the effect of taftan pozzolan on the compressive strength of concrete in the environmental conditions of oman sea (chabahar port)
cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...

فرض کنیمr یک حلقه تعویض پذیر ویکدار موضعی باشدو(j(r رایکال جیکوبسن r و(z(r مجموعه مقسوم علیه های صفر حلقه r باشد.گوییم r یک حلقه z- موضعی است هرگاه j(r)^2=. .همچنین برای یک حلقه تعویض پذیر r فرض کنیم c یک عنصر ناصفر از (z( r باشد با این خاصیت که cz( r)=0 گوییم حلقه موضعی r یک حلقه c - موضعی است هرگاه و{0 و z(r)^2={cو z(r)^3=0, نیز xz( r)=0 نتیجه دهد که x عضو {c,0 } است. در این پایان نامه ساخ...
Flexural strength of the joint between glass-infiltrated alumina frames and the alumina-magnesia modifier.
PURPOSE The purpose of the present study was to evaluate the flexural strength of the joint between glass-infiltrated alumina frames and the experimental adjusting agent (MA modifier) that contains alumina and magnesia. METHODS A commercially available adjusting agent (Optimizer), a slurry of alumina powder (Alumina modifier), and a bulk specimen (joint-free alumina) were used as controls. Be...
متن کاملScale Effect on the Shear Strength of Reinforced Concrete Columns with Termination of Main Reinforcements
A number of RC bridge columns which are similar with the columns which suffered extensive damage during the 1995 Kobe, Japan earthquake due to premature shear failure resulting from the termination of longitudinal reinforcements with insufficient development and the lack of shear reinforcements still exist. To improve the seismic performance, some of them were retrofitted. Evaluation of shear s...
متن کاملThreshold strength and residual stress analysis of zirconia–alumina laminates
We dedicate this work to Wolfgang Pompe, a very good friend and a good friend of the Materials Faculty at UCSB where he and his wife, Gisela, shared their lives and fellowship. Three different zirconia–alumina laminates, AZ50, AZ80, and AZ95, were fabricated via tape-casting thick Zr(3Y)O2 layers, dip-coating the zirconia tapes in a slurry containing a mixture of zirconia and alumina, stacking ...
