Abstract

ABSTRACTThis study aims to get the maximum compressive strength with high quality in determining theeffect of partial replacement of cement with bentonite to the compressive strength of concrete.This study was conducted by testing the chemical composition of the bentonite by using themethod of Atomic Absorption Spectrometry (AAS) and Gravimetry that refers to the ASTM 618-03. For testing the compressive strength of concrete it was used the age variation to assess thecompressive strength of concrete using 10% of bentonite as the partial replacement for cement.There were 18 samples consisting of three cylindrical concrete samples in each age variation(the diameter was 150 mm and the height was 300 mm) and the testing was conducted at theage of 3, 7, 14, 21, 28 and 56 days. The results showed that the test of bentonite chemicalcomposition in the Chemistry Analytical Laboratory of Gadjahmada University met therequirements of pozolan chemical. The highest compressive strength at the age of 56 days andat 28 days the lowest compressive strength were 49.454 MPa and 37.119 MPa respectively.The percentage of the optimum increase of concrete obtained at the age of 28 days to 56 dayswas 33.23%. Moreover the addition of bentonite gives the effect to the workability so that thevalue of the slump was lower than the that in the planning.Keywords: Bentonite, Compressive strength, Slump

Abstract

Nowadays, Non Destructive Tests have been applied in many qualityevaluations of existing concrete structures. One of the Non Destructive Tests (NDT)is based on Ultrasonic Pulse Velocity (UPV). The use of UPV method among othersare to estimate the strength of concrete, to detect the presence of crack, to measurethe homogeneity of concrete, the thickness of concrete slab, and also to estimate thediameter of the embedded steel reinforcement. The NDT technique will apply on thisresearch. This research used 24 cylinder test samples in four groups, which werereference cylinder (SR), cylinder-1 (S-01) with 0.5 kg/m3 of fibers, cylinder-2 (S-02)with 1.0 kg/m3 of fibers and cylinder-3 (S-03) with 1.5kg/m3 of fibers. Those cylinderswere of 150 mm in diameter and 300mm in height. The Ultrasonic Pulse Velocity(UPV) test was conducted with direct test method. The data are then analyzed usingstatistical program. The test result showed that the addition of polypropylene fibersoptimum and pulse velocity were of 1kg/m3 and 3,19km/s respectively. The increasepulse velocity transmitter higher on variation of fibers 1kg/m3 is 9,12% in comparisonto reference cylinder. The statistical test indicated that the signifinance value (2-tailed test) is homogeneity sample. This means that the ultrasonic pulse velocitymethod can used to knowing of homogeneity self compacting mortar using fibers.Keyword: Homogeneity, polypropylene, Ultrasonic pulse velocity Method

Abstract

In the recent decade , the development of retaining wall construction keeps growing rapidly along the optimization of the use of available land. The main purpose of this construction is restrain the land so as not landslide Due to the load that it work in addition to the utilization of the space available. In this case study in sindu kusuma edupark project using construction type anchoring ground gravity wall. If the structure of gravity wall is not safe withstand the force that worked , then required alternative design construction of retaining wall of another appropriate. Construction retaining wall that can be used as alternatives is sheet-pile wall or commonly called Turap. The difference of gravity wall and turap lies in the stability analysis of construction and materials. Excess of sheet pile of this wall is the tough a lighter , the implementation of the gravity relatively quickly than wall, Suitable used for the drift the ground with a height was , the quality of construction uniform and more secured construction than manual for using prefabricated construction. From the analysis of stability gravity wall , we can conclude that when the structure receives of static load, Construction stability was not secure against overtuning , sliding , axial load , and broken foot structure but it still safe receives sliding and capacity stability fulfilled. When encumbered by dynamic loads, structure safe against bolsters, sliding, and soil bearing capacity.The Sheet pile wall selected as a substitute for wall gravity is prefabricated concrete Wika Beton , with type w-325 a 1000 - length: 8 m with a long as deep as 3 m of installing. The type of sheet pile used anchorage sheet pile of continuous type, with 10 mm in diameter and the distance is 3m. The Boards anchor used behind construction sheet-pile with 3m in long sized, make stability sheet-pile secure with SF = 2.Key word: Pile wall, Safety Factor

Abstract

ABSTRACTThe beam material in the construction world is designed to withstand collapse due to bending, diagonal drag, and sliding. Shear behavior in design becomes a very complex problem and is not easy to predict. However, failure due to the influence of shear forces is avoided in the design world due to damage that occurs without prior precautions, so that building users do not have the opportunity to save themselves. The study of variables that determine shear forces is a contradictory debate. One of the influential variables is the compressive strength of concrete (fc’). This work examines the correlation of compressive strength to the shear capacity of concrete beams with variations in care because there is still very little literature in Indonesia that studies the relationship of the two variables. Tests carried out on beams with reinforcement and without reinforcement which have pxlxt size is 1000x200x400 mm by getting the behavior of the point load at the center of the span (three-point load). Maintenance variations are carried out by testing in wet conditions as material representation in water construction and dry conditions for ordinary buildings. After 150 days of study, it was found that the compressive strength of concrete had a higher correlation with the strength of the concrete at the time of cracking (Vcr) than the strength of ultimate concrete (Vu). Wet conditions will produce lower strength than linear conditions with linear correlation levels of both.Keywords: concrete, compressive strength, shear strength, concrete treatment ABSTRAK Material balok dalam dunia konstruksi dirancang untuk tahan terhadap keruntuhan akibat lentur, tarik diagonal, dan geser. Parilaku geser dalam perancangan menjadi permasalahan yang sangat kompleks dan tidak mudah untuk diprediksi. Namun demikian kegagalan karena pengaruh gaya geser sangat dihindari dalam dunia perancangan dikarenakan kerusakan yang terjadi tanpa didahului dengan peringatan terlebih dahulu, sehingga pengguna bangunan tidak memiliki kesempatan untuk menyelematkan diri. Pengkajian mengenai variabel yang menentukan kekuatan geser menjadi sebuah perdebatan yang kontradiktif. Salah satu variabel yang berpengaruh adalah kekuatan tekan beton (fc’). Penelitian ini mengkaji mengenai korelasi kuat tekan terhadap kapasitas geser balok beton dengan variasi perawatan dikarenakan masih sangat sedikit literatur di Indonesia yang melakukan pengkajian hubungan kedua variabel tersebut. Pengujian dilakukan pada balok dengan tulangan dan tanpa tulangan yang memiliki ukuran pxlxt adalah 1000x200x400 mm dengan mendapatkan perilaku beban titik di pusat bentang (three-point load). Variasi perawatan dilakukan dengan melakukan pengujian pada kondisi basah sebagai representasi material pada konstruksi bangunan air dan kondisi kering untuk bangunan biasa. Setelah dilakukan pengkajian selama 150 hari diperoleh hasil bahwa kuat tekan beton memiliki korelasi lebih tinggi terhadap kekuatan beton pada saat retak (Vcr) daripada kekuatan beton ultimit (Vu). Kondisi basah akan menghasilkan kekuatan yang lebih rendah dari kondisi kering yang linier dengan tingkat korelasi keduanya. Kata kunci: beton, kuat tekan, kuat geser, perawatan beton
