چکیده
بتن‌ یکی‌ از مصالحی‌ است‌ که‌ در ساخت‌ و سازها بیشترین‌ استفاده را دارد و دلیل‌ آن سختی‌ ، دوام و مقاومت‌ زیاد آن است‌ . منافذ معمولا با سیالِ پر می‌شوند. تا کنون نانوساختارهایی‌ با شکل های منظم‌ و بی‌ نظم‌ از مواد مختلف‌ ساخته‌ شده اند که‌ در مجموع یکی‌ از متنوع ترین‌ دسته‌ مواد را تشکیل‌ می‌ دهند. در این‌ راستا ٣٠ نمونه‌ برای انجام آزمایش‌ مقاومت‌ فشاری، ٣٠ نمونه‌ برای انجام آزمایش‌ کششی‌ ساخته‌ شده و مورد آزمایش‌ قرار گرفته‌ است‌. میزان نانوسیلیس‌ و نانورس در سه‌ نسبت مختلف‌ 0.25 و 0.50 و 0.75 وزن سیمان به‌ مخلوط بتن‌ اضافه‌ شده است‌. نتایج‌ بدست‌ آمده نشان دهنده افزایش‌ مقاومت‌ فشاری، کششی‌ بتن‌ در اثر افزودن نانوسیلیس‌ و نانورس است‌

چکیده English

Concrete is one of the most widely used materials in construction, and the reason for that is its hardness, durability and high resistance. Pores are usually filled with fluid. So far, nanostructures with regular and irregular shapes have been made from different materials, which in total form one of the most diverse categories of materials. In this regard, 30 samples were made and tested for compressive strength testing and 30 samples for tensile testing. The amount of nanosilica and nanoclay in three different ratios of 0.25, 0.50, and 0.75 of cement weight has been added to the concrete mixture. The obtained results show an increase in the compressive and tensile strength of concrete due to the addition of nanosilica and nanoclay
