Improvement of physical, mechanical and strength behavior of cohesive soils with natural pozzolana and brick dust [PDF]

open access: yes, 2020
This research project seeks to improve soil properties through experimentation with geotechnical purposes. For this, will be used natural volcanic pozzolana in 5%, 10%, 15% and brick dust in 10% giving it a second reuse.

Contribution of natural pozzolana to durability of high performance concrete in chloride environment

open access: yes, 2011
This paper presents mechanical and durability properties of natural pozzolana high performance concrete. Concrete’s these properties in a chloride environment improved by replacing 7.5% cement with pozzolana of 9600 cm2/g fineness.

Understanding plaster production in Palaepaphos–Hadjiabdoullah, Cyprus, during the Cypro‐Classical period

open access: yesArchaeometry, Volume 67, Issue 6, Page 1437-1452, December 2025.
Abstract This article discusses the results of analytical work on wall and floor plaster from a secular monument excavated on the plateau of Palaepaphos–Hadjiabdoullah (Cyprus). Excavated within the frame of the Palaepaphos Urban Landscape Project (PULP), funded by the University of Cyprus since 2006, the monument is an extensive multifunction workshop
