Air lime mortars with addition of two types sesame cooking oil were synthesized and cured in different conditions: laboratory natural climatic conditions the Pasargadae Persepolis World Heritage Sites. For laboratory, oils mortar induced hydrophobic effects, but it adversely affected on permeability values carbonation rates. However, air site demonstrated increment their hydrophobicity superfic...

Ramped pyrolysis radiocarbon dating was carried out on lime lumps from what believed to be the oldest remains of Turku Cathedral, Finland, first sacristy. Lumps extracted bulk mortar five sampling locations were analysed. For each sample, 5–6 fractions CO2 different temperature dated. One samples exhibited significant contamination for its lowest fractions. remaining samples, age-temperature pr...

This research deals with the study and modification of the initial process used by the General Electric Silicones plant to produce a useful material from the hazardous waste it generates. The generation and treatment of the waste is given in a brief overview. Samples taken at various stages in the industrial process were characterized by chemical and physical analyses. Results showed that amorp...

This paper investigates the influence of adding vegetal fibers on thermal and acoustic performance based natural hydraulic lime. Mortar samples with 10% weight were fabricated water to obtain easily workable mortars good consistency; their was compared mortar without fibers. The different types (rice husk, spelt bran, Khorasan (turanicum) wheat chaff) size (as-found ground form). Thermal measur...

The 15th century cross-vaults of the medieval Modena Cathedral (UNESCO site) consist intricate patches different masonry portions bound by three types lime mortars and at least two gypsum mortars. Such anomalous structure suggests multiple repair works over time after damaging earthquakes.The absolute dating (14C) bricks (TL) integrated with pollen record allowed to clarify construction restora...

Abstract The study aims at defining and characterizing a specific restoration mortar for archaeological masonry structures made with traditional materials to assess the suitability of mixture compared other mortars; such goal is crucial develop define interventions in sites. was defined ensure compatibility ancient following frequently adopted recommendations site, specifically by using: (1) ra...
