Technology Reports of Kansai University (ISSN: 04532198) is a monthly peer-reviewed and open-access international Journal. It was first built in 1959 and officially in 1975 till now by kansai university, japan. The journal covers all sort of engineering topic, mathematics and physics. Technology Reports of Kansai University (TRKU) was closed access journal until 2017. After that TRKU became open access journal. TRKU is a scopus indexed journal and directly run by faculty of engineering, kansai university.
Technology Reports of Kansai University (ISSN: 04532198) is a peer-reviewed journal. The journal covers all sort of engineering topic as well as mathematics and physics. the journal's scopes are
in the following fields but not limited to:
The expansive soil condition will be very complicate for the engineers to make the material mix over it, however it causes a damage risk for the different rigid construction over it due to the soil expanding and shrinking that is very affected by the water content and soil layer. This research intends to investigate the effect of increasing the cement material to the process of soil expanding and shrinking. The laboratory work of index property test is needed for knowing and classifying the soil type that included the CH class based on the AASHTO classification system including the A-7-6. Soil under this class condition is generally very expansive. The measurement of Atterberg limit, Compaction, CBR, and UCS test are used for evaluating the soil properties, This researh make a trial to know the level of Compaction, CBR, UCS of the expansive soil characteristic that is mixed with the different product of cement with the optimal percentage composition. The result shows that the level of expansive soil stabilization is increasing the strength
Digital Outcrop model (DOM) is a three-dimensional model produced through image/photo data processing, therefore, it tends to provide a precise picture of rock outcrops or geological features. The use of this method have been discussed in some studies, however, research on the analysis is yet to be statistically compared to direct measurement data in the field. This research was carried out on granitic basement rocks in the Indragiri River, Muaro Silokek, West Sumatra with an area of 510 m x 19 m. Data was obtained by comparing the fracture characteristics in DOM and five scanline-windows scan locations with dimensions of 500 cm x 200 cm. Based on the fracture orientation spread over the DOM, there are four domain segmentations with three main orientation directions namely NNW-SSE, NE-SW, and ENE-WSW which are part of the Takung Fault. The results showed that by statistically analyzing the scanline - windows scan data, the direction and dip of the shear fracture is relatively similar to the fracture analysis on the DOM, with a measurement difference of ± 8°
