Compressive Strength of Concrete containing Eggshell Powder as Partial Cement Replacement

IOP Conference Series: Earth and Environmental Science, 2021
Abstract The emission of carbon dioxide by cement manufacturing has caused a negative impact on society and environment such as the greenhouse effect. Disposal of eggshell has created a lot of environmental problems due to its reusability of material is low in many industries.

Nesting behaviour influences species-specific gas exchange across avian eggshells [PDF]

, 2014
Carefully controlled gas exchange across the eggshell is essential for the development of the avian embryo. Water vapour conductance (GH2O) across the shell, typically measured as mass loss during incubation, has been demonstrated to optimally ensure the
