| چکیده | ||
| یکی از راهکارهای بازیافت مواد ضایعاتی مانند لاستیک تایر و شیشه، استفاده از آن‌ها در بتن می‌باشد که علاوه بر کمک به پاک‌سازی محیط زیست، باعث برداشت کمتر از معادن طبیعی و کاهش آلودگی حاصل از تولید سیمان می‌شود. در این مقاله تاثیر جایگزینی همزمان ذرات لاستیک ضایعاتی به جای بخشی از سنگدانه ریز و پودر شیشه به جای بخشی از سیمان، بر کارایی و مشخصات مکانیکی بتن، در دمای محیط و پس از اعمال حرارت °C600، مورد بررسی قرار گرفت. برای تعیین میزان تاثیر اندازه ذرات لاستیک بر کارایی و مشخصات مکانیکی، پیش و پس از اعمال حرارت، از دو اندازه متفاوت ذرات لاستیک mm 1–0/15 و mm 5–3 استفاده شد. در کل 13 طرح اختلاط ساخته شد، که جز طرح مرجع، باقی دارای ترکیب ذرات لاستیک جایگزین ماسه در مقادیر حجمی 5% و 10%، در دو اندازه ذرات لاستیک و پودر شیشه جایگزین سیمان در مقادیر وزنی 10%، 15% و 20% بوده‌اند. برای بررسی کارایی بتن‌های دارای لاستیک و پودر شیشه از آزمایش اسلامپ استفاده شد، همچنین مقاومت‌های فشاری، کششی، نسبت مقاومت کششی به فشاری، پیش و پس از اعمال حرارت و افت وزن ناشی از اعمال حرارت، مورد بررسی قرار گرفت. برای درک رفتار مواد ضایعاتی از تصاویر میکروسکوپ الکترونی و طیف‌سنجی استفاده گردید. نتایج در هر دو حالت حرارتی نشان داد 5% لاستیک و 10% پودر شیشه، همچنین اندازه mm 5–3 ذرات لاستیک، بهترین نتایج را از نظر مقاومت‌های فشاری و کششی، در بین طرح‌های اختلاط دارای لاستیک و پودر شیشه، ارائه داده‌اند. | ||

| چکیده [English] | ||
| One of the recycling approaches for waste materials like tires and glass is to use them in concrete. In this paper, the effect of the simultaneous use of waste rubber as partial substitution of fine aggregate and glass powder as partial substitution of cement, on workability and mechanical properties, in ambient temperature and after exposure to temperature of 600 °C, is investigated. In order to evaluate the effect of rubber particle size on workability and mechanical properties, two different rubber particle sizes of 0.15-1mm and 3-5mm were used. In total, 13 mixtures were prepared. Except for the reference mixture, the rest contained a combination of rubber particles replacing fine aggregate with the percentages of 5% and 10% by volume and glass powder replacing cement with percentages of 10%, 15% and 20%. First of all, the slump test was carried out. Moreover, compressive strength and tensile strength, before and after thermal exposure, were investigated. In order to have an understanding of waste material's behavior, scanning electron microscopy and energy-dispersive X-ray spectroscopy tests were conducted. the results indicated that 5% for rubber particles, 10% for glass powder and also rubber particle size of 3-5 mm presented the best results among mixtures containing rubber and glass powder, in terms of compressive and tensile strengths. | ||
