and water. Testing the compressive strength of concrete is an important step to assess its quality and ensure it meets construction standards. Although previous research has compared the compressive strength of concrete and changes in aggregate volume, this research still covers limited dimensional variations and further exploration of aggregate dimensional variations is needed. This laboratory study used a conventional concrete design according to SNI 03-2834-2000, with compressive strength tests carried out at the Material Testing Laboratory, part of the Civil Engineering Department at Politeknik Negeri Banyuwangi Banyuwangi. The experimental results recorded in the fourth chapter show that at 7, 14, and 28 days, type AG 10 has the highest compressive resistance value, statistically significant mean value, and also shows that type AG 40 has the lowest compressive strength value. Therefore, it can be concluded that the smaller the size variation of coarse aggregate, the higher the compressive strength of concrete. These findings provide a comprehensive picture of the compressive strength characteristics of concrete with varying coarse aggregate sizes.

Abstract

Desain campuran beton di Indonesia mengacu pada standar nasional yang telah mengalami perubahan, dari 03 2834:2000, SNI 7656-2012, hingga AHSP 2023. Penelitian ini bertujuan membandingkan efisiensi dan mutu beton yang dihasilkan dari ketiga standar tersebut. Beton, sebagai material konstruksi utama, memiliki kualitas yang bergantung pada komposisi campurannya. Ketiga standar ini mengatur proporsi campuran beton dengan pendekatan berbeda, yang dapat mempengaruhi jumlah semen dan kuat tekan. Menggunakan metode eksperimen komparatif, penelitian ini membuat sampel beton silinder berdasarkan ketiga standar, kemudian menguji dan membandingkan hasilnya, terutama dalam hal kuat tekan beton. Hasil pengujian pada umur 28 hari menunjukkan bahwa 03 2834:2000 menghasilkan kuat tekan tertinggi (27,956 MPa), SNI 7656-2012 menunjukkan konsistensi terbaik dengan kuat tekan 27,552 MPa dan deviasi standar terendah (2,93%), sementara AHSP 2023 menghasilkan kuat tekan yang lebih rendah namun paling mendekati target 21 MPa (24,590 MPa). Ketiga metode mencapai kuat tekan di atas 21 MPa pada umur 28 hari, memenuhi syarat mutu beton sedang dengan masing-masing keunggulan berbeda
