Journal of Building Engineering, 2019 Abstract Eggshell powder (ESP) may be an alternative natural sustainable supplementary cementitious material (SCM). Mortar specimens containing 0, 5, 10 and 20 wt. % of ESP as Portland cement replacements were submitted to 20, 150, 300 and 450°C.

Research on High- and Low-Temperature Characteristics of Bitumen Blended With Waste Eggshell Powder [PDF]
Materials, 2021 The sustainability of resources is presently a major global concern. Sustainable construction materials can be produced by applying biological waste to engineering. Eggshells, as biological waste, are usually dumped in landfills or discarded. This causes many environmental problems including malodor, noise pollution, and serious waste of resources.

Poultry Science, 2005 An experiment was conducted to study the effects of different eggshell temperature (EST) profiles during incubation on embryo mortality, hatchability, and embryo development. Furthermore, chicks from different EST profiles were reared under low and high housing temperatures to investigate subsequent posthatch growth and rectal temperature.

Poultry Science, 2012 Eggshell quality deterioration associated with heat stress is a well-known phenomenon. The involvement of the 28-kDa calcium-binding protein (calbindin, CaBP-D28k) localization in this failure is not clearly understood. To test a possible direct effect of ambient temperature on calbindin-D28k localization, 40 White Leghorn laying hens were housed in ...

High ambient temperature decreases eggshell thickness in Zebra Finches
Ibis, 2023Avian females can alter nest‐site selection and breeding behaviour in response to changes in ambient temperature. However, whether females alter eggshell characteristics in response to high ambient temperature is underexplored. To fill this gap, wild‐derived and domesticated Zebra Finches were bred at temperatures of 18 °C and 30 °C or 35 °C.

The Densification of Hydroxyapatite from Eggshell Waste at Different Sintering Temperature
Journal of Mechanical Engineering, 2023The outstanding biocompatibility and bioactivity properties of hydroxyapatite (HA) as a bio-implant material have garnered significant attention in prompting its extensive study. However, due to its brittleness and lower strength, its usage as a bone implant in load-bearing regions of biomedical applications is limited.

Brewing MnWO4 microspheres on the eggshell membrane at room temperature
Russian Journal of Inorganic Chemistry, 2009Manganese tungstate microspheres were successfully fabricated using biomimetic process on living eggshell membrane (ESM) at room temperature. The microspheres were assembled by nanolamellar subunits, which are in the size with lengths of 1–2 nm, widths of 0.1–0.2 nm and thicknesses of 15–20 nm.

Effects of egg washing and storage temperature on the quality of eggshell cuticle and eggs
Food Chemistry, 2016This study investigated the quality of washed and unwashed eggs stored at 7°C (WC and UC for washed and unwashed eggs, respectively) and 25°C (WR and UR for washed and unwashed eggs, respectively) for 4weeks. The results show that the Haugh unit, albumin pH, thick albumin ratio, yolk index, air cell size, and S-ovalbumin content of UC were ...

Poultry Science, 2016 The aim of the current study was to determine the effects of different eggshell temperatures (EST); low (33.3 to 36.7°C), control (37.8 to 38.2°C), and high (38.9 to 40.0°C) during 10 to 18 days of incubation on welfare status including foot pad dermatitis (FPD), hock dermatitis (HD) and feathering status, and gait score in broilers.

Selectivity of SO2 and H2S removal by ethanol-treated calcined eggshell at low temperature
Environmental Science and Pollution Research, 2020Eggshell is a food waste produced worldwide in substantial amount with very limited recycling activity. In this study, the potential of ethanol-treated calcined eggshell was tested as sorbent for SO2 and H2S. Three variables were selected in the preparation of sorbents via response surface methodology (RSM), i.e., concentration of ethanol in water (50%,
