Abstract
Ushbu maqolada beton qorishmalarining strukturasini shakllantirishda superplastifikatorlarning alohida roli o’rganiladi. Polikarboksilat superplastifikator (PKE) erituvchisiz polimerlash tizimida sintez qilindi va tez tashish va qulay tayyorlash uchun kukun shakliga aylantirildi. Makromonomer sifatida izopentenilpolietilenglikol (TPEG) dan foydalanib sintez qilingan PSE mos ravishda 60 °C haroratda eng yaxshi oquvchanlik va saqlash xususiyatlarini namoyon qildi. Sintez qilingan superplastifikator qo’shilgan portland sement toshining namunalari ko’rsatilgan. Aniqlanishicha, sintezlangan superplastifikator 0,5-1% miqdorida qo’shilsa, sement qorishmasining tarqalish qobiliyati 1,5 dan 2,5 barobarga, mustahkamligi esa 12% gacha oshgan. Umumiy suv talabi 15-20% gacha kamaydi.References
