| چکیده | ||
| با افزایش تقاضا برای تولید برق از انرژی هستهای و همچنین استفاده از مواد رادیواکتیو به منظور اهداف دفاعی و یا صلح آمیز، ضرورت انجام اقدامات حفاظتی جهت جلوگیری از گسترش تشعشات مضر این مواد نیز بیشتر شده است. یکی از متداولترین اقدامات جهت کارکردهای سازهای و همچنین حفاظتی، استفاده از جدارهای بتنی با قدرت بازدارندهگی و حفاظتی در برابر عبور تشعشات است. استفاده از سنگدانهی سنگین در ساخت بتن این دیوارها میتواند موجب ایجاد یک سپر حفاظتی در برابر اشعههای مضر مانند گاما و ایکس شود. سنگدانهی آهنی به دلیل عدد اتمی بالا و همچنین چگالی زیاد یکی از مواد پر کاربرد در ساخت بتن سنگین است. در این تحقیق، 25 ، 75 و 100 درصد درشتدانه بتن با سنگدانهی آهنی که دارای دانه بندی پیوسته و در محدوده درشت دانه بوده است جایگزین شده و در سن 28 روز، مقاومت فشاری و مقاومت در برابر عبور اشعهی گاما از طریق چشمه سزیم مورد ارزیابی قرار گرفته است. به منظور بهبود عملکرد مکانیکی بتن، در برخی نمونهها میکروسیلیس به میزان 10 درصد وزن سیمان نیز اضافه شده است. نتایج نشان داد که استفاده کامل از سنگدانهی آهنی به عنوان سنگدانه، موجب افزایش 38 درصدی در ضریب تضعیف خطی بتن میگردد. همچنین استفاده از میکروسیلیس هرچند در خاصیت حفاظتی بتن سنگین تاثیر کمی داشته ولی موجب بهبود مقاومت فشاری بتن سنگین تا 35 درصد شده است. | ||

| چکیده [English] | ||
| With the increase in demand for electricity generation from nuclear energy and the use of radioactive materials for defensive or peaceful purposes, the need for radiation protection from these materials has also increased. One of the most common measures for structural and protective functions is the use of concrete walls as radiation shielding. The use of heavy aggregate in concrete can create a protective shield against harmful rays such as gamma and X-rays. Due to its high atomic number and high density, iron pellets are a suitable aggregate in heavyweight concrete. In this research, 25, 75 and 100% of concrete coarse aggregates were replaced with iron pellets, which had continuous grading and were in the range of coarse aggregate. At 28 days, the compressive strength and gamma-ray shielding properties were evaluated. To improve the mechanical performance of concrete, in some samples micro-silica was added to the amount of 10% of cement weight. The results showed that replacing all aggregates with iron pellets increases the linear attenuation coefficient of concrete by 38%. Although the use of micro-silica has little effect on the shielding properties of heavyweight concrete, it has improved the compressive strength of heavyweight concrete by 35%. | ||
