Florid cemento-osseous dysplasia: A case report
2007
Cemento-osseous dysplasias are a group of disorders known to originate from periodontal ligament tissues and involve, essentially, the same pathological process. They are usually classified, depending on their extent and radiographic appearances, into three main groups: periapical (surrounds the periapical region of teeth and are bilateral), florid (sclerotic symmetrical masses) and focal (single lesion) cemental dysplasias. Florid cemento-osseous dysplasia clearly appears to be a form of bone and cemental dysplasia that is limited to jaws. Patients do not have laboratory or radiologic evidence of bone disease in other parts of the skeleton. For the asymptomatic patient, the best management…
Inconsistencies in the pozzolanic strength activity index (SAI) for silica fume according to EN and ASTM
2014
Published version of an article in the journal: Materials and Structures. Also available from the publisher at: http://dx.doi.org/10.1617/s11527-014-0457-6 Open Access New supplementary cementitious materials claimed to possess pozzolan properties emerge frequently. This development is driven both by economic and environmental pressures. Properties of new materials are compared with those of materials already well known, such as silica fume. Several test methods are standardized for making such comparisons, regulated by both European (EN) and American (ASTM) standards. Standardization indicates that procedures are secured to make comparisons valid and informative. In this article the sensit…

Tecniche di Produzione del Cemento Traslucido
2012
The aim of the paper is to investigate different techniques used by some companies nowadays involved in the production of panels or blocks made of translucent cement. For doing that, the patents registered all over the world starting from the 2000 have been studied in deep, in order to acquire more detailed information about the techniques of production and to overcome the limits due to the lack of information about this subject that is difficult to find in literature. Particularly, patents by LitraConTM, Luccon, Lucem, Italcementi have been investigated; these last four industries are, at the moment, the only ones able to make in Europe translucent cement elements by using different techni…
