Abstract

AbstractThe building structure were built by beam elements and column elements. In addition to the factors of strength and rigidity ensure the safety of the structure, the basic principles that should be getting attention in the calculation of the structure is the economic factor is realized through cross-sectional dimensions of the structural elements. Capacity utilization of the full cross-section, will becomes the basic point section design process more realistic because the load can be set appropriately and furthermore, the safety factor can be set as well. The case studies of minimum weight of the structure in the form of the structure has a geometrical regular-shaped portal is simple with a static load centralized, dimensions of the structural elements of the profile shape-I restricted to only two (2) types of each of the columns and beams, cross sectional plastic caused only by bending and normal (influence other body force the ignored / not reviewed), the weight of the structure is the total weight of all the structural elements in the form of beam elements and column elements, the objective function and barrier function is a linear function.The result of the calculation of minimum weight of test structures without the influence of the normal force: 200 kN with a correction effect of the normal force: 209,87 kN. Minimum weight of structure increase of 4,93%, the beam section dimension: I-beam 140x66 and column section dimension: H-rolled 125x60.The conclusion that can be drawn is the result of the calculation of the minimum weight of the structure to an increase in weight of the structure after there is a correction to the normal force due to weight function involve the effect of the bending moment does not include the influence of other body forces such as normal-shear-torque.Keywords:minimum weight, strength, rigidity,safety factor, normal forceAbstrakStruktur bangunan dibentuk oleh elemen balok dan elemen kolom.

Abstract

AbstractEenvironmental issues that caused by the production of portland cement and the development needs of the concrete casting technology, where in the last few decade scientists has started to do research and development of fly ash based - self compacting geopolymer concrete. Fly ash based - self compacting geopolymer concrete is a concrete which made of geopolymer material (fly ash) that combined with aggregate without using of portland cement. It is must have workability criteria of self compacting concrete (SCC). To get SCC’s required workability, it needs addition of extra water to the mixture of geopolymer concrete. But with the addition of extra water, the mixture of fresh geopolymer concrete could undergo dispersion and segregation, also might be affect to the chemical binding of geopolymer material. So, it needs admixture material such as superplasticizer which serves to increase workability of fresh geopolymer concrete although the amount of water content is reduced. From the description above, the author conducted a study that aims to determine the extent of the influence of water and superplasticizer on the workability and compressive strength of fly ash based -self compacting geopolymer concrete.Fly ash based- Self Compacting Geopolymer Concrete planned as follows, Fly ash (Class F) in dry condition; coarse and fine aggregates in a SSD condition; Sodium Hydroxide’s concentration is 14M; Alkaline / Fly Ash Ratio is 0.8; Doses of Viscocrete-10 are 0%, 1%, 2% and 3%; Extra Water / Fly Ash ratio are 0, 0.2, 0:25, 0.3, and 0,32; curing in an oven for 48 hours at temperature 70 °C.The maximum slump flow value according to EFNARC for Self Compacting Concrete is 67 cm that obtained on the addition of 3% superplasticizer and the ratio of extra water / fly ash is 0.3. Filling ability and viscosity specified in the V-Funnel test is 9.50 seconds. The test results of passing ability using the L-shaped box shows blocking ratio H2 / H1 is 0.83 seconds. Extra Water on Geopolymer Concrete provide significant impact on the slump flow value. Addition of extra water 0.3 is already getting slump flow value required by EFNARC for self compacting concrete ( 67 cm > 65 cm). The optimum composition in terms of qualified workability of Self Compacting Concrete and compressive strength are obtained on the addition of 3% superplasticizer and 0.3 extra water ratio. They give slump flow value at 67 cm and an average compressive strength of 16.28 MPa. So that in this composition, the concrete can be categorized as fly ash based - self compacting geopolymer concrete. The maximum compressive strength obtained on the mixing without extra water which is gives an average 30.55 MPa.Keywords: water content, superplasticizer, workability, compressive strength, Self Compacting Geopolymer Concrete

AbstractSoil residues are the result of physical and chemical weathering of the rocks beneath its formation occurred over rocks came from, so there are some specific characteristics of the type of soil residues are not in accordance with the basic concepts of soil mechanics are generally prepared by the behavior of alluvial soil . The ground color is yellowish brown residue . Overview Ratahan case in landfill sites are on sloping native land , therefore the compression on the type of soil residues need more in-depth review of the determination of the parameters of consolidationThe test sample soil residue undisturbed were taken to the Laboratory of Soil Test, Department of Civil Engineering, Polytechnic of Manado for testing the water content, test weight content, test weight type, test Atterberg limits, test seepage and testing consolidation by using the tool oedometer standard. The test results were analyzed further consolidation, so that unknown behavior of soil residue compression. The results of calculations using the tool oedometer consolidation parameters in landfill Ratahan, the voltage value preconsolidation by Casagrande method is 1.20 kg / cm2 sedangan method "Strain Energy-Log Stress" or methods Senol-Saglamer was 1.50 kg / cm2. Compression index value obtained was 0.0915; and the coefficient of volume change in average yield 0.01703 cm2 / kg. Value parameter consolidation coefficient (Cv) for the type of soil residue in a landfill Ratahan can not be known because of the relationship between deformation curve and the root of the time (method Taylor), straight sections do not do not pass at least four points of each curve loading. To graph the relationship void ratio and pressure, if drawn with a logarithmic scale and a linear scale will show a different behavior. Where on the logarithmic scale graph (e log P), produces a curve that is convex making it possible to determine the preconsolidation stress, whereas the linear scale graph preconsolidation stress can not be determined. This is caused because the history of the formation of soil residues, particularly landfill Ratahan not through the deposition process and the process of consolidation as the alluvial soil.The results of the use of methods Casagrande method Senol - Saglamer for preconsolidation voltage values of 12 sites experienced an average difference of about 18.80 % . In the selection method for the determination preconsolidation stress is by using the " Strain Energy -Log Stress " ( Senol - Saglamer method , because this method has a better correlation coefficient , which is 90 % -92 % compared with the methods Casagrande 77 % -82 % ( Senol & Saglamer et.al. , 2000) .Keywords: soil residu, land fill,pre-consolidation, consolidation, Casagrande method, Senol-Saglamer method

Abstract

Abstract In the process of normal concrete casting is often to experience constraints due to the distance between the reinforcement is too dense, so it can resulting segregation. Therefore the last few years started to develop Self Compacting Concrete (SCC). SCC is a concrete that is able to solidify themselves with fairly high of slump. In contrast to normal concrete, the composition of cement that needed in the mix design of SCC more than the normal concrete’s. This is also often used as research to find an additives for cement replacement which is appropriate to the nature and characteristics of the cement itself. Fly ash is a waste remnants of coal combustion, an inorganic oxide material that have forming properties such as cement and high water binding capacity. So that the fly ash become a potential material to replace cement in high volume (more than 50%). To obtain the desired strength of concrete there are several factors that must be considered, one of which is the concrete curing. So the researchers conducted a study that aims to observe the effect of curing to the strength and microstructure of High Volume Fly Ash Self Compacting Concrete. Mix design of concrete used with the following composition (1) The volume of coarse aggregate approximately 50% of the volume of solid material, in this study use 40%; (2) The volume of fine aggregate approximately 40% of the volume of mortar, in this study use 48%. (3) water cementitious ratio is 0.72. (4) superplasticizer 2.5%. The volume of fly ash are 0%, 50%, 60% and 70%. Curing is done with 4 ways: Elevated Temperature in the oven for 24 hours in a temperature of 90 ° C and 60 ° C, immersion curing, and without curing. The results showed that the slump flow values increase along with the amount of volume replacement of cement with fly ash. In 60% and 70% of fly ash volume were qualified of self compacting concrete is over 65 cm. The maximum average compressive strength is found at 50% fly ash by mass is on without curing (17.30 MPa). Based on the results of SEM and EDS, It discovery that the higher temperature of treatment indicated a reduction of calcium and silica. So that the reduced of the elements calcium and silica showed reduced the major compounds builder of concrete strength.Keywords: Curing, Compressive Strength, Microstructure, High Volume Fly Ash-Self Compacting Concrete
