The Effect of Different Curing Methods on the Compressive Strength of Eggshell Concrete
Indian Journal of Science and Technology, 2017 The work assesses the effect of different curing conditions on the compressive strength of the eggshell concrete. Two different qualities of the eggshell powder were used to make concrete with 0.45 water/cement ratio. The eggshell powders were treated as

Biotechnology in Animal Husbandry, 2004 Eggshell quality was studied in two groups of Shaver hens (300 hens per group) 30 weeks of age. All hens received a basic diet of the same composition with pulverized limestone as a source of calcium. The experimental group received 2 g of granular limestone (particle size 1.1-1.4 mm) per hen per day during one week, adding on the concentrate in the ...

Bending Deformation Behavior of Eggshell and Eggshell–Polymer Composites [PDF]
, 2023 Deformation behavior of the composite “eggshell–polymer plomb” was examined under bending. Hen eggs were taken as a biological material for experiments. It was shown that a viscoelastic polymer coating does not change the type of deformation behavior of ...

Polymorphism of the SCNN1g Gene and its Association with Eggshell Quality [PDF]
Poultry Science Journal, 2017 Eggshell quality is the main trait to assess egg quality. Marker assisted selection can be used to improve this trait. During eggshell formation, a mass of inorganic minerals is deposited. The Sodium Channel (SCNN1) gene family plays an essential role in

Evaluating the Use of Eggshell Waste Ash in High Strength Concrete [PDF]
Engineering and Technology Journal, 2021 This study aims to determine the effect of incorporating eggshell waste as partial compensation from Portland cement material on high-strength concrete mixtures' performance. The properties studied are workability, compressive and flexural strengths, water absorption, dry density, and thermal conductivity. In the same trend, the environmental impact of

Molecular and morphological analyses of avian eggshell excavated from a late thirteenth century earth oven [PDF]
, 2011 Using ancient DNA (aDNA) extracted from eggshell of the extinct moa (Aves: Dinornithiformes) we determined the species composition and number of eggs found in a late thirteenth century earth oven feature at Wairau Bar (South Island, New Zealand) - one of

Effect of Long-Term Selection for Non-Destructive Deformation on Egg Shape in White Leghorns
The Journal of Poultry Science, 2016 Several conventional traits, including eggshell thickness, are commonly being improved genetically as a means to increase eggshell strength. At the same time, researchers have come to recognize that factors related to egg geometry, such as egg shape ...
