ABSTRACT: Geopolymer concrete uses pozzolanic materials such us fly ash to replace the role of cement. This study aims to design a geopolymer concrete mixture to obtain a compressive strength value based on the age or variation of the concrete mix and identify the effect of variations in alkaline activator solution on the compressive strength of geopolymer concrete. Fly ash which reacts with alkaline activator liquid in a ratio of 50:50, funcitions as a binder, where the alkaline activator used in this study is Na2Si03, and NaOH concentration of 10M with the test variable used is variation one at a ratio of 50:50; variation two at a ratio of 60:40 and variation three at a ratio of 66,67:33,33, while the filler composition and binder were 75:25. In this research, 27 samples were made of cylindrical specimens by testing the compressive strength of concrete at the age of 7, 21 and 28 days. The mixing method used in this research was the wet mixing method. Based on the research result, the average compressive strength at seven days for each variation was 11,533 Mpa; 9,300 Mpa and 12,367 Mpa. At 21 days each variation in a row was 9,300 Mpa; 11,567 Mpa and 14,800 Mpa. Each variation’s concrete with 28 days of age successively was 10,500 Mpa; 14,400 Mpa and 12,533 Mpa.

ABSTRAK: Kota Tarakan memiliki jumlah penumpang berangkat/naik speedboat tertinggi dibandingkan kabupaten lain di Provinsi Kalimantan Utara. Hal ini seharusnya juga diimbangi dengan fasilitas pelayanan di terminal penumpang yang memadai, agar tercipta kenyamanan bagi pengguna jasa, yang kemudian akan berdampak positif dalam aspek sosial-ekonomi Kota Tarakan dan Provinsi Kalimantan Utara. Beberapa variabel yang menjadi acuan dalam penilaian tingkat kepuasan pengguna jasa terhadap kinerja terminal penumpang Pelabuhan Tengkayu I adalah reliability, responsiveness, assurance, empathy dan tangibles. Untuk mengetahui tingkat kepuasan pengguna jasa, indikator-indikator yang perlu dilakukan pembenahan, serta urutan prioritas penanganannya, maka dilakukan beberapa langkah analisis dengan pengumpulan data berupa survei dengan penyebaran kuesioner dan wawancara. Kemudian analisis data dilakukan dengan metode Customer Satisfaction Index (CSI), Importance Performance Analysis (IPA) dan Quality Function Deployment (QFD). Berdasarkan analisis CSI diperoleh kesimpulan nilai keseluruhan CSI adalah 70,13% (Puas). Berdasarkan analisis IPA diperoleh kesimpulan tiga indikator yang menjadi prioritas utama untuk dibenahi segera, yaitu kelengkapan alat-alat keselamatan di ruang tunggu, tersedianya papan pengumuman jadwal keberangkatan dan kedatangan speedboat serta tersedianya ruang perawatan untuk orang sakit. Berdasarkan analisis QFD diperoleh urutan prioritas penanganan item “what” secara teknis, pertama merencanakan dan menentukan jalur evakuasi, kedua perencanaan atau penambahan ruang perawatan, ketiga menentukan dan memasang informasi letak titik kumpul, keempat memasang informasi nomor telepon darurat di dalam ruang tunggu, kelima pengadaan dan pemasangan tabung pemadam kebakaran di dalam ruang tunggu, keenam memperbaiki sambungan kabel TV informasi yang terputus, ketujuh merekrut petugas kesehatan dan kedelapan melakukan penyesuaian ulang terhadap jadwal keberangkatan dan kedatangan Speedboat yang terbaru.

Abstract The paper presents a theoretical analysis that models the effects of temperature load induced on a two-pole, twobox reinforced concrete bridge. Implemented was theoretical analysis of thermodynamic effects, which was performed on a closed double-box reinforced concrete bridge structure. The modelling and analysis only considered the upper part of the load-bearing bridge structure. This type of bridge was selected to present the results of this study which analysed the worst effects of temperature acting on the bridge structure.

Implemented was theoretical analysis of thermodynamic effects, which was performed on a closed double-box reinforced concrete bridge structure. The modelling and analysis only considered the upper part of the load-bearing bridge structure. This type of bridge was selected to present the results of this study which analysed the worst effects of temperature acting on the bridge structure.","PeriodicalId":30755,"journal":{"name":"Selected Scientific Papers Journal of Civil Engineering","volume":"41 1","pages":"1 - 13"},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89172983","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Abstract This research is oriented towards the valorisation of local materials and the reduction of energy consumption with the aim of judicious use of these materials. In front of the world economic crisis, that also affects our region, it is necessary to solve the problem of pollution and enable important links for the balance with nature. In Algeria, buildings are very inefficient in terms of energy use and therefore remain a major source of energy consumption. To reduce this consumption and improve the thermal comfort of a building and save energy, it is necessary to use particularly high-performance materials that ensure good thermal insulation. The objective set in this work is to study the thermal behaviour of walls of different compositions, in order to identify those that allow the greatest energy savings in the case of air-conditioning for the Saharan context. The results proved that it is possible to use local materials to reduce energy consumption by 50% and save energy, improve the performance of the construction, and ensure the thermal comfort of buildings.

Abstract The estimation of deformations after a large number of cycles is a major concern of geotechnical engineers. This paper presents an explicit formulation of the accumulated cyclic volumetric strain. This study is concerned with cyclic triaxial tests simulated through the calculation by the Finite Element Method. The parameters of identification of the first cycle (loading-unloading) are determined step by step, using, as a soil behavior model, the Soft Soil Hardening Model, then, the behavior of the soil after N cycles (N ---gt--- 1000) is simulated through the formulation proposed as a pseudo-creep. The comparison of the proposed method with several cyclic triaxial tests and a shallow foundation under cyclic loading approves the good compatibility of the proposed formula for this type of problem. This study does not take into account the effect of the grain size and the void ratio, things that can be translated by the coefficients C1 and C2.

Abstract Comparative research on the influence of daylight and visual environment on melatonin oscillations and the performance of space users was realized in two identical rooms with different glazing at the Faculty of Civil Engineering of the Slovak Technical University in Bratislava. The glazing in the windows had significantly different transmittances of melanopic light. This article presents measured changes in the intensity of photopic and melanopic daylighting values inside the rooms on horizontal and differently oriented vertical plane. Photopic and melanopic illuminances were measured under cloudy and partly clear skies during several months in 2021 and 2022. The article is also partially devoted to the effect of light from a computer monitor on the spectral composition of light on the eye of a person working with a computer. The article also analyzes the problems associated with the evaluation of non-visual aspects of daylighting of the interior spaces of buildings.
