چکیده

Abstrak Artikel ini menyajikan tentang balok beton bertulang yang tulangannya telah korosi kemudian diberi perkuatan ekternal berupa serat glass tipe lembaran atau Glass Fiber reinforced Polymer-Sheet (GFRP-S). Pada studi variabel berdasarkan variasi tingkat pada tulangan. Lima macam benda uji digunakan berbentuk dengan dimensi 15x20 cm panjang 160 cm. Tulangan utama besi f12 dan tulangan sengkang f8-100. Mutu 25 MPa. Balok bertulangan normal tanpa sebagai kontrol (BN), GFRP-S (BP), (BPK), waktu pengkorosian selama 2 minggu (BPK ), 4 ) 6 metode perendaman larutan asam sulfat 2,0%. diperkuat daerah Tarik di bagian bawah balok. Pengujian lentur twopoint load . Hasil penelitian menunjukkan bahwa mempunyai kapasitas lebih besar dibandingkan sebesar 12,07%. (pengkorosian minggu) cenderung menurunkan namun kapasitasnya masih dari 1,38%. Kata kunci: beton, korosi, sulfat, Abstract This article presents about concrete beams whose reinforcement has been corroded and then externally in the form of sheet type fiber or Reinfroced In this study, variables are based on variations level corrosion reinforcement. Five kinds test objects used blocks with dimensions length The main is f8-100 stirrup quality Normal without as control time for weeks )and by immersion method 2.0% sulfuric acid solution. beam Tensile region at bottom beam. Flexural two point load. results showed that had a larger capacity than 12.70%. Reinforced higher rate (6 corrosion) tend to reduce but its still 1.38%. Keywords: beam, reinforcement, acid,
