Potential of compost mixed with tuff and pozzolana in site restoration
Waste Management, 2015 The present research is aimed at evaluating the potential of mixtures made of different percentages of compost (10%, 20% and 30% by volume) and inorganic waste from extraction activities (tuff and pozzolana) for site restorations. The materials alone and the mixtures were characterised from a geotechnical point of view, in order to determine the ...

Caratterizzazione geotecnica della pozzolana di Orvieto
, 2006 La città di Orvieto sorge su una piastra rocciosa costituita da tufi litoidi e pozzolane, poggiante su una formazione argillosa. I fenomeni di dissesto che fin da tempi storici coinvolgono il margine della Rupe e le cavità sotterranee in essa scavate rendono necessaria un'approfondita caratterizzazione geotecnica dei materiali piroclastici.

Estimation of pozzolana content in Portland pozzolana cement
Cement and Concrete Research, 1983Abstract A simple and rapid method based on cold and dilute hydrochloric acid has been developed to determine pozzolana content in Portland pozzolana cements (PPC). The method is applicable to different types of pozzolana even in the absence of original samples of ingredients used in the production of PPC. A 5% (v/v) solution of HCl (sp. gr.
