Structural Concrete, EarlyView.Abstract Cold weather conditions impose substantial constraints upon the performance and long‐term resilience of concrete materials. Alkali‐activated slag (AAS) presents itself as a promising substitute, exhibiting sustained hydraulic activity even when exposed to ambient conditions characterized by low temperatures.

Bacterial healing of cracks in metakaolin‐based geopolymer concrete exposed to high temperatures
Structural Concrete, EarlyView.Abstract This study examined the bacterial healing of metakaolin‐based geopolymer concrete modified with colemanite (K) and red mud (RM) exposed to high temperatures. The metakaolin‐based geopolymer concrete samples modified with 4% K and 6% RM were prepared.

Environmental Toxicology, EarlyView.ABSTRACT Climate change and anthropogenic ignitions are intensifying wildfire frequency worldwide, elevating the risk of freshwater contamination by ash. In water, dissolved ash releases ions and other toxic constituents that increase pH and alter physicochemical conditions, while suspended ash particles may impose mechanical stress, disrupt behavior ...

Herbivore and mesocarnivore carcasses trigger divergent short‐term changes in soil properties
Journal of Animal Ecology, EarlyView.Scavengers reshape nutrient cycles in soils under carrion. Compared to herbivore carcasses, smaller but longer‐lasting carnivore remains boost nutrient levels and microbial activity in dry soils. Abstract Animal corpses act as pulses of organic matter (OM) and serve a key zoogeochemical role by providing localized nutrient inputs to soils and thereby ...
