Brazilian tests on layered carbonaceous slate under water-rock interaction and weathering

open access: yesYantu gongcheng xuebao, 2021
The physical-mechanical properties of transversely isotropic layered slates may be degraded due to water-rock interaction (WRI) and natural weathering, which potentially leads to the instability or collapse of tunnels, slopes and mining.

Effects of Natural Weathering on the Performance of High Solar Reflective Index Paint Surfaces Exposed in Harsh Climatic Conditions of United Arab Emirates

open access: yesBuildings, 2022
The solar reflective index (SRI) is one of the important parameters in the analysis of a building’s energy and thermal performance, especially for “cool” reflective paints or coatings and also for cool roof membranes.

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 ...

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 ...
