Abstract

FRP (Fiber Reinforced Polymer), such as glass fiber or GFRP (glass fiber reinforced polymer) and carbon fiber or CFRP (carbon fiber reinforced polymer), are environmentally friendly materials that can be added to structural materials. This material has a high level of flexibility and resistance, corrosion resistance, and elasticity, with low installation costs, so it has the potential as a building material, especially in earthquake-resistant areas. This study aims to determine the flexural capacity of standard reinforced concrete beams with hybrid FRP layer reinforcement (GRFP-s and CFRP-s) using various glass fiber and carbon fiber concentrations. The research was designed by designing loads and beams for the flexural capacity of reinforced concrete beams using FRP Hybrid layers (GFRP-s and CFRP-s). Six specimens of reinforced concrete beams were made with 2 specimens, namely BN (standard beams without using U-wrap and FRP) and BGC (beams using 2 layers of FRP reinforcement, namely GFRP-s and CFRP-s using U- wrap GFRP- s). Load cell readings for beam testing are carried out every 1 kN loading. Three LVDT (Linear Variable Displacement Transducers) are installed at the bottom of the beam to record the deflection in the beam. Installation of Strain Gauge (SG) to measure the beam's pressure and (deformation or strain). The test was carried out on a frame made of steel profiles designed with simple bearings (roll-joints) to test the flexural strength of the beam with a beam length of 3300 mm and a rectangular cross- section with dimensions of 150 x 200 mm. The results showed that the addition of FRP with 100% GRFP and 75% CFRP had optimum stress with a significant strain value, so it was perfect for flexural reinforcement of reinforced concrete.

Abstract

Geopolymer is an inorganic material that has brittle properties with low tensile strength. PVA fiber is one of the solutions to improve the strength of geopolymer. This research focuses on the flexural behavior of reinforced concrete beams strengthened by fly ash-based geopolymer and PVA fiber as an additive to get composited with the conventional concrete. The composite layer is applicated to repair and reinforcement of the deteriorating structure. This study was carried out with two variations of materials, named geopolymer with and without PVA fiber and normal concrete as a control beam. Also, there are two variations in the length of repaired and strengthen reinforced concrete beams, those are 1500 mm and 2700 mm in length and with 50 mm in thickness. The results show that the geopolymer mortar with fiber is more ductile compared to the control beam, in which it shows an increase into the maximum load and stiffness. On the other hand, about the failure mode, the geopolymer mortar beam without PVA fiber experienced debonding failure, while the geopolymer mortar beam with PVA fiber experienced delamination failure

Abstract

The earthquake in Central Sulawesi in September 2018, accompanied by tsunami and liquefaction, caused very significant infrastructure damage, especially in Palu City. Roads are one of the vital infrastructures that have suffered a lot of damage. Efforts to rehabilitate roads due to the disaster have been carried out and have left quite a lot of old road pavement material. This dredging material needs to be optimized for use, especially in new pavements. Because this can make new materials efficient, especially aggregates in the pavement mixture. The use of new aggregates can be conditioned to a minimum by making efficient use of recycled materials. Namely by determining the type of pavement layer that best suits the gradation conditions of the recycled material. The purpose of this study was to obtain the type of flexible pavement layer that best suits the gradation of post-disaster recycled material based on standard specifications. The method used is sieving analysis of recycled material from several locations in Palu City that were affected by the disaster. The results showed that the use of post-disaster recycled materials, based on the recycled aggregate suitability value, was the AC-WC layer of 78.33%, the HRS-WC layer of 70%, the AC-BC layer of 66.67%, the layer of AC-Base is 41.67% and SMA-Thin layer is 40%. Based on the grading analysis, post-disaster recycled material in Palu City is most suitable for the AC-WC layer type because the addition of new aggregate is the least, resulting in the most optimal use of recycled material.Kata kunci: Recycled Material, Post Disaster Material, Flexible Pavement, Gradation

Abstract

This research aims to assess the feasibility of the mechanical strength and the durability of the concrete containing 50% nickel slag and a combination of 15% and 30% fly ash with a water-cement ratio of 0.25 and 0.45 in a marine environment. Four types of concrete, namely OPC-sand (C) as control concrete, OPC-50GNS (S), 15FA-50GNS (F1), and 30FA-50GNS (F2) as comparison concrete, were tested with a 100×200 mm cylindrical specimen. The results showed an increase in the mechanical strength and potential resistance of the comparison concrete at the age of 28 days. While at the age of 180 days, fluctuating changes were found. The compressive strength of S concrete increased by 36.9 and 9.3% respectively, F1 concrete by 37.7% and 1.7%, F2 by 33.7% and 5.9% at ratio 0.45 and 0.25. Likewise, the value of the split tensile strength and modulus of elasticity of concrete. This result was followed by reduced porosity, sorptivity, and chloride penetration resistance as an indication of better concrete durability. Fly ash appears to have a greater positive impact on potential durability than mechanical strength at a water cement ratio of 0.25 versus 0.45. Although the chloride penetration resistance is decent, the compressive strength of concrete with a water-cement ratio of 0.45 does not qualify for application in the marine environment. In contrast, concrete with a water-cement ratio of 0.25 containing 50% nickel slag and the addition of class C fly ash up to 30% was declared suitable for application to concrete in the marine environment zone C2 according to ACI 318-19. Doi: 10.28991/CEJ-2022-08-12-010 Full Text: PDF

Abstract

Grouting merupakan metode perbaikan kerusakan struktur yang sering kali digunakan saat ini karena menerapkan standar corps of engineering CDR C-621 dan ASTM C-1107. Tujuan penelitian ini untuk mengetahui pengaruh penambahan sika grout pada balok beton yang telah mengalami kondisi spalling. Dalam penelitian ini digunakan Sika grout 215 yang mempunyai karakteristik tidak susut, tidak korosif, dan dapat mengalir dengan baik sehingga dapat dengan mudah mengisi bagian-bagian kecil pada beton dimana digunakan benda uji berupa balok beton bertulang dengan dimensi 150 mm x 200 mm x 3300 mm, mutu beton yang digunakan 20 MPa. Benda uji yang dibuat dalam dua variasi yaitu balok beton bertulang tanpa grouting yang berfungsi as balok kontrol diberi simbol BK sebanyak 3 buah. Variasi kedua balok beton bertulang dengan penambahan sika grout pada daerah tarik balok dan diberi simbol BGR sebanyak 3 buah balok. Hasil penelitian menunjukkan beban maksimum balok BGR menurun 47,62% dibandingkan balok BK, hal ini menunjukkan bahwa penggunaan grouting pada balok yang mengalami kerusakan tidak mampu meningkatkan kapasitas kekuatan beton tetapi hanya berfungsi sebagai perbaikan untuk menutupi beton yang mengalami spalling agar bentuknya seperti semula. Hasil uji balok BK menunjukkan bahwa semua balok mengalami kegagalan lentur sedangkan untuk balok variasi mengalami kegagalan debonding.

Abstract

The previous research of using truss system reinforcement in the beam without concrete (BTR) in the tension zone causes a decrease in flexural capacity due to the failure in the area near the support. Therefore, it is necessary to add tensile reinforcement in the support zone. This study aims to analyze the ultimate capacity of the truss system concrete beam strengthened with tensile reinforcement and to analyze the effect of tensile reinforcement in support zone due to crack pattern. This study was conducted experimentally in the laboratory. The dimension of truss reinforced concrete specimens are 15 cm x 20 cm x 330 cm that added tensile reinforcement with three types of length, they are BTRP 40D, BTRP 50D, and BTRP 60D, where D (13 mm) is diameter of tensile reinforcement. The flexural test is carried out by monotonic static loading. The results showed that tensile reinforcement in BTRP 40D was not able to carry the ultimate capacity due to premature failure in the support zone. while BTRP 50D and BTRP 60D specimens can enhance the ultimate capacity without facing premature failure in the support zone. The tensile reinforcement of 60D has the highest ultimate capacity because it can carry the biggest loads and minimum crack pattern.

Abstract

Pemanfaatan material perkerasan jalan pasca bencana di Kota Palu dan penggunaan material lokal yaitu Asbuton Butir Lawele diharapkan dapat bersinergi dengan baik pada campuran Beton Aspal Lapis Aus (AC-WC). Tujuan dari penelitian ini adalah untuk menguji pengaruh penggunaan material daur ulang (RAP) dan asbuton butir terhadap sifat volumetrik campuran AC-WC. Bahan RAP yang digunakan dalam campuran adalah 20% dari berat campuran dan variasi asbuton yang digunakan adalah 0%, 3%, 6% dan 9% dari berat campuran. Berdasarkan hasil pengujian diketahui bahwa penambahan material RAP dan asbuton butir pada campuran AC-WC dapat mempengaruhi sifat volumetrik campuran. Nilai rongga dalam campuran (VIM) dan rongga dalam agregat mineral (VMA) akan meningkat seiring dengan peningkatan persentase asbuton. Sebaliknya, rongga yang terisi aspal (VFB) akan berkurang dengan bertambahnya jumlah asbuton. Sehingga dapat dikatakan bahwa campuran AC-WC yang mengandung RAP dengan penambahan asbuton butir, akan mengalami perubahan volumetrik jika dibandingkan dengan campuran tanpa RAP dan asbuton butir. ABSTRAK Utilization of post-disaster pavement materials in Palu City and Indonesian local materials, namely Asbuton Butir Lawele, are expected to synergize well in Asphaltic Concrete Wearing Course (AC-WC) mixture. This studio aims to examine the effect of recycled materials (RAP) and granular asbuton on the volumetric properties of the AC-WC mixture. The RAP material used in the mix is 20% of the mixture weight and variations of asbuton used are 0%, 3%, 6% and 9% of the mixture weight. Based on laboratory results, it was found that the addition of RAP material and granular asbuton to the AC-WC mixture could affect the volumetric properties of the mix. The value of voids in the mixture (VIM) and voids in mineral aggregates (VMA) will increase as the proportion of asbuton increases. On the other hand, the void filled with asphalt (VFB) will decrease with the increasing number of asbuton. So it can be said that the AC-WC mixture containing RAP with the addition of granular asbuton, will experience volumetric changes compared to the mix without RAP and granular asbuton.

Abstract

The penetration index (PI) of bitumen is one of the parameters to measure the temperature sensitivity of bitumen. The bitumen quality will decrease if the bitumen's resistance to temperature changes decreases. This evaluation was based on previous research that used recycled bitumen from the extraction process. Bitumen modification was done by adding different percentages of recycled bitumen to fresh bitumen. PI values were determined using the Pfeiffer and Van Doormall equation, which shows the relationship between penetration and bitumen softening point. Based on the analysis, it was found that adding recycled bitumen up to 30% can increase the PI of bitumen, but the PI of bitumen will decrease with the addition of RAP. Adding recycled bitumen can reduce the bitumen's resistance to temperature, so a rejuvenating agent is needed to restore the physical properties of bitumen containing a high percentage of recycled bitumen. ABSTRAK Indeks penetrasi (PI) bitumen merupakan salah satu parameter untuk mengukur sensitivitas bitumen terhadap temperatur. Sensitivitas bitumen terhadap temperatur dipengaruhi oleh perubahan viskoelastis bitumen. Kualitas bitumen akan menurun bila ketahanan bitumen terhadap perubahan temperatur juga menurun. Evaluasi ini didasarkan pada penelitian sebelumnya yang menggunakan bitumen daur ulang dari proses ekstraksi. Modifikasi bitumen dilakukan dengan menambahkan bitumen daur ulang dengan presentase yang berbeda pada fresh bitumen. Nilai PI ditentukan menggunakan persamaan Pfeiffer dan Van Doormall, yang menunjukkan hubungan antara nilai penetrasi dan nilai titik lembek bitumen. Berdasarkan hasil analisis diperoleh bahwa penambahan bitumen daur ulang hingga 30% dapat meningkatkan nilai PI bitumen, namun PI bitumen akan menurun seiring penambahan RAP. Berarti bahwa penambahan bitumen daur ulang dapat menurunkan ketahanan bitumen terhadap temperatur sehingga bahan peremaja diperlukan untuk mengembalikan sifat fisik bitumen yang mengandung bitumen daur ulang dengan persentase yang tinggi.
