چکیده

ژئوپلیمرها به عنوان یک بتن بدون سیمان توّجه پژوهشگران را در سال‌‌های اخیر به خود جلب کرده است. در ساخت این نوع بتن‌‌ها به جای سیمان از مواد مختلفی مانند میکروسیلیس، متاکائولن، زئولیت و ... استفاده می‌‌شود. برای تشکیل مادۀ چسباننده به کار گرفتن محلول‌‌های شیمیایی برای تکمیل فرآیند ژئوپلیمریزاسیون ضروری است. پژوهش حاضر به بررسی دوام ملات‌‌های ژئوپلیمری بر مبنای سربارۀ کورۀ آهنگدازی (GGBFS) و جایگزینی با درصدهایی از کائولن در چند مولار مختلف می‌‌پردازد. در این تحقیق از GGBFS به عنوان جایگزین سیمان و از محلول‌‌ سدیم هیدروکسید (سود) با غلظت 4 و 8 مولار و سدیم سیلیکات (آب شیشه) به عنوان محلول‌‌های شیمیایی استفاده شد. مواد پایه به صورت منفرد و ترکیبی با اجزای دیگر مخلوط بررسی شدند. بدین منظور پودر سرامیک کائولن در 50% و 75% با GGBFS مخلوط شده‌‌اند که در مجموع 12 طرح اختلاط ساخته شد. خصوصیات مورد مطالعه عبارتند از: مقاومت فشاری، نفوذ وجود یون کلر در بتن (RCMT)، مقاومت الکتریکی، درصد جذب آب، افت مقاومت فشاری و افت وزن پس از قرارگرفتن در محلول اسید سولفوریک. از مطالعۀ موارد مذکور نتایج زیر حاصل شد: استفاده از پودر کائولن و سرباره موجب کاهش مقاومت فشاری می‌‌شود و کمترین مقدار 33% در 50-SC4 مشاهده شد؛ همچنین نتایج نفوذ وجود یون کلر در بتن و کاهش وزن نمونه‌‌های ملات در محلول اسید سولفوریک حاکی از آن است که استفاده از پودر کائولن و سرباره، باعث افزایش دوام 38% در نمونه های بتنی 50-SC8 تحت شرایط تهاجم کلرایدی ناشی از کاهش نفوذپذیری می شود.

چکیده [English]

Geopolymers as cement-free concrete have attracted the attention of researchers in recent years. In making this type of concrete, instead of cement, various materials such as micro silica, metakaolin, zeolite, etc., and chemical solutions are used to complete the geopolymerization process to form the binding adhesive substance. The present study examines the durability of geopolymeric mortars based on blast furnace slag (GGBFS) with different replacement percentages of kaolin in several molar amounts. The GGBFS was used as a substitute for cement, and sodium hydroxide solution with a concentration of 4 and 8 M and sodium silicate (glass water) were used as chemical solutions. For this purpose, kaolin ceramic powder was mixed with GGBFS at 50% and 75%, and a total of 12 mixing plans were made. Compressive strength, rapid chloride migration test (RCMT), electrical resistance, water absorption percentage, loss of compressive strength, and weight after exposure to sulfuric acid solution were studied. The results of kaolin powder and slag reduced the compressive strength, and the lowest value of 33% was observed in BSC50-4; Also, the results of the penetration of chlorine ions in concrete and the weight loss of mortar samples in sulfuric acid solution indicate that the use of kaolin powder and slag increases the durability of BSC50-8 concrete samples by 38% under the conditions of chloride attack caused by Permeability decreases.
