In 2008, a medieval wooden shipwreck was discovered at the port of Rhodes, Greece. The party burned, presenting challenge for conservators, as uncharred, semi-charred and charred waterlogged wood were often encountered on same piece timber. seeking most appropriate conservation method this unusual material, its chemical characterization considered necessary. This study examined chemistry three ...

Floor heaving is a phenomenon that occurs in almost all mining roadways and tunnels. It can restrain the advance of heading face or cause serious problems during roadway use. The highest levels floor uplifting are observed coal mines, which reduce output even stop it altogether. intensity depends on rock type, stress mass, rocks’ mechanical properties. deformation develops when secondary state ...

The goal of the study was to characterise chemical interactions between waterlogged archaeological wood and organosilicon compounds applied for its conservation shed lights on mechanism dimensional stabilisation by chemicals. Two alkoxysilanes (methyltrimethoxysilane (3-mercaptopropyl) trimethoxysilane) a siloxane (1,3-bis(diethylamino)-3-propoxypropanol)-1,1,3,3-tetramethyldisiloxane) were sel...

The Huaguangjiao I is an ancient Chinese wooden shipwreck from the South Song Dynasty (AD 1127–1279) discovered in China Sea 1996. first phase of its conservation, desalination and desulfurization, was completed 2016. In this paper, three archaeological wood samples exhibiting different degrees deterioration No. 1 were consolidated with PEG-4000 dehydrated via freeze drying supercritical CO2 me...

The article considers changes in natural patterns of moisture transport parameters under waterlogging and lowering groundwater table, conditions filtration-anisotropic strata. nature anisotropy characteristic river sediments (alluvial, pluvial, deltaic their combinations) is the most widespread surface zone earth’s crust. Impact factors: external artificial, process drainage, affect both positi...
