چکیده

سالانه میلیون ها تن را به دنبال دارند. در این تحقیق ضایعات درشت و پودر پساب کارخانجات سنگبری با رزین ترکیب و اسلب های سنگ مصنوعی تولید شده است. نتایج نشان می دهد اسلب های تولیدی دارای مشخصات فیزیکی و شیمیایی مطابق با استانداردهای ملی ایران برای سنگ ساختمانی می باشند. با افزایش مقدار رزین در ترکیب سنگ، مقاومت خمشی و کششی افزایش و مقاومت فشاری و ضریب جذب آب کاهش یافته است. اسلب های تولیدی از ضایعات سنگ گرانیت در مقایسه با اسلب های تولیدی از ضایعات سنگ مرمریت دارای مشخصات فیزیکی و مکانیکی بهتری هستند. در بهترین شرایط، با هدف بیشترین مصرف ضایعات، با ترکیبی شامل 90درصد ضایعات مرمریت و 10درصد رزین، اسلب های تولید شده است که دارای مقاومت فشاری 143مگاپاسکال، مقاومت خمشی 21مگاپاسکال، مقاومت کششی 25مگاپاسکال، ضریب جذب آب 1درصد و وزن مخصوص 32/2می باشند.

چکیده [English]

Million tons of waste are produced annually in mining and processing of dimension stone in Iran. In most cases, the waste is released in nature that would cause environmental hazards. In this work, artificial stone slabs were manufactured by combination of coarse waste and sludge powder of stone cutting factories. The results show that the manufactured stone slabs have physical and mechanical specifications according to Iranian national standards for building stone. With increasing the amount of resin in the composition, the flexural and tensile strength were increased and the compressive strength and water absorption coefficient were decreased. The slabs produced from granite waste compare to the slabs produced from marble waste had better physical and mechanical specifications. At the optimum condition, with the aim of using more waste, with a composition of 90% marble waste and 10% resin, artificial stone slabs were produced which have compressive strength about 143 MPa, flexural strength of 21 MPa, tensile strength of 25 MPa, water absorption coefficient 1% and density equal to 2.32 g/cm3.
