Impact of Fiber Reinforcement on Deformation Characteristics of Cemented Sand-Gravel Mixtures
This paper describes triaxial compression tests conducted to determine the effect of fiber inclusion on stiffness and deformation characteristics of sand-gravel mixtures. Tested soil was a mixture of Babolsar sand from the shores of the Caspian Sea and Karaj River gravel. Portland cement was used as the cementing agent and fibers 12mm in length and 0.023mm in diameter at 0%, 0.5% and 1.0% were ...
متن کاملstiffness and deformation characteristics of a cemented gravely sand
the deformation and stiffness characteristics of a cemented gravely sand was investigated using triaxial equipment. the triaxial tests were conducted in both dry and saturated undrained conditions. artificially cemented samples are prepared using gypsum plaster as the cementing agent. the plaster was mixed with the base soil at the weight percentages of 1.5, 3, 4.5 and 6. the applied confining ...
متن کاملEffects of Using Eggshell Waste as a Calcium Source in the Diet of Rhode Island Red Roosters on Semen Quality, Gonadal Development, Plasma Calcium and Bone Status
A 10 wk trial was conducted to investigate the effect of using ground, sterilized eggshell as a calcium source in breeder male diets. Live performance, semen quality, gonadal and visceral organ characteristics, plasma calcium concentration and bone mineralization were evaluated. Forty-five Rhode Island Red cockerels aged 25 wk were caged individually in a conventional open-sided house. The bird...
متن کاملEngineering Tough Materials: Biomimetic Eggshell
This final report summarizes the work completed on the two year pilot project, which concluded 31 July 2016. The first section summarizes the two previous reports to place the current work in context. Two new research results sections are included here. The first concerns the use of a synthetic peptide, mimicking natural eggshell protein believed to be influential in biomineralization, to exami...
متن کاملEffect of lindane on eggshell characteristics and calcium level in the domestic duck.
Adult laying domestic ducks (Anas platyrhynchos domesticus) were forced fed lindane (gamma-hexachlorocyclohexane) 20 mg/kg body weight daily, thrice/week and twice/week for 8 weeks. Significant shell thinning (18-21%) was observed in ducks with daily and thrice/week lindane feeding. SEM studies of thinned eggshells revealed reduced and tightly clustered mammillae with apparent decrease in inter...
