“…As the strength value of the produced concrete samples increased, an increase was observed in the RI values of the test hammer. Similar results were obtained in other studies [51]. A detailed examination of these graphics clearly shows that the estimated values for f c ,3 days were better than those for f c ,90 days.…”

This study aims to develop combined methods with dual and triple use of different non-destructive test (NDT) methods and to examine the effectiveness of these methods. For this purpose, nine different high-strength concrete series were produced, and destructive and NDT methods were applied to these samples on the 3rd and 90th days. Surface hardness, ultrasonic pulse velocity, and penetration resistance were considered from NDT methods. Analyses were made on the response surface method using the NDT measurements and compressive strength values obtained, and four different mathematical models were developed. Models 1, 2, and 3 were designed with dual use of NDT methods, and model 4 was designed with triple use. The absolute relative deviation values for all the developed models’ early and final-age strengths were below 10%. It is of great importance to determine concrete quality with high accuracy and practicality, especially in places like Elazig, where there are thousands of newly constructed buildings since the Sivrice-Elazig earthquake, and rapid production is required. Therefore, it is thought that determining the strength values with high accuracy using the developed combined methods without damaging the building element will provide benefits in terms of time, labor, and cost.

“…Pendekatan maturity pertama diusulkan pada awal 1950-an adalah metode faktor suhu-waktu (TTF), sering disebut sebagai fungsi kematangan Nurse-Saul. Fungsi maturitas Nurse-Saul telah distandarisasi dalam ASTM C1074 pada tahun 1987 dan populer sebagai metode maturitas di Amerika Utara karena kesederhanaannya (Miller et al, 2022). Maturity dapat dihitung dari riwayat suhu beton menggunakan persamaan:…”

Saat ini dengan menggunakan metode maturitas lebih relatif sederhana untuk menilai perkembangan kekuatan beton selama konstruksi di tempat. Penelitian untuk menentukan hubungan antara nilai kematangan dan kuat tekan pada beton berumur 1, 3, 7, 14, 21, dan 28 hari dengan variasi faktor air semen 0,4 0,45 0,5 0,55 0,6 dan variasi campuran fly ash 10%, kemudian penerapan persamaan fungsi regresi non linier untuk memprediksi kuat tekan beton berdasarkan temperature-time factor. Penelitian ini mengkaji pengaruh faktor air semen dan bahan tambahan pada campuran beton terhadap tingkat kematangan dan kekuatan beton. Benda uji yang digunakan adalah beton konvensional, berbentuk silinder dengan diameter 15 cm dan tinggi 30 cm. tujuan penulisan ini adalah untuk mengetahui implementasi persamaan fungsi regresi non linier untuk memprediksi kuat tekan beton di bawah umur 28 hari berdasarkan temperature-time factor pada beton dengan jenis dan campuran yang sama.Hasil pengukuran suhu beton pada umur awal (0 hingga 1 hari) campuran beton dengan faktor air semen yang lebih kecil menghasilkan suhu awal beton yang lebih tinggi. Sedangkan beton dengan campuran fly ash menunjukkan suhu awal yang lebih rendah dan Hasil nilai kuat tekan beton pada FAS 0,5 hingga FAS 0,6 dihasilkan nilai kuat tekan yang lebih tinggi pada campuran beton dengan faktor air semen yang lebih rendah.Berdasarkan uji regresi linear pada hubungan antara faktor air semen dan maturity, didapatkan nilai koefisien determinasi (R2) sebesar 84,9%. Dimana perubahan pada variabel X dapat dijelaskan oleh variabel Y.

“…ASTM C1074-11 includes two different functions: (a) the Nurse-Saul function [2,3] and (b) the function proposed by Freiesleben Hansen and Pedersen [4]. Other maturity functions have also been proposed, however, in-depth analysis of their reliability and limitations has been reported elsewhere [5][6][7][8][9].…”
