Abstract

fetched live from OpenAlex

Kuat tekan beton dipengaruhi oleh unsur-unsur pembentuk beton, salah satunya adalah air yang berfungsi sebagai pemicu proses kimiawi semen sebagai bahan perekat dan melumasi agregat supaya mudah dikerjakan. Proses kimiawi semen dan kuat tekan beton sangat tergantung dari kandungan yang terdapat dalam air campuran. Penelitian ini dilakukan untuk melihat pengaruh kandungan sulfat dalam air tanah yang digunakan untuk campuran beton terhadap kuat tekan. Metode penelitian ini adalah eksperimental, yaitu mengambil beberapa sampel air tanah yang terdapat di wilayah pesisir Kabupaten Bireuen untuk diuji kandungan kimianya. Air tanah tersebut kemudian digunakan untuk campuran beton dengan faktor air semen (FAS) 0,65. Uji kuat tekan beton dilakukan pada umur 3, 7, 14 dan 28 hari. Hasil penelitian menunjukkan bahwa ion sulfat yang terkandung dalam air campuran beton berpengaruh negatif terhadap kuat tekan beton. Sehingga, semakin besar kadar kandungan sulfat dalam air campuran maka kuat tekan beton semakin kecil. Air campuran beton yang mengandung ion sulfat juga memperlambat proses hidrasi dan perkerasan beton sesuai dengan konsentrasi kadar kandungan sulfatnya.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
