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...
the effect of genre-based teaching on reading comprehension of literary texts
تحقیق حاضر به بررسی کاربرد روش ژانر-محور را در محیط آموزش زبان عمومی می پردازد.روش ژانر-محور به زبان آموزان کمک میکند که در زمینه خوانش پیشرفت کنند. بعضی از محققین معتقد اند که روش تدریس ژانر-محور به تدریج به زبان آموزان کمک می کند تا در درک ژانر های مختلف مهارت یابند (هایلند 2004).همچنین امروزه توجه روز افزونی به اهمیت استفاده از ادبیات در برنامه آموزشی زبان انگلیسی (esl/efl ) شده است. زمانی ک...
15 صفحه اولEffect of Synthesis Parameters on the Compressive Strength of Fly Ash Based Geopolymer Concrete
The paper presents the effect of different synthesis parameters, such as (a) fly ash to alkaline solution ratio, (b) concentration of NaOH solution, (c) concentration of sodium silicate solution, (d) geopolymer solids to water ratio and (e) sodium silicate to sodium hydroxide solution ratio, on the compressive strength of geopolymer concrete synthesized from fly ash of Indian origin. It is obse...
متن کاملFactors Influencing Compressive Strength of Geopolymer Concrete
To study effects of several factors on the properties of fly ash based geopolymer concrete on the compressive strength and also the cost comparison with the normal concrete. The test variables were molarities of sodium hydroxide(NaOH) 8M,14M and 16M, ratio of NaOH to sodium silicate (Na2SiO3) 1, 1.5, 2 and 2.5, alkaline liquid to fly ash ratio 0.35 and 0.40 and replacement of water in Na2SiO3 s...
متن کاملChromate Adsorption by Kaolinite
Chromate (CrO4 2-) adsorption was investigated on kaolinite (0.2-2 ~m) saturated with NaC104 over a range of pH. Adsorption increased with decreasing pH because of protonation of chromate and/ or variable charge sites on kaolinite. Chemical pretreatment to remove noncrystalline and crystalline oxide contaminants affected the magnitude ofCrO42adsorption, but not the pH range over which CrO42adso...
