Abstract

Abstrak Indikasi kekuatan tekan beton dapat ditentukan dengan Destructive Test (DT) dan Non-Destruktive Test (NDT). Core Drill (CD) termasuk DT dapat menyebabkan perlemahan kekuatan elemen struktur namun hasilnya dapat menginformasikan mutu beton yang representatif. Hammer Test (HT) relatif mudah dilaksanakan namun hasilnya sering dipertanyakan. Penelitian ini bertujuan mendapatkan formulasi kuat tekan dalam fungsi nilai pantul palu dengan eksperimen menggunakan pelat beton ukuran 30x75x15 cm dengan komposisi berat 1PCC:2,697Ps:2,201 Kr, w/c sebesar 0,5. HT pola segiempat dan radial dilakukan setelah beton mengeras. Spesimen silinder 80x150 mm diambil dengan CD pada umur 14, 21, 28 dan 35 hari selanjutnya diuji tekan. Penelitian ini menyimpulkan untuk HT α sebesar 90o pola segiempat, kuat tekan dengan formulasi , Rn rerata nilai pantul pusat dan empat pada sudut bujur sangkar dengan sisi minimum 3,6 cm, serta dalam pola radial dengan formulasi , Rn rerata nilai pantul pada pusat pengujian dan 4 lainnya keliling merata dalam radius minimum 2,5cm dari pusat. Kata kunci: Kuat tekan beton, hammer test, core drill, destructive test, non- destructive test  Abstract Indication of concrete compressive strength can be determined by Destructive Test (DT) and Non-Destructive Test (NDT). Core Drill (CD) including DT can cause a weakening of the strength of structural elements, but the results can inform representative concrete quality. The Hammer Test (HT) is relatively easy to perform, but the results are often questionable. This study aims to obtain the formulation of compressive strength in terms of hammer reflection value, by experimenting with a concrete plate measuring 30x75x15 cm with a weight composition of 1PCC:2.697Ps:2.201Kr, w/c as 0.5. HT rectangular and radial patterns are carried out after the concrete hardens. Cylindrical specimens of 80x150 mm were taken with a CD at the age of 14, 21, 28 and 35 days and then compressed. This study concludes that for HT α as-90o quadrilateral pattern, compressive strength with the formulation   , Rn mean central and four reflected values at the corners of a square with a minimum side of 3.6cm, as well as in a pattern radial with the formulation , Rn is the average reflectance value at the center of the test and the other 4 circumferences evenly within a minimum radius of 2.5cm from the center. Keywords:   Concrete compressive strength, Hammer Test, Core drill, Destructive Test, Non-Destructive Test.
