| هدف این مقاله بررسی تأثیر افزودن الیاف بازالت بر روانی، زمان گیرش، جمع‌شدگی خشک و مقاومت‌های فشاری و خمشی ملات‌های ژئوپلیمری دو جزئی عمل‌آوری شده در دمای محیط و حاوی روباره کوره آهن‌گدازی و گل سرخ است. بدین منظور، ملات‌های ژئوپلیمری مسلح شده به الیاف بازالت به مقدار 0.25، 0.50، و 0.75 درصد حجمی از مواد پایه در مقایسه با ملات پلیمری بدون الیاف ساخته شد. جهت فعال‌سازی مواد پایه از نسبت وزنی یکسان از محلول سود 4 مولار و آب شیشه استفاده گردید. همچنین برای نخستین بار مقاومت‌های فشاری و خمشی باقیمانده این ملات‌های ژئوپلیمری در حرارت‌های بالا اندازه‌گیری و بررسی شد. بدین منظور ملات‌های ژئوپلیمری در معرض سه رژیم حرارتی شامل دمای 600 درجه سانتی‌گراد به مدت 60 دقیقه و نیز دمای 600 و 800 درجه سانتی‌گراد به مدت 90 دقیقه قرار گرفتند. نتایج نشان داد که افزودن 0.5 درصد الیاف بازالت نه تنها می‌تواند به نحو مطلوبی مشکل جمع‌شدگی خشک ملات‌های ژئوپلیمری را رفع نماید، بلکه استفاده از این مقدار الیاف بازالت می‌تواند مقاومت‌های فشاری و خمشی ملات‌های ژئوپلیمری را هم در دمای محیط و هم در درجه حرارت‌های بالا بهبود و ارتقا دهد. همچنین جهت بررسی ساختار فازی ژئوپلیمرها در درجه حرارت‌های بالا آزمایش پراش اشعه ایکس (XRD) روی آن‌ها انجام شد. نتایج نشان داد که ژئوپلیمرها در این دما دچار یک تغییر از فاز حالت آمورف به کریستالی می‌شوند. | ||

| The purpose of this research is to investigate the effect of adding basalt fibers on flowability, setting time, shrinkage and compressive and flexural strengths of geopolymer mortar cured at ambient temperature. The ground granulated blast-furnace slag and red mud, which are the waste products of iron and aluminum factories, were used as aluminosilicate base materials in the geopolymer mortar mix design. Also, for the first time, the residual compressive and flexural strengths of geopolymeric mortars containing basalt fibers exposed to three thermal regimes including 600°C for 60 minutes and 600°C and 800°C for 90 minutes were measured and investigated. XRD tests revealed that geopolymers undergo a structural phase change from amorphous to crystalline at high temperatures. In addition, the results showed that adding 0.5% of basalt fibers as an optimal percentage, not only can solve the problem of drying shrinkage of geopolymer mortars, but also the use of this amount of basalt fibers can increase the compressive and flexural strength of geopolymer mortars both at ambient temperature and at high temperatures. Therefore, geopolymer mortar containing 0.5% basalt fibers, in addition to having positive environmental aspects, can be used as a repair mortar with high mechanical characteristics and also suitable resistant to high temperature for the repair and retrofit of concrete structures. | ||
