Utilizing rice husk ash as a bio-waste material in geopolymer composites with aluminium oxide


Thirukumaran. T and Vivek. S et al. View all


Permanent damages and spalling occur in conventional concrete due to high temperatures. Also concrete loses its compressive strength amounting to about 50 to 75% of the original strength as reported in most of the research works. As opting for high grade of concrete leads to higher costs and emits...

Effect of biochar on tungsten bioavailability and uptake grown in a soil with artificially tungsten contaminated


Wei-Jiang Chen,Ming Chen et al. View all

Environmental Toxicology and Biogeochemistry of Ecosystems

Tungsten (W) is an emerging contaminant because of its potential toxicity to humans, and biochar (BC) is widely used for soil heavy metal remediation. However, W-biochar-plant interactions remain unknown. The objective of the study was to evaluate the effect of rice-husk BC on W uptake by lettuce...
