| پودر شیشه یکی از پسماندهای جامد روزافزون در جهان است و از طرفی خاک رس معمولا نیازمند بهسازی جهت استفاده در پروژه‌های عمرانی می‌باشد. در تحقیق حاضر اصلاح پارامترهای مقاومتی خاک رس، توسط ژئوپلیمر ساخته شده با پایه پودر شیشه بازیافتی (RGP) مورد مطالعه قرار گرفت. برای این منظور آزمایش‌های مقاومت تک محوری (UCS) و نسبت باربری کالیفرنیایی (CBR) به روی نمونه‌های اصلاح شده انجام شد. زمان عمل‌آوری، درصد وزنی استفاده RGP و غلظت ماده فعال کننده (M) از جمله متغیرهای مورد بررسی در پژوهش بودند. به منظور مقایسه، آزمایش‌ها بروی نمونه‌های اصلاح شده با 10 درصد سیمان پرتلند نیز انجام گردید. نتایج افزایش ژئوپلیمر به نمونه‌های خاک نشان داد که میزان استفاده بهینه از RGP مقدار 9 درصد است. همچنین به غیر از نمونه‌های 0day در آزمایش CBR، سایر نمونه‌های UCS و CBR دارای مقدار بهینه غلظت ماده فعال کننده (NAOH) بودند که نشان دهنده تاثیر شرایط عمل‌آوری بر رفتار خاک اصلاح شده است. بررسی تصاویر عکس برداری الکترونی روبشی (SEM) حاکی از تاثیر روش اصلاحی بر توده خاک بود. مقایسه تحلیلی آزمایش‌های UCS و CBR بیانگر رابطه ریاضی میان نتایج آزمایش‌های UCS و CBR-7day با همبستگی نسبی خوب بود که با توجه به شرایط نگهداری یکسان نمونه‌ها در 7 روز اول قابل انتظار بود. همبستگی اندکی در نتایج آزمایش‌های UCS و CBR-0day مشاهده شد که علت آن تفاوت شرایط عمل‌آوری دو آزمایش در 7 روز اول بود. | ||

| چکیده [English] | ||
| Glass powder is one of the increasing solid wastes in the world, and on the other hand, clay usually needs improvement to use in construction projects. In the present study, modification of clay soil strength parameters was studied by geopolymer based on recycled glass powder (RGP). For this purpose, uniaxial strength (UCS) and California load Bearing Ratio (CBR) tests were performed on the modified specimens. Processing time, the weight percentage of used-RGP and activator concentration (M) were the studied variables in the current study. For comparison, experiments were performed on samples modified with 10% Portland cement. The addition of the geopolymer to soil samples showed that 9% of RGP was the optimal amount. Also, despite of the 0day samples in the CBR experiment, other UCS and CBR samples had the optimal amount of activator concentration (NAOH), which indicates the effect of processing conditions on the behavior of the modified soil. The assessed scanning electron imaging (SEM) images showed the effect of the corrective method on soil mass. Analytical comparison of UCS and CBR experiments indicated a mathematical relationship between the results of UCS and CBR-7day experiments associated by a good relative correlation that was predictable due to the same storage conditions of the samples in the first 7 days. Due to the different processing conditions of both tests in the first 7 days, a slight correlation was observed in the results of UCS and CBR-0day tests. | ||
