Abstract

This paper presents the results of investigation to assess the mechanical properties of geopolymer concrete made with fly ash as a base material. Previous study showed that the compressive strength of geopolymer concrete were dependent on pozzolanic materials used and the concentration of activator solution in the mixture. The effort to use Sidoarjo Mud and trass as an additive material in the mixture was investigated in this study to analyze the mechanical properties of the concrete. NaOH solution mixed with Na2SiO3 was used as the activator solution which varied from 8 M to 14 M. Ratio of Na2SiO3 to NaOH solution by mass were also varied from 0.5 to 2.5 Trass and Sidoarjo Mud were introduced as the filler and mixed with fly ash to replace the volume of fly ash. Compressive strength test of cylindrical specimens at 28 days, split strength test and porosity test were carried out comprehensively to compare the specimens from each composition. The results showed that the best concrete will be produced when denser NaOH solution was used. Ratio of Na2SiO3 to NaOH in the solution also plays an important role to improve the mechanical properties of concrete. The result of this study also shows that Sidoarjo Mud is a prospective material for making geopolymer concrete.

Abstract

Quality control problems of great importance in supporting the successful development of the project, due to carry out quality control results will be obtained in accordance with the terms specified techniques. Form of the test object in the implementation of quality control may affect the accuracy of the results, especially on standardized test specimens are not generated from the test piece drill cores. There are several sizes of test objects used in accordance with regulations such as PBI 1971dan British Standard (BS) using the test specimen size 15x15x15 cm 3, 20x20x20 cm3. ACI 318, ASTM C42/C42M 2003, using a cylindrical test specimen dimensions 15x30 cm. There is a discourse of the specimen size 10x20 cm due to the size of the specimen is sufficient in number when using a laboratory mixer other than that estimated difference with the test results are not significant 15x30. Test specimen 15x15x15 and 20x20x20 cm cube estimated results are less rigorous than the cylinder, because the cube distribution voltage is not equal than the cylinders which form a circle so that distribution is the same if the specimen is pressed. Taking the test object with a core drill is sometimes produced beyond the standard test specimen is less than 15 cm, 10 cm even for the special conditions of the drill core of 5 cm. Reasons mentioned above the authors conducted research on "Influence of aggregate diameter on compressive strength and the influence of variation of L / D of the compressive strength and the results will be compared with ASTM C42 / C42M-2003. In this study made two kinds of mixed concrete fc' = 225 kg/cm2 and fc' = 400 kg/cm2, because concrete is the most widely used in practical and concrete categories included normal quality concrete. Stage is the initial stage of examining the influence of the maximum aggregate diameter on compressive strength, to find the optimum diameter for compressive strength.

Abstract

“Fiber reinforced concrete” is made from cement, fine aggregate, coarse aggregate, water and many fibers that randomly spread within the mixture. To increase the ability of concrete to resist tensile and flexure, efforts are done by giving reinforcements or other material such as fibers in the tensile region.In this research the examination done in experiment with add plastic fibers of plastic benneser (poly-acrylonitryl styrene) in concrete mixture, with the percentage between 0% - 1, 00%.Otherwise in this research, the use of high concrete quality, are developing from the past research would have done in Unitomo. And the purpose of this research is to know the behavior of the mechanic phenomena like stretch and ductility from fibers concrete of beneser of higher concrete quality as united. So with this could be compare with the higher concrete quality without fibers. The concrete sample of fibers composite is made with three different things like: cylinders sample with size Ø10 and 15 cm high 20 and 30 cm, and block sample with size 15 X 20 X 60 cm. Cross section of full fibers composite and partial is used by block sample, only in stretch area below the neutral lines. The result says that: strengthened in splitting in a cylinder sample between 12, 56 – 27, 07 %, and the power of ductility from the block sample of full fibers between 12, 95 % – 20, 19 %, and the partial is 12 – 16, 57 %.

Abstract

Refer to Journal “ Numerical Analyses of Load Tests on Bored Piles, 2004” From the research results we can obtained that the conclusion from the Mohr Coulomb material model is more rigid than hardening material model , and the Soft Soil material model is more rigid than Mohr Coulomb material model. It is because there are difference from the formula that used in each methods.This final task goal is to compare some of configuration form of the pile group, in which consist of 2, 3, 4, 6, and 8 piles at one configuration with the distance between 2Ø and 4Ø to keep the axial or lateral load using software Plaxis 2D with material model: Mohr Coulomb, Hardening and Soft Soil. Based on calculation results using Plaxis 2D obtained result that the distance’s changes between piles will cause the addition from the ability of piles to keep axial and lateral load for same load. Then the distance’s changes between piles can reduce the decrease and deflection from piles. This study of the three material models, namely MohrCoulomb. Hardening, Soft Soil has the results of the analysis with the difference ranging from 0-1%.

Abstract

This study investigates on household factors which influence motorcycle ownership in Denpasar city, Bali by using a multinomial logit model. The analyses show that the number of family members were about 0.83 and 2.6 times more likely to own, respectively, two and three motorcycles or more than one motorcycle. Total household income of less than one million rupiahs and between one and two million rupiahs were respectively 83.7 and 84.7 percents less likely to influence three motorcycles or more than one motorcycle ownership. Meanwhile, due to its high maneuverability on the congested road, a household was about 3.3 times more likely to own three motorcycles or more than one motorcycle. The probability analyses present that a double change in number of family member could influence one, two, and three motorcycles ownership or more by 19, 34, and 48 percents, respectively.

Abstract

Nonlinear finite element analysis was applied to various reinforced concrete beams using a set of constitutive models established in the modified fixed-angle softened-truss model (MFA-STM). The model was implemented by modifying the general-purpose program FEAPpv. The model can take account of the six important characteristics of cracked reinforced concrete: (1) the softening effect of concrete in tension-compression; (2) the tension-stiffening effect of concrete in tension; (3) the average stress-strain curve of steel bars embedded in concrete; (4) the shear modulus of concrete; (5) the aggregate interlock; and (6) dowel action. The comparison shows the aggregate interlock and dowel action can reduce the overestimation of the shear capacity of high strength reinforced beam, especially the high strength reinforced deep beam without web reinforcement. Moreover, the model is suitable for being implemented numerical procedures due its simplicity.

Abstract

Utilization of waste aggregates for construction industry had been encouraged in line with increasing pressures to reduce exploration of natural aggregates. One alternative material that can be used as masonry block unit is the construction demolition waste (CDW) with asphalt as the binder (CDW block). The objective of this paper is to produce CDW block with a performance equal to the concrete block commonly used in the United Kingdom with a compressive strength between 3.5 MPa and 7 MPa and the specific creep strain less than 100 microstrain. The CDW block requires suitable particle size proportion, in order to obtain satisfactory results and to meet the demand of using minimum bitumen content and low compaction level. The CDW block requires sufficient heat curing to harden the asphalt. It was found that CDW materials were a very suitable material to be used for making CDW blocks. Compaction level of 2 MPa and curing regime of 200°C for 24 hours were sufficient and gave satisfactory results.

Abstract

Scour is a natural phenomenon caused by erosion due to water flow on the alluvial channel bed and channel wall. In fact, scour happened in the bridge abutment is total scour, that is a combination between local scour, general scour, and constriction scour. This research aims to find the depth of scour near abutment in clear-water scour condition. This research was carried out using recirculation flume. The channel model was a compound channel and using steady-uniform flow. The abutment model was Spill-Through type (ST). The depth of scour near abutment was measured in each 6 hours running at 9 point of position. The research result shows that the maximum scour depth happened at point of separation. The depth of scour is mostly affected by Reynold and Froude number of flow. In general, the scour pattern happened around abutment is the same at every running which can be seen in the scour contour pattern that has half horseshoe shape.

Abstract

Performance-based design is becoming increasingly popular in designing a seismic resistant building. In the study, a twelvestory, reinforced concrete office building with asymmetric configuration using dual system located in seismic zone 6 was designed conforming to the Indone sian S e i smi c Code SNI 03-1726-2002 and the Indonesian Concrete Building Code SNI 03-2847-2002. The seismic performance of the building was evaluated using the Static Nonlinear (Pushover) Analysis and Inelastic Dynamic Time History Analysis. The performance point obtained from the pushover analysis was defined using various methods, such as FEMA 356, ATC-40, FEMA 440, and SNI 03-1726-2002. The result of the study indicated that the highest performance point was that obtained according to FEMA 356 and FEMA 440, whereas the lowest value was that in accordance with SNI-03-1726-2002. The roof displacement difference of that obtained from El-Centro dynamic analysis and performance-point pushover analysis can reach up to 5 cm and 2.4 cm in X- and Y-directions, respectively. This indicates that the pushover analysis is quite accurate for evaluating the corresponding building since the first mode shape is quite dominant.

Abstract

Unsignalized intersections, which are locations, with high potential traffic congestion, are the largest number of intersections in large cities in developing country such as Indonesia. Moreover, a number of side frictions worsen traffic congestion and then decrease performance of intersection. Some Regulator traffic signs have been installed to reduce traffic congestion at these locations. However, road users especially angkot (local public transportation mode) drivers ignored the signs. The purpose of this paper is to analyze the effects of side friction reduction to the performance of the intersection. Unsignalized intersection at Rajawali-Dadali in Bandung, Indonesia was used as a case study. Results of this paper showed that at the intersection with capacity of around 4000 pcu/hour, degree of saturation of 0.91 and delay of 15.3 second/pcu, traffic signs alone were not effective. The presence of police officer increased 8.46 percent of capacity, decreased 2.72 percent of degree of saturation, and decreased 4.93 percent of delay at the intersection. However, since the presence of police officers are not always available even during peak hours, it is recommended that the unsignalized intersections with high degree of congestions be changed into signalized intersections.
