The durability of SHCC with alkali treated curaua fiber exposed to natural weathering

Cement and Concrete Composites, 2018
This work presents the durability studies carried on strain-hardening cement-based composites reinforced with 4% of 40 mm alkali treated natural curaua fiber. The collected results present the influence of natural weathering periods of 6 and 12 months on

An investigation of surface properties of thermally modified wood during natural weathering for 48 months

Measurement: Journal of the International Measurement Confederation, 2018
Weathering period and exposure conditions can affect the degradation rate of wood surfaces. Longer weathering exposure periods are more reliable for end-use performance evaluations, and therefore it is desirable to investigate the role of long exposure ...

Natural selection: Fair weather cooperators

Current Biology, 2022
An impressive long-term study of Greater Ani birds reveals fluctuating selection for group size. In wet years, with abundant food, larger groups enjoy greater protection from predators. In dry years, however, larger groups suffer greater nestling mortality relative to smaller groups.

The impact of natural weathering and mining on heavy metal accumulation in the karst areas of the Pearl River Basin, China.

Science of the Total Environment, 2020
This paper presents the heavy metal content in river water, sediment and bedrock in the karst area of the Pearl River Basin in China to evaluate the long-term impact of natural weathering and mining on the ecological environment. The results show that Cd

Characterization of Naturally Weathered Polypropylene Plates

Journal of Macromolecular Science, Part A, 2006
The natural outdoor ageing of thick plates of isotactic polypropylene is investigated. Different techniques (infrared spectroscopy, thermal analysis, scanning electron microscopy, and mechanical tests) are used in order to obtain a comprehensive view of the modifications occurring during the environmental ageing.

Natural weathering of coal

Fuel, 1984
Abstract The effects of weathering on the mean maximum vitrinite reflectance, moisture content, and low-temperature ash mineralogy of the low volatile bituminous, Lower Mississippian Price Formation coals of southwest Virginia were determined on samples from depth profiles of three weathered coal beds.
