Influence of content of coal ash on performance of cement-coal ash slurry [PDF]
AIP Conference Proceedings, 2017 To investigate the influence of content of coal ash on performance of cement-coal ash slurry, slump test and rheological test were conducted to evaluate the slurry rheology comprehensively. In the case of the cement dosage unchanged and 57% concentration of slurry, the change effect of coal ash content in 62.5%~87.5% on rheology, bleeding rate ...

Sedimentary Mercury Enrichments as a Tracer of Large Igneous Province Volcanism
Geophysical Monograph Series, Page 247-262., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.
