چکیده

در این مطالعه، خواص مخلوط‌های دوتایی حاوی سربارۀ فسفر (80 درصد وزنی) و فعال‌کنندۀ مرکب پایۀ سیمان پرتلند (20 درصد وزنی) در سه نرمی بلین 2050، 3030، و cm2/g 4500 مورد بررسی قرار گرفتند. همچنین نرمی بلین cm2/g 3030 به‌منظور بررسی اثر دماهای عمل‌آوری 45، 85 و ºC 200 برروی توسعۀ مقاومت فشاری انتخاب شد. نتایج آزمایش‌ها نشان داد که با افزایش نرمی بلین جرم حجمی توده و زمان گیرش کاهش و نسبت آب به سیمان در قوام معمول و مقاومت فشاری افزایش می‌یابد و در دماهای بالاتر از ºC 45، مقاومت فشاری در انتهای زمان عمل‌آوری کاهش می‌یابد.
