چکیده | ||
بتنهای اصلاحشده پلیمری کامپوزیتهای جدیدی هستند که به دلیل عملکرد نسبی بالا چند قابلیتی و پایداری در مقایسه با بتن سیمان معمولی بهعنوان یکی از مواد محبوب در صنعت ساختوساز مورداستفاده قرار میگیرند در این بتنها با افزودن پلیمر میتوان برخی از ضعفهای 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 سنگدانههای لیکا اندازهگیری شد. در این راستا 15 طرح اختلاط مختلف در دو برنامه آزمایشگاهی انجام شد بدینصورت که در مرحله اول تأثیر هریک از لاتکسها با درصدهای 5، 5/7 و 10 درصد باسیمان موردبررسی قرار گرفت و در مرحله بعد تأثیر همزمان لاتکس با میکروسیلیس بر خواص بتن سبک اندازهگیری شد. نتایج نشان داد که افزودن لاتکس تأثیر چشمگیری بر مقاومت فشاری و خمشی بتن داشته است. در بین لاتکسهای استفادهشده، اتیلن وینیل استات تأثیر 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 concretes 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 light expanded clay aggregates were measured. In this regard, 15 different mixing schemes were performed in two laboratory programs. At the first stage, the effect of each latex with 5, 7.5 and 10 percent combined with cement was investigated, and in the next stage, the simultaneous effect of latex with Silica fume. 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. | ||
