Absorption Characteristics of Cement Combination Concrete Containing Portland Cement, fly ash, and Metakaolin Folagbade Samuel Olufemi
Civil Engineering Dimension Vol. 18 No. 1 (2016): MARCH 2016
Publisher : Institute of Research and Community Outreach - Petra Christian University

The resistance to water penetration of cement combination concretes containing Portland cement (PC), fly ash (FA), and metakaolin (MK) have been investigated at different water/cement (w/c) ratios, 28-day strengths, and depths of water penetration using their material costs and embodied carbon-dioxide (eCO2) contents. Results revealed that, at equal w/c ratio, eCO2 content reduced with increasing content of FA and MK. MK contributed to the 28-day strengths more than FA. Compared with PC, FA reduced cost and increased the depth of water penetration, MK increased cost and reduced the depth of water penetration, and their ternary combinations become beneficial. At equal strengths and levels of resistance to water penetration, most of the cement combination concretes are more environmentally compatible and costlier than PC concrete. Only MK binary cement concretes with 10%MK content or more and ternary cement concretes at a total replacement level of 55% with 10%MK content or more have higher resistance to water penetration than PC concrete.

The combination of concrete and steel form economical and efficient composite material by means of the created cooperation through bond stress on the interface of both materials. Heating at varying temperature would result in behaviour change of the composite material, particularly regarding its bond stress performance due to the microstructure change of the concrete and steel. The uniaxial compression test indicated that the value of concrete compression strength on seven days if heated at 2000 C , 5000 C, and 8000 C temperature would decrease, varying from six to 100%, whereas the decrease of concrete compression strength on 28 days varying from ten to 90%. At 2000 C heating, the decrease of bond stress between steel and concrete on 28 days was approximately 30%. Heating at a higher temperature or at 5000 C would lead to 40% to 77% decrease. The decrease of concrete compression and that of bond stress due to heating was presented by a non-linear curve showing that there was a positive correlation between the two characteristics. Abstract in Bahasa Indonesia : Perpaduan antara material beton dan baja tulangan akan membentuk material komposit yang ekonomis serta efisien lewat hasil kerjasama yang tercipta melalui kekuatan lekat pada interface kedua material tersebut. Pemanasan dengan temperatur yang bervariasi akan menyebabkan terjadinya perubahan perilaku material komposit tersebut, khususnya menyangkut kinerja kekuatan lekatnya akibat perubahan mikrostruktur pada material beton dan material baja tulangan. Dari hasil uji tekan uniaksial diperoleh nilai kuat tekan beton umur tujuh hari yang bila dipanaskan dengan temperatur 200oC, 500oC dan 800oC akan mengalami penurunan yang bervariasi antara enam hingga 100%, sedangkan penurunan kuat tekan beton pada umur 28 hari berkisar antara sepuluh hingga 90%. Pada tingkat pemanasan dengan temperatur 200oC, penurunan kekuatan lekat antara baja tulangan dan beton umur 28 hari adalah sekitar 30%, serta untuk pemanasan dengan temperatur yang lebih besar atau sama dengan 500oC akan terjadi penurunan sebesar 40% hingga 77%. Penurunan kuat tekan beton dan penurunan kekuatan lekat beton dengan baja tulangan akibat pemanasan dipresentasikan oleh kurva tidak linier serta menunjukkan adanya korelasi positif antara kedua karakteristik tersebu

APPLICATION OF PACKING THEORY ON GRADING DESIGN FOR POROUS ASPHALT MIXTURES Hardiman Hardiman
Civil Engineering Dimension Vol. 6 No. 2 (2004): SEPTEMBER 2004
Publisher : Institute of Research and Community Outreach - Petra Christian University

The design life of porous asphalt is shorter than dense mix as a consequence of permeability loss due to clogging and poor resistance to disintegration. To mitigate problems associated with clogging, double layer porous asphalt has been constructed in the Netherlands. This paper investigated a development of a new grading design for porous asphalt by varying percentage of aggregate with maximum sizes of 20, 14 and 10mm; a theory of packing was used. The most common method used for grading design is based on empirical, which does not relate the packing behaviour of the aggregate mass. The packing theory used in this study was facilitated by a vibratory compactor. It was found that mixtures containing aggregate sizes 14 and 10mm have a good permeability and stability, when vibrated for 65 second with a frequency of 40Hz, while for aggregates containing 20mm, to achieve the requirement for Marshall stability, the gradation needs to be modified. Properties of porous asphalt based on packing theory are better from the empirical grading from Spain (P-12).

Metaheuristic-Based Machine Learning System for Prediction of Compressive Strength based on Concrete Mixture Properties and Early-Age Strength Test Results Doddy Prayogo
Civil Engineering Dimension Vol. 20 No. 1 (2018): MARCH 2018
Publisher : Institute of Research and Community Outreach - Petra Christian University

Estimating the accurate concrete strength has become a critical issue in civil engineering. The 28-day concrete cylinder test results depict the concrete's characteristic strength which was prepared and cast as part of the concrete work on the project. Waiting 28 days is important to guarantee the quality control of the procedure, even though it is a slow process. This research develops an advanced machine learning method to forecast the concrete compressive strength using the concrete mix proportion and early-age strength test results. Thirty-eight historical cases in total were used to create the intelligence prediction method. The results obtained indicate the effectiveness of the advanced hybrid machine learning strategy in forecasting the strength of the concrete with a comparatively high degree of accuracy calculated using 4 error indicators. As a result, the suggested study can provide a great advantage for construction project managers in decision-making procedures that depend on early strength results of the tests.

Learning from Local Wisdom: Friction Damper in Traditional Building Lumantarna, B.; Pudjisuryadi, P.

Indonesia is situated in the so called “Ring of Fire” where earthquake are very frequent. Despite of all the engineering effort, due to the March 28, 2005 strong earthquake (8.7 on Richter scale) a lot of modern buildings in Nias collapsed, while the traditional Northern Nias house (omohada) survived without any damage. Undoubtedly many other traditional buildings in other area in Indonesia have survived similar earthquake. Something in common of the traditional building are the columns which usually are not fixed on the ground, but rest on top of flat stones. In this paper some traditional building are subjected to non linear time history analysis to artificial earthquake equivalent to 500 years return period earthquake. This study shows that apparently the columns which rest on top of flat stone acts as friction damper or base isolation. The presence of sliding at the friction type support significantly reduces the internal forces in the structure.

HUMAN RESISTANCE TO THE USE OF INFORMATION TECHNOLOGY IN CONSTRUCTION COMPANIES Andi Andi; Fani Fani; Heru Purwoadi
Civil Engineering Dimension Vol. 7 No. 2 (2005): SEPTEMBER 2005
Publisher : Institute of Research and Community Outreach - Petra Christian University

The process of implementing information technology (IT) often fails to bring the intended result because the human dimension is not given adequate consideration. Yet despite some evidence of failure, little has been written on the nature of human performance, compared to abundant resources about technical and procedural aspects, as it applies to the ideals of the IT philosophy. To combat peopleâs deficiencies, this paper focuses mainly on the question why people resist IT. It explores sources of human resistance to the use of IT. A survey is the conducted to personnel working for construction companies to examine the resistance sources. The result reveals personal money, habit, and threat to information security as most dominant sources for such resistance, instead of fear of employment instability as many previous researches have discussed. The paper discusses the resistances and suggests possible solutions to deal with them.

The Stability Analysis of the Lusi Mud Volcano Embankment Dams using FEM with a Special Reference to the Dam Point P10.D Agustawijaya, D.S.; Sukandi .

Publisher : Institute of Research and Community Outreach - Petra Christian University

Since the eruption of the Lusi Mud volcano in Sidoarjo, East Java, on May 2006, soil embankment dams have been built to keep hot mud within the ponds. Unfortunately, since the dams were sitting on poor weak ground, land subsidence intensively occurred around the dams. A finite element method (FEM) was, then, applied to evaluate the stability of the dams particularly of the dam point P10.D, being considered as the most unstable point over 29 other dam points. Results show that the dam displacements in vertical and horizontal directions were high. The total displacements of the final design were about 1.5 m in both static- and dynamic-state conditions. These modelled data show a similar trend with field measurement data. The dam had only a factor of safety of about 1.1, and the dam might fail through a deep slide mode.

THE PERFORMANCE OF TRADITIONAL CONTRACT PROCUREMENT ON HOUSING PROJECTS IN NIGERIA Stephen O. Ojo; Olabosipo I Fagbenle; Aderemi Y Adeyemi
Civil Engineering Dimension Vol. 8 No. 2 (2006): SEPTEMBER 2006
Publisher : Institute of Research and Community Outreach - Petra Christian University

The traditional contract procurement has been widely criticized as an ineffective procurement method because it often involves time and cost overrun on construction projects. Yet the method is still being widely used in Nigeria most especially for the procurement of housing projects. It is suspected that this procurement method may not be ineffective in all cost categories of housing projects. Therefore time and cost performances of the procurement method on 57 housing projects of varying cost categories initiated by the Nigerian government between 1993 and 1999 were studied. The category of one to five million naira (US$1.00 â 92 Nigerian Naira in 1999) showed the least time overrun of 18.98% while the highest time overrun of 99.64 % was shown in the five to ten million naira. The over ten million naira category had the least cost overrun of 9.13% while the highest cost overrun of 34.55 % was shown in the less than one million naira. The one to five million naira cost category exhibited weak correlation between time and cost overruns but the five million naira and above categories showed strong correlation. It was concluded that one to five million naira cost category is quite suitable for traditional contract procurement on housing projects in Nigeria.

Successfully executing construction project within schedule is one of the most important aims, both for the owner and the contractor. Construction delay is a condition which is completely unwanted, because it will cause lost of money and time for both parties. Research in finding factors which are dominant or having great influences as the causes of delay, is intended to prepare and build the construction planning and scheduling more complete and accurate; so that delay can be avoided or controlled. Confirmation to the founded causes by site surveys using questionaire distributed to contractors, have shown that problems arisen from inaccurate workplan, lack of resources. lack of communication/coordination, were dominant factors for causing construction delay from contractor side. On the other hand, the owner side, problems arisen from incomplete and unclear design and scope of works, inspection and control system of the project were dominant for causing delay. Abstract in Bahasa Indonesia : Keberhasilan melaksanakan proyek konstruksi tepat pada waktunya adalah salah satu tujuan terpenting, baik bagi pemilik maupun kontraktor. Keterlambatan adalah sebuah kondisi yang sangat tidak dikehendaki, karena akan sangat merugikan kedua belah pihak dari segi waktu dan biaya. Penelitian ini bertujuan menemukan faktor-faktor yang sangat berperan atau mendominasi sebagai penyebab keterlambatan, dengan maksud agar proses perencanaan dan penjadwalan proyek konstruksi dapat dilakukan dengan lebih lengkap dan cermat; sehingga keterlambatan sedapat mungkin dihindarkan atau dikendalikan. Temuan penyebab-penyebab keterlambatan, yang dikonfirmasikan dengan sigi lapangan menggunakan kuesioner yang didistribusikan kepada kontraktor, menunjukkan bahwa masalah-masalah tidak seksamanya rencana kerja, tidak tersedianya sumber daya dan kurangnya komunikasi/koordinasi, merupakan faktor-faktor yang dominan sebagai penyebab keterlamabatan dari sisi kontraktor. Dari sisi pemilik proyek, masalah ketidaklengkapan dan ketidakjelasan desain dan lingkup pekerjaan, masalah sistim pengawasan dan pengendalian proyek, merupakan faktor yang dominan sebagai penyebab keterlambatan. Kata kunci : keterlambatan pelaksanaan, penyebab keterlambatan, perencanaan dan penjadwalan, kontraktor, pemilik
