The Effects of Natural Weathering on Color Stability of Impregnated and Varnished Wood Materials

open access: yesAdvances in Materials Science and Engineering, 2015
The aim of this study was to investigate effects of natural weathering on color stability of Scots pine (Pinus sylvestris L.) and Oriental beech (Fagus orientalis L.) impregnated with some chemicals [tanalith-E (TN-E), adolit-KD5 (AD-KD5), and chromated ...

Impact of nitrogenous fertilizers on carbonate dissolution in small agricultural catchments: Implications for weathering CO2 uptake at regional and global scales [PDF]

open access: yes, 2008
The goal of this study was to highlight the occurrence of an additional proton-promoted weathering pathway of carbonate rocks in agricultural areas where N-fertilizers are extensively spread, and to estimate its consequences on riverine alkalinity and ...

Performance of Spray-Dried Nanofibrillated Cellulose as Wood Varnish Reinforcement in Outdoor Environment [PDF]

open access: yesBrazilian Archives of Biology and Technology
The outdoor use of wood can be improved by coating the wood surface with varnish to reduce the effects of natural weathering. However, some varnishes quickly lose their ability to protect wood, and nanoscale additives have been used to mitigate this ...

Sedimentary Responses to Climate Changes and Human Activities Over the Past 7400 Years in the Western Sunda Shelf

open access: yesFrontiers in Earth Science, 2021
High-resolution records of grain size, major and trace elements, and Sr-Nd isotopes of Core K17 from the western Sunda Shelf were investigated to evaluate the response of weathering and terrigenous input to climatic changes and human activities over the ...

The urban heat island effect on frost damage of natural building stones [PDF]

open access: yes, 2019
Climate plays a major role in the weathering of building stones. This study specifically investigates the influence of the urban heat island (UHI)in Ghent, Belgium,on freeze-thaw (F-T) weathering ofnatural building stonesand their ...

Modeling the evolution of natural cliffs subject to weathering. 2, Discrete element approach [PDF]

open access: yes, 2011
The evolution of slopes subjected to weathering has been modeled by assuming Mohr-Coulomb behavior and by using a numerical approach based on the discrete element method (DEM).

Effect of natural weathering on water absorption and pore size distribution in thermally modified wood determined by nuclear magnetic resonance

open access: yesCellulose, 2020
Thermally modified wood (TMW) is widely used in outdoor applications due to its advanced properties towards weathering stresses. Although the structure changes of TMW from weather factors have been reported, investigation of the quantitative analysis of ...

Re-weathering of stabilized clay shale with Portland cement behavior [PDF]

open access: yesMATEC Web of Conferences, 2019
Clay shale is a claystone which in fresh condition has a very high shear strength. When it reacts with the atmosphere or hydrosphere it will weather so that the shear strength of clay shale will drop drastically. The weathering potential of clay shale is
