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.

Porous silicon layers have been synthesized on n-type (111) silicon wafers by photoelectrochemical etching (PECE) technique with etching durations of 20 and 30 min. The morphological and structural properties of bulk and porous structures were examined by using scanning electron microscopy and X-Ray diffraction, while the electrical properties were investegated by I-Vcharactristics. From SEM images, the porous silicon (PSi) layers have sponge-like structure. XRD spectra of porous silicon showing different diffraction peaks with compressive strain. I-V characteristics showed Schottkybehaviour and small leakage current
This study aims to determine the mechanical properties of a concrete mixture using Ground Granulated Blast Furnace Slag (GBFS) and crab shell powder as a substitute for cement and fine aggregate in a concrete mixture. The mechanical properties to be studied are concrete compressive strength, slump value and its density. As a specimen in this study, a concrete cylinder with a diameter of 100 mm and a height of 200 mm was used. The compressive strength of concrete was tested at 7, 14, and 28 days. The amount of GGBF and crab shell powder used in the concrete mix varies from 0%, 5%, 10%, 15% and 20% of cement and fine aggregate weight. The results of the study showed that combination of 5% crab shell powder and adding 10% GGBFS powder, can increase the compressive strength of the concrete of 5.56%.
