ABSTRACT A significant portion of existing reinforced concrete (RC) structures in seismically active regions was constructed prior to the adoption of modern seismic design standards, leaving them highly susceptible to earthquake‐induced damage. The vulnerabilities of these structures, often exacerbated by material degradation, have been starkly ...

Permanent Cement Mortar Form Systems
강재거푸집은 근래에 많이 사용되는 거푸집으로서 콘크리트의 완성면이 깨끗하고, 강성과 열전도성이 높지만 초기투자비가 과다하고, 부재의 조립과 해체, 운반을 인력에 의존하므로 시공속도가 느리고, 인력수급상황에 민감하며, 현장에서 가공이 어렵고, 해체작업이 반드시 필요하다는 단점이 있다. 합판거푸집은 콘크리트의 완성면이 깨끗하고, 목재에 비해 설치속도가 빠르며, 가공성과 전용성이 좋지만, 내수성이 불충분하며, 합판의 표면이 취약하여 쉽게 손상되며, 해체작업을 필요로 하는 단점이 있다.

ABSTRACT This paper presents the results of minero‐petrographic and chemical analyses of pottery and potential local raw materials from Ustica, a small volcanic island off the coast of Palermo (Sicily), inhabited during the Middle Neolithic. Typologically, the pottery shows cultural connections to the Bicromica and Serra d'Alto traditions, linking ...

The Behaviour of Finely Ground Bottom Ash in Portland Cement
The aim of this project was to assess the effects of finely ground MSWI bottom ash in Portland cement. Mortar mixes were prepared with 10% and 40% replacement of cement by ground IBA and then tested with regards to their material composition and ...

ABSTRACT This study presents new evidence for the early use of lime mortar during the Early Iron Age at the Piscina Torta site (Ostia, Italy), situated on the earliest Holocene beach ridges in the southern Tiber delta. The site, which was earlier described as a briquetage site, dates from between the late 8th and 6th century BCE and consists of a large
