Abstract

Salah satu aditif pada beton adalah Bestmittel dimana termasuk bahan tambah golongan type E (water reducing and accelerating admixture) yang berfungsi mempercepat pengerasan, mengurangi pemakaian air dan meningkatkan workability. Tujuan penelitian ini untuk mengetahui pengaruh Bestmittel terhadap kuat tekan beton dan mengetahui persentase kenaikan kuat tekan beton normal terhadap kuat tekan beton Bestmittel dengan nilai koefisien menggunakan Peraturan Beton Indonesia (PBI 1971). Benda uji berbentuk silinder dan jumlah 30 buah, variasi umur pengujian beton yaitu 3 hari, 7 hari, 14 hari, 21 hari, dan 28 hari. Variasi dosis penambahan Bestmittel yang digunakan 0,4% dari jumlah semen, serta pengurangan jumlah air 10%. Hasil pengujian kuat tekan beton normal pada umur 28 hari sebesar 25,653 MPa dan kuat tekan beton Bestmittel sebesar 29,615 MPa. Persentase kuat tekan beton Bestmittel umur 14 hari sudah mencapai sebesar 96%. Berdasarkan nilai Koefesian PBI 1971 bahwa kuat tekan beton mencapai 100% jika umur beton 28 hari, sedangkan Beton menggunakan bahan tambah Bestmittel pada umur 21 hari dan 28 hari berturut-turut 105% dan 115%. Hal ini membuktikan bahwa dengan penambahan aditif Bestmittel 0,4% dan pengurangan jumlah air 10% meningkatkan kuat tekan beton, dan mempercepat proses pengerasan beton di umur muda dengan arti bahwa Bestmittel memiliki pengaruh yang signifikan terhadap kuat tekan beton.

Abstract

Concrete is one of the main construction materials widely used in infrastructure development due to its high compressive strength and good durability. However, achieving optimum compressive strength in concrete requires a relatively long curing time, around 28 days. To overcome this issue, additives such as Bestmittel are used, which function to accelerate the hardening process and increase the compressive strength of concrete at an early age. This study aims to determine the effect of adding 0.5% Bestmittel on the compressive strength of concrete at curing ages of 3, 5, 7, 15, and 28 days. The specimens used were cylindrical with a diameter of 15 cm and a height of 30 cm, and three samples were prepared for each variation. Based on the test results, the compressive strength of normal concrete at 28 days was 26.31 MPa, while the compressive strength of concrete with Bestmittel at 3, 5, 7, 15, and 28 days was 20.47 MPa, 25.65 MPa, 25.94 MPa, 27.63 MPa, and 32.16 MPa, respectively. At 7 days, concrete with Bestmittel almost reached the strength of normal concrete at 28 days, with a percentage of 98.58%, and at 15 and 28 days it exceeded the strength of normal concrete with percentages of 105.03% and 122.24%, respectively. The results show that the addition of 0.5% Bestmittel is effective in accelerating early-age strength gain, making it highly suitable for use in construction projects that require high strength within a relatively short time.
