Abstract
Polikarboksilat superplastifikatorlari asosan HPEG va akril kislotasi asosida superplastifikator sintez qilindi. Polikarboksilatning qo’shimcha qo’shilgan beton namunalarining mustaxkamlik natijalari taxlil qilindi. Natijalar shuni ko’rsatdiki, polikarboksilat superplastifikatorining sintez qilib kerakli natijaga erishildi. Boshqa turdagi plastifikator qo’shimasi bilan taqqoslandi. Olingan mahsulotni beton qorishmasiga qo’shib oquvchanligi va mustaxkamligi yaxshilanishiga erishdik.References
