use of eggshell as additive in concrete. Patent WOA1 Concrete additive, Concrete additive, the use of concrete additives of this type, and concrete mixtures containing these concrete additives WO A1. Abstract.
#0183;#32;In bone metabolism and the formation especially in bone substitution, calcium as basic module is of high importance. Different studies have shown that the use of eggshells as a bone substitute material is a promising and inexpensive alternative. In this in vitro study, the effects of eggshell granulate and calcium carbonate towards primary bovine osteoblasts were investigated.

Eggshell as an additive in concrete mix UMP . Besides that, concrete with 5% eggshell additive achieve the highest compressive strength which is 28 N/mm2. The eggshell concrete also improves in flexural strength which is the highest strength is N/mm2 and water penetration test produce a best of performance with lower depth at 14 mm only
An investigation on the performance of eggshell in concrete has been tested and carried out. Four proportions of concrete specimens were used in this research which is 0%, 5%, 10%, and 15%. In this concrete the material was used are Portland cement, chicken eggshell, coarse aggregate, fine aggregate, and optimum of water. The maximum size of the coarse aggregate is 20 mm and sizes of eggshell

Raw hen eggshell powder, a calcium carbonate source, was used as a biofiller in the natural rubber latex compound and latex glove film formation via dipping process. The powder was anticipated to improve the physical (smoothness and thickness of film) and mechanical properties (tensile strength and elongation at break) of latex film and to reduce the extractable protein content on film surface.
