Abstract

Surakarta is one of the cities in Java island with a high population growth rate, triggering the increase in the construction, especially for high-rise buildings. The city is close to several earthquake sources, causing a high level of seismic hazard. One of the main parameters of earthquake resistant building design is the value of peak ground acceleration at surface level. It is obtained by multiplying the peak ground acceleration in the bedrock by a multiplier factor that depends on the site class conditions of the location. A previous study has been conducted in 2015 using 32 boreholes indicating that around 19.5% of Surakarta area is classified as SC (hard soil), and 80.5% of the rest is SD (medium soil). To increase the accuracy, another 31 additional boreholes data are adopted. The new result shows that Surakarta is divided into three different seismic site class. Around 4.80% the area is classified as SC (hard soil), 94.50% is SD (medium soil), and 0,70% is SE (soft soil). The southern part of Surakarta has a higher level of vulnerability to earthquakes, especially in the border area between Banjarsari, Laweyan, and Serengan subdistricts which have a SE (soft soil) seismic site class.

Abstract

Pile strength is widely used as a solution to the problem of road pavement on soft soil, because it can reduce vertical displacement due to the load on it and increase the safety factor value. This research analyses the vertical displacement, safety factor, effective stress and bearing capacity of the embankment on soft soil using the finite element method so the results can approach the original conditions in the field. The pile variations used are pile size variations 20x20 cm2; 25x25 cm2; and 30x30 cm2 with a square shape, variations in the distance between the piles 1,60 m; 1,80 m; 2,00 m; and 2,20 m, the depth variations 15,00 m; and 20,00 m. Loading uses truck loads based on RSNI T-14-2004 and the road classification is artery IA. The results of the analysis show that pile strength with a size 20x20 cm2, the distance between pile is 1,60 m and the depth of the piles 20 m can reduce the vertical displacement by 71,31% and increase the safety factor by 123,25%.

Abstract

The use of concrete material which dominates Indonesian construction industry is not only because its compilers are easy to get, but also because it has high durability. Anyhow, concrete structure might have high risk of damage in aggressive region and open space. Sulfate attack will form calcium sulfoaluminate where the volume of calcium aluminate is higher than concrete’s, so its volume increases and damages the connection between aggregate and cement which work as bonding. One of applicative and easy-to-get technology in preventing the effect of sulfate attack is by using additional material, pozzolan. It consists of fly ash and Blast Furnace Cement BFC which come from iron ore refining process. This research aims at finding out the effect of sea water in immersion phase and age variation towards compressive strength, split strength, flexural tensile strength and concrete permeability as well as the depth of chloride ion infiltration in normal concrete by adding fly ash. Chloride ion infiltration testing is done by soaking 150x150x150 mm cube using sea water with various period for 28, 60 and 90 days and then it will be sprayed by AgNO3 solution to know the depth of absorbed chloride ion infiltration. Chloride ion infiltration of concrete using sea water happens in 0-1.4 cm depth up to 90 days management. The addition of fly ash 12.5% makes the depth of chloride ion infiltration become smaller than using OPC for each immersion age variation.

Abstract

Concrete surface temperature changes on active thermography testing process using a halogen lamp will occur in a relatively short time. These changes are very useful in the image interpretation process which relies on changes in thermal contrast to determine the internal conditions of reinforced concrete. This research aims to determine the time interval dominance concrete surface temperature changes due to changes in object distance to the heat source as the excitation source of heat. Tests carried out in the room, so that the concrete surface temperature changes due to the effects of wind are considered small. Measurement of the temperature of the concrete surface due to the heating and cooling process using thermocouples and thermography methods. Halogen lamps are used as a source of heat excitation placed at various distances (dobj), namely 20 cm; 30 cm and 40 cm. The distance between the halogen lamp axles in this study was 30 cm. The dimensions of the test object were used 10 cm x 10 cm x 15 cm with a concrete quality of 20 MPa. The frequency percentage is analyzed according to the amount of data with the same time interval for the change in surface temperature at each distance of the specimen from the heat source. The results showed that the change in the distance of the specimen to the heat source up to 40 cm had a quite small difference, but the increase in the distance between the test object and the heat source tended to decrease the dominance of changes in the temperature of the concrete surface. The average dominance of changes in the temperature of the concrete surface is almost above 75% of the temperature change occurs at the smallest interval of the measuring instrument used, namely 1 second using a thermocouple and 0,133 seconds using the thermography method. The highest percentage shows that changes in surface temperature often occur in the range of time intervals. So based on this analysis without reviewing aspects of the distribution pattern of the data, can be concluded that the surface temperature testing of concrete by using active thermography in the room had to use measuring devices that can record temperature changes every interval of 0.133 seconds. This shows that the change in the temperature of the concrete surface during active thermography testing, the setting of the test instrument for measuring temperature changes is used in that time interval.

Abstract

The construction industry is an important thing to support the development of a country. In concrete construction, quality, strength, and durability of concrete are the main requirements of all. In urban tropical countries, carbonation is one of the essential factors that affect the durability of concrete, and it may cause corrosion of reinforced steel in concrete. Therefore, high strength self-compacting concrete may be expected as the solution, improved by pozzolanic additions, metakaolin with substitution dosage at 10%; 12,5%; 15%; 17,5%; and 20%. This study purposed to determine the effect of metakaolin and its optimum dosage to improve high strength self-compacting concrete quality on its carbonation rates. This study was done by using experimental methods. It needs a plain cylindrical concrete with 75 mm diameter and 150 mm height, and testing by SNI 03-6468-2000, EFNARC 2002, and SEM-PUPR 25-2015. The carbonation test is done using accelerated laboratory carbonation in Structures and Materials Laboratory, Faculty of Engineering, Universitas Sebelas Maret by soaking the specimens in a 4% carbonate solution for 15 days, 37 days, and 51 days, proceeded by splitting using CTM, and spray it using a 1% phenolphthalein indicator to determine its carbonation depth. Based on the results, metakaolin might improve concrete quality by reducing its carbonation rates by 15% substitution dosage of cement content, with a nominal atmospheric carbonation coefficient 3,71 mm/year½, reduced 44,41% from HSSCC without metakaolin substitution. Metakaolin addition might reduce fresh concrete's workability and fulfill self-compacting concrete requirements specified by EFNARC 2002.

Abstract

Plasticine is an artificial material made from solids such as gypsum, lime, mixed with petroleum jelly or micro wax and acid fat. The properties of plasticine are likely similar to natural clay and is influenced by oil content. The information about mechanical properties of plasticine is still very rare, and as such the study on it is riquired and must be conducted intensively. The preliminary laboratory study has been conducted to understand the behaviour of plasticines. Microwax and petroleum jelly based plasticines were utilised with the variation of oil content, whereas kaolin clay with the variation of water content is utilised as a reference material. The study is focusing on the stress-strain behaviour for both microwax and petroleum jelly based plasticines compared to the stress-strain behaviour of kaolin clay. This paper reports the result of preliminary investigation regarding the use of plasticine as an alternative artificial material for substitution of clay in soil modeling. Some engineering properties from unconfined compression strength (UCS) test and hand penetrometer are shown. The result indicates that the stress-strain behaviour of plasticine resembles the stress-strain behaviour of kaolin clay. The plasticine is suitable as a substitute cohesive material and it has a potential to be utilised for geotechnical material modelling in the future.
