Perkuatan tiang pancang beton bawah air dengan GFRP dan epoxy underwater adalah salah satu solusi kerusakan pada bangunan demaga, dengan cara meningkatkan/ mengembalikan kekuatan tiang pancang dan menambah masa layan dari struktur dermaga tersebut. Benda uji yang digunakan pada penelitian ini terdiri dari 40 sampel silinder beton (d=150 mm dan h=300 mm). Dua puluh sampel silinder untuk uji kuat tekan dan modulus elastisitas beton serta 20 sampel silinder untuk uji kuat tarik belah beton. Perlakuan pada sampel yaitu perkuatan dengan GFRP 1 layer, 2 layers dan 3 layers. Persentase peningkatan kuat tekan pada perkuatan dengan GFRP 1 layer, 2 layers dan 3 layers berturut-turut yaitu 41,7%, 77,85% dan 192,6% terhadap beton tanpa GFRP. Persentase peningkatan kuat tarik belah pada perkuatan dengan GFRP 1 layer, 2 layers dan 3 layers berturut-turut yaitu 171,84%, 154,54% dan 240,06% terhadap beton tanpa GFRP. Maka disimpulkan perkuatan beton dengan GFRP dan epoxy underwater terjadi peningkatkan kuat tekan dan kuat tarik belah yang signifikan. Nilai modulus elastisitas (Ec) rata-rata dial gauge/modulus tanpa GFRP dan dengan perkuatan GFRP 1 layer, 2 layers dan 3 layers, berturut-turut yaitu 32753,71 MPa, 12438,51 MPa, 52946,20 MPa dan 50151,52 MPa. Maka disimpulkan hasil pengujian modulus elastisitas tidak sesuai harapan yaitu seharusnya perkuatan dengan GFRP meningkatkan modulus elastisitas beton. (The damage of concrete structures such as the porous of dock piling, often occur on underwater constructions such as buildings on the beach. The strengthening of underwater concrete piles with GFRP and epoxy underwater is one solution for dock damage, by improving/restoring load capacity of poles and increasing the service life of pier structures. The specimens used in this study consisted of 40 cylinders (d = 150 mm and h = 300 mm). Twenty cylindrical samples used for compressive strength and modulus of elasticity test as well as 20 samples used for splitting tensile strength test. The variations of GFRP strengthening in this research were 1 layer, 2 layers and 3 layers. Persentage of increment of compressive strength test of GFRP strengthening for 1 layer, 2 layers and 3 layers compare to concrete without GFRP were 41.7%, 77.85% and 192.6% respectively. Persentage of increment of splitting tensile strength test of GFRP strengthening for 1 layer, 2 layers and 3 layers compare to concrete without GFRP were 171.84%, 154.54% and 240.06% respectively. The conclusion is the cylinders strengthened by GFRP and epoxy underwater can increase compressive strength and splitting tensile strength significantly. The average modulus of elasticity (Ec) dial gauge/modulus without GFRP and GFRP strengthening for 1 layer, 2 layers and 3 layers were 32753.71 MPa, 12438.51 MPa, 52946.20 MPa and 50151.52 MPa respectively. It shows that the test result do not appropriate with the hypothesis which the cylinders strengthened by GFRP should have higher modulus of elasticity than plain cylinders.) date: 2013-12-23 date_type: published publisher: Fakultas Teknik place_of_pub: Universitas Lampung citation: Khustubin, Leni Puspa Meliani (2013) STUDI PERBANDINGAN SIFAT MEKANIS BETON DENGAN DAN TANPA PERKUATAN GFRP DAN TYFO SW EPOXY (UNDERWATER) (THE STUDY OF COMPARISON MECHANICAL CHARACTERISTIC OF CONCRETE WITH AND WITHOUT STRENGHTENING OF GFRP AND TYFO SW EPOXY (UNDERWATER)).
