| چکیده | ||
| بتن خودتراکم به دلیل دوام، کارایی، ویسکوزیته، پایداری، قابلیت جریانپذیری و مقاومت بهعنوان یکی از جدیدترین انواع بتن است. امروزه یکی از نگرانیهای مهم در محیطزیست، دفع زبالههای جامد هستند. تسمههای بستهبندی پلاستیکی نوعی از مواد پلاستیکی هستند که پس از استفاده دور ریخته و بهعنوان ضایعات شناخته میشوند، همچنین کارخانههای معادن ذوبآهن منبع اصلی تولید ضایعات اکسید آهن هستند. در این پژوهش، از تسمههای بستهبندی پلاستیکی و ضایعات اکسید آهن در طرح مخلوط بتن خودتراکم با درصدهای مختلف (0، 0/5، 1، 1/5، 2 درصد نسبت به وزن سیمان) و (0، 5، 10، 15، 20 درصد نسبت به وزن شن) بهعنوان یک ماده افزودنی استفاده شد. برای خواص تازه و سخت شده آزمونههای بتن خودتراکم با و بدون الیاف و اکسید آهن آزمایشهای جریان اسلامپ، قیف V، جعبه L، حلقه J، جعبه Uو مقاومت فشاری، مقاومت کششی، سرعت پالس آلتراسونیک، چکش اشمیت، تأثیر دما بر مقاومت فشاری و نفوذپذیری مورد ارزیابی قرار گرفتند. نتایج آزمایشها نشان داد با افزایش درصد الیاف و ضایعات اکسید آهن در بتن خودتراکم برای نمونههای مکعبی به ترتیب مقاومت فشاری، سرعت پالس آلتراسونیک، چکش اشمیت و تأثیر دما بر مقاومت فشاری 1 روزه در عملآوری 28 روزه از محدوده 1/61 % -7/44 %، 10% - 57/5 %، 3/27 %- 9/27 % و 5/22 % -20/64 % نسبت به بتن خودتراکم (شاهد) افزایش یافت همچنین مقاومت کششی نمونههای استوانهای در عملآوری 28 روزه از محدوده 21/09 % -72/57 % نسبت به خودتراکم (شاهد) افزایش یافت. | ||

| چکیده [English] | ||
| Self-compacting concrete is one of the newest types of concrete due to its durability, efficiency, viscosity, stability, flowability, and resistance. Nowadays, one of the most important concerns in the environment is solid waste disposal. Plastic packaging belts are one of the plastic materials that are thrown away after use and are known as waste, also iron smelting factories are the main source of iron oxide waste production. This research is based on the idea of using plastic packing belts and iron oxide waste in the design of self-compacting concrete mix with different percentages (0, 0.5, 1, 1.5, 2 percent compared to the weight of cement) and ( 0, 5, 10, 15, 20% relative to the weight of sand) was added as an additive. For fresh and hardened properties of self-compacting concrete tests with and without fibers and iron oxide, slump flow tests, V funnel, L box, J ring, U box and compressive strength, tensile strength, ultrasonic pulse speed, Schmidt hammer, temperature effect They were evaluated on compressive strength and permeability. The results of the tests showed that with the increase in the percentage of fibers and iron oxide waste in self-compacting concrete for cubic samples, respectively, the compressive strength, ultrasonic pulse speed, Schmidt hammer and the effect of temperature on the 1-day compressive strength in 28-day processing from the range of 1.61% - 72.57%, 10% - 57.5%, 3.27% - 9.27% and 5.22 – 20.64% increased compared to self-compacting concrete (control) and also the tensile strength of cylindrical samples in 28 days processing. It increased from the range of 21.09%-72.57% compared to self-density (control). | ||
