| dc.description | Steel slag dihasilkan dari proses pemisahan cairan baja yang dipanaskan di
tungku-tungku cetakan pembuatan baja. Steel slag merupakan limbah padat yang
dapat digunakan sebagai alternatif bahan kontruksi bangunan. Penelitian ini
bertujuan untuk menentukans karakteristik beton segar modifikasi baru dengan
memanfaatkan steel slag sebagai subsitusi agregat kasar. Variasi subsitusi agregat
kasar steel slag yaitu 50% dan 100%, serta menggunakan Chemical Admixture yang
berupa Plastocrete RT 06 kadar 0,6%, dan Sikament NN kadar 3% dari berat semen.
Kuat tekan rencana beton sebesar 37,35 Mpa, dengan menggunakan benda uji
berbentuk silinder berukuran diameter 7,5 cm, dan tinggi 15 cm. umur pengujian
beton yaitu selama 7 hari, 21 hari, dan 28 hari. Dari hasil setting time, didapatkan
sampel beton variasi subsitusi agregat kasar steel slag 50% yaitu 120 menit, steel
slag 100% yaitu 105 menit, sedangkan variasi beton normal additive lebih lambat
ikat yaitu 130 menit. Hasil pengujian kuat tekan beton normal additive umur 28 hari
menghasilkan nilai rata-rata yaitu 23,1 Mpa, beton variasi subsitusi agregat kasar
steel slag 50% yaitu 25,135 Mpa, dan beton variasi subsitusi agregat kasar steel
slag 100% yaitu 36,745 Mpa. Pengujian kuat tekan beton modifikasi lebih kecil
dari kuat tekan rencana. | en_US |
| dc.description.abstract | Steel slag is produced from the process of separating the steel liquid heated
in a mold of making steel. Steel slag is a solid waste it can be used as an alternative
of building construction material. This study aims to analyze the characteristics of
the new modified fresh concrete by utilizing steel slag as a coarse aggregate
substitution. The variation of coarse aggregate substitution of steel slag was 50%
and 100%, and used Chemical Admixture in the form of 0.6% of Plastocrete RT 06
and 3% of Sikament NN of the weight of cement. The compressive strength of the
concrete plan was 37,35 Mpa, and used a cylindrical specimen with 7,5 cm in
diameter, and 15 cm in height .Soaked the concrete for 7 days, 21 days, and 28
days. From the time set, it was found that the concrete sample of the 50% coarse
aggregate substitution variation of steel slag was 120 minutes, 100% steel slag was
105 minutes, and the normal additive concrete variation was slower; thus requiring
a binding time of 130 minutes. The test results of normal additive concrete
compressive strength within 28 days produced an average value of 23,1 Mpa,
concrete variation of 50% and 100% steel slag substitution concrete coarse
aggregate were 25,135 Mpa, and 36,745 Mpa, respectively. The test of modified
concrete compressive strength was less than the planned compressive strength | en_US |
