Abstract

In order to promote sustainable development in the remote islands this present research attempted to study the suitability of seawater, that available abundantly surrounding the remote islands with Portland composite cement (PCC) and crushed river stones to produce concrete. This research aims to utilize seawater, and Portland composite cement (PCC) to produce high-performance concrete in order to eliminate the main problems of clean water shortage in the low land areas and the remote islands. Infrastructure development can be sustained through the effective use of natural available local materials on the remote islands. The method used in this research is an experimental method in the laboratory. Two variations of concrete were made using freshwater and seawater, respectively as a mixing material with a water to cement ratio (w/c) of 0.55. The evaluation result on concrete compressive strength and bond strength of seawater concrete were discussed. Experimental results showed the compressive strength of the seawater concrete is lower by 6.26% as compared to the normal concrete at water-cement ratio (w/c) of 0.55. In addition, the bonding strength of steel bar embedded in seawater concrete is lower by 4.34% as compared to the bonding strength of steel bar embedded in normal concrete at water-cement ratio (w/c) of 0.55. Doi: 10.28991/cej-2020-SP(EMCE)-06 Full Text: PDF

Abstract

Balok sebagai salah satu komponen struktur yang sering menggunakan beton bertulang sebagai material penyusunnya, terkadang dalam membuat desainnya masih sering kali terjadi kesalahan, sehingga hal ini dapat menyebabkan kerusakan pada balok. Kerusakan yang terjadi pada beton bertulang biasanya ditandai dengan munculnya retakan, apabila tidak segera diatasi maka dapat berlanjut pada keruntuhan struktur. Belakangan ini telah ditemukan teknologi Fiber Reinforced Polymer (FRP) yang dapat digunakan sebagai alternatif perbaikan dan perkuatan struktur. Namun demikian salah satu mode kegagalan pada beton bertulang dengan perkuatan FRP yaitu delaminas).Delaminasi pada area lekatan FRP dapat menyebabkan penurunan kapasitas komponen yang signifikan yang menyebabkan kegagalan dini dari balok beton bertulang. Oleh karena itu penelitian ini bertujuan untuk menganalisis peningkatan kapasitas pada balok yang diperkuat GFRP dan menganalisis perilaku delaminasi pada balok GFRP. Penilitian ini dilakukan di Laboratorium Struktur dan Bahan Universitas Hasanuddin. Benda uji terdiri dari 12 buah balok bertulang dengan dimensi 15 cm x 20 cm x 330 cm yang telah diperkuat dengan GFRP pada daerah lentur. Data yang diamati adalah beban maksimum, lendutan dan mode keruntuhan balok.Hasil penelitian menunjukkan bahwa balok dengan perkuatan GFRP mampu meningkatkan kapasitas lentur dari balok sebesar 4.14 % terhadap balok normal. Mode keruntuhan yang terjadi pada benda uji disebabkan karena kegagalan lekatan antara beton dengan GFRP (delaminasi). Benda uji menunjukkan perilaku yang sama saat delaminasi mulai terjadi yaitu hubungan beban regangan antara baja dan FRP sudah tidak beriringan dan ditandai dengan terdengarnya bunyi kecil, bunyi sedang, bunyi besar yang menandakan bahwa GFRP mulai terlepas dari permukaan beton.

Abstract

In general bending loads acting on structural elements of concrete beams arrested by the bottom cross secttion on the compression area while the tension area is ignored. Therefore, it is reasonable if the concrete beam section on the tension area is minimized with concrete mass reduction in tensile region by ignoring concrete tensile stress while receiving static loads or the area is filled with styrofoam concrete (styrocon). One effort to effeciency concrete economic value by reducing the concrete and use of styrocon thus component volume of natural materials, such as sand mining, coarse aggregate, and cement and weight of construction becomes smaller. Styrofoam as waste can be used as filler to reduce the volume of concrete, especially for areas where the concrete section is not working mechanically. In an effort to study the flexural strength of external reinforced concrete beams and styrofoam-filled composite, then performed a series of tests. Test material in the form of beams with dimensions of 15 cm x 20 cm x 270 cm. Test material consisted of normal beam quality 26.0 MPa concrete with transverse reinforcement as a control beam and test materials with external transverse reinforced and truss systems and styrofoam-filled composite. In the normal-styrocon composite beams with various content of styrofoam. Beam placed on 2 simple supports with 2 point loading test method. Results showed flexural capacity of the normal concrete beam is 36.7 kN, but the external reinforced beams decreased 30.6 kN, but external reinforced truss system beams is relatively equal 35.8 kN. But external reinforced beams prone to corrosion and fire and require maintenance. Therefore used styrocon on the outer portion with styrofoam content of 30%, 40%, and 50% who had a flexural strength of each 33.8 kN, 31.0 kN and 29.0 kN. It can be concluded that the use of composite concrete beams normal-styrocon can efficiency use natural materials to reduce the weight of the concrete beam and construction as well as having environmental aspects by using the waste.

Abstract

In general bending loads acting on structural elements of concrete beams are retained by the compression area on its pressured area while its drag area is being ignored. Therefore, it is reasonable if the concrete beam section on drag area is minimized with concrete mass reduction in tensile region by ignoring concrete tensile stress while receiving static loads or the area is filled with styrofoam concrete (styrocon). One effort to make efficient the concrete economic value is by reducing concrete and using styrocon thus natural material component such as sand mining, coarse aggregate, and cement and heavy construction becomes lighter. Styrofoam as waste can be used as filler to reduce the volume of concrete, especially for areas where the concrete section is not working mechanically. In an effort to study the flexural strength of concrete beams external reinforcement and composite Styrofoam filled, then a series of tests performed. Test material is in the form of blocks of 15 cm x 20 cm x 270 cm in dimension. Test material is consisted of concrete quality normal beam of  26.0 MPa with transverse reinforcement as a control of test material and the test material with external transverse reinforcement, as well as truss systems and Styrofoam filled composite. The normal-styrocon composite is beam with Styrofoam variation content. The beam is placed on 2 simple pedestal by 2 point loading method testing. The results indicated that normal concrete beam flexural strength is 36.7 kN, but the external transverse reinforcement beams decreased to 30.6 kN, but the external reinforcement beam truss system reinforcement is relatively equal to 35.8 kN. However, the beams with external reinforcement is susceptible to corrosion, fire resistant, and requires treatment. Therefore styrocon is used on the outer portion with styrofoam content of 30%, 40%, and 50% relatively having flexural strengths of 33.8 kN, 31.0 kN and 29.0 kN, respectively. It can be concluded that the use of normal-styrocon composite concrete beams can make efficient the use of natural materials of the concrete block and to reduce the weight construction as well as has environmental aspects by using the waste.

Abstract

Dalam paper ini, diperkenalkan sebuah teknik baru untuk memperkuat beton bertulang terhadap gempa. Teknik dengan metode retrofit membutuhkan pembungkus tipis-kekuatan tinggi wire mesh di bawah balok untuk meningkatkan kekuatan lentur. Oleh karena itu, penting untuk menentukan kapasitas lekatan antara wire mesh dan beton. Studi eksperimental disajikan untuk mengukur kapasitas lekatan antara wire mesh dan blok beton sebagai matriks dengan menggunakan pengujian tarik dan penentuan kekuatan lentur dari RC balok eksternal diperkuat dengan baja-kekuatan tinggi wire mesh dengan pengujian empat titik lentur. Sebuah studi parametrik dilakukan untuk meneliti efek dari parameter varian desain seperti diameter baja tulangan, beton normal (NVC), beton pemadatan-sendiri (SCC), kuat tekan, ketebalan dan jarak dari grid, dan jenis grid. Hasil penelitian menunjukkan bahwa kapasitas lekatan meningkat antara wire mesh dan SCC, dan juga kekuatan lentur dari balok beton bertulang dapat ditingkatkan secara signifikan dengan membungkus wire mesh di bagian bawah balok beton bertulang.

Abstract

Salah satu penyebab keterbatasan pengambilan sampel beton inti karena keberadaan tulangan pada struktur beton. Jika digunakan diameter core besar, dapat menurunkan kapasitas struktur beton dengan adanya tulangan yang terpotong. Oleh karena itu, dilakukan studi penggunaan core beton diameter kecil untuk memprediksi kuat tekan beton diameter kecil terhadap silinder beton diameter standar. Benda uji berupa (a) silinder beton berdiameter 10 cm dan tinggi 20 cm; (b) 2 plat beton berdimensi 45cm x 45cm x 13cm; dan (c) 4 balok beton berdimensi 70cm x 30cm x 15cm. Metode pengambilan sampel core diameter 2 inchi dan 1 inchi dengan arah sejajar dan tegak lurus arah pengecoran. Ada 2 variasi mutu beton yaitu 20 MPa dan 30 Mpa dengan MSA masing-masing 10 mm dan 20 mm. Pengujian kuat tekan dan modulus elastisitas beton dilakukan, serta uji normalitas beton inti untuk mengevaluasi kecukupan benda uji. Dari hasil pengujian dapat disimpulkan bahwa kuat tekan beton inti 2 inchi dengan pengambilan benda uji sejajar dan tegak lurus arah pengecoran memenuhi syarat uji normalitas, sehingga dapat direkomendasikan dengan jumlah sampel 25 buah, sedangkan untuk sampel berdiameter 1 inchi jumlah sampelnya perlu ditambah

DUCTILITY OF DOUBLE NOTCH CONNECTION IN PRECAST BEAM COLUMN JOINT, DUE TO CYCLIC LATERAL LOADSABSTRACTBy considering the structure of precast concrete as a monolithic structure, flexural and shear reinforcement of beam column joint can be planned based on the design capacity This research is an experimental study in a full-scale laboratory, which aims to analyze the precast ductility value of double notch models due to cyclic lateral loads. The specimen consists of two models, which are precast beam-column connections and monolithic beam column. The precast and monolithic specimen were designed for the same strength. The cross-sectional dimensions of the beam 250 mm x 300 mm and column 300 mm x 300 mm. This research was carried out with the following stages : (1). Physical Test of Concrete Materials (2). Physical Test of Reinforced Steel Material (3). Strength bonding test (4). Physical test of precast column beam connection. Tests are carried out after the concrete is more than 28 days old. The results showed that after being given a cyclic load on the two structural models, connection precast beam-column joint type of double notch (STRS) type were better able to deform under tensile loads (ductility = 5.52), while the monolith column beam components were better able to deform compressive load (ductility = 7.66). Based on the ductility value obtained, the connection of this double notch model can function as a full ductile connection, so that it can be applied to the building of earthquake force retaining structures for special moment bearers

Abstract

Piping modifications Polyvinyl Chloride as forming a hollow cavity in the concrete slab is one alternative to reduce the self-weight of structure. The placement of PVC pipe that has been modified on the concrete tensile area is expected not to reduce the bending strength of the plate. In the study, the analysis was compared to reinforced concrete slab massive (PB-1) with a hollow reinforced concrete slab PVC (PB-2) with the same thickness and compared well with hollow reinforced concrete slab PVC (PB-3) with an equal volume of the concrete slab massive reinforced (PB-1). All test objects have the same dimensions, including the number and spacing of reinforcement. The analysis method of the moment coefficient obtained flexural strength of PB-1 amounted to 328.175 kN, plate PB-2 amounted to 329.624 kN, and the plate of PB-3 amounted to 387.184 kN. While the results of the analysis using the Navier method deflections values obtained for the plate PB-1, PB-2, and PB-3 are 0.0948 mm, 0.33952 mm, and 0.04267 mm, respectively. Shear forces values for plate PB-1, PB-2 and PB-3 is 965.908 kN, 231.818 kN and 281.429 kN respectively.
