| چکیده | ||
| بتن های اصلاح شده پلیمری کامپوزیت های جدیدی هستند که به دلیل عملکرد نسبی بالا چندقابلیتی و پایداری درمقایسه با بتن سیمان معمولی به عنوان یکی ازموادمحبوب درصنعت ساخت و ساز مورداستفاده قرارمی گیرند دراین بتن ها با افزودن پلیمر میتوان برخی ازضعف های بتن معمولی را اصلاح کرد. در این پژوهش با افزودن سه لاتکس مختلف شامل استایرن بوتادین رابر، اتیلن وینیل استات و اکریلیک لاتکس خواص مکانیکی و دوامی بتن سبک شده با سنگدانه های لیکا اندازه گیری شد. در این راستا 15 طرح ختلاط مختلف در دو برنامه آزمایشگاهی انجام شد بدین صورت که در مرحله اول تاثیر هریک از لاتکس ها با درصد های 5، 5/7 و 10 درصد با سیمان مورد بررسی قرار گرفت و در مرحله بعد تاثیر همزمان لاتکس با میکروسیلیس بر خواص بتن سبک اندازه گیری شد. نتایج نشان داد که افزودن لاتکس تاثیر چشمگیری بر مقاومت فشاری و خمشی بتن داشته است. در بین لاتکس های استفاده شده، اتیلن وینیل استات تاثیر بهتری را نشان داده است | ||

| چکیده [English] | ||
| Reinforced polymer concretes are new composites that are used as one of the most popular materials in the construction industry due to their high relative performance, versatility and stability compared to ordinary cement concrete. In these concretes, some weaknesses of ordinary concrete can be corrected by adding polymer. In this study, by adding three different latexes including styrene butadiene rubber, ethylene vinyl acetate and acrylic latex, the mechanical properties and durability of lightweight concrete with Leica aggregates were measured. In this regard, 15 different mixing designs were performed in two laboratory programs. In the first stage, the effect of each latex with 5, 7.5 and 10% percent with cement was investigated, and in the next stage, the simultaneous effect of latex with microsilica. The properties of lightweight concrete were measured. The results showed that the addition of latex had a significant effect on the compressive and flexural strength of concrete. Among the latexes used, ethylene vinyl acetate has shown a better effect | ||
