Abstract
Yuqori markali sement olishda faol mineral komponentlarning reaksion imkoniyatini polikarboksilat superplastifikatorlarning disperslovchi ta’siri bilan uyg‘unlashtirish tarkib va texnologiyani birgalikda optimallashtirishni talab qiladi. Mazkur maqola loyihasining maqsadi polikarboksilat efiri (PCE), mikrokremnezem (MKr) va metakaolin (MK) asosidagi organo-mineral qo‘shimchalarning tarkibini tanlash hamda ularni sementga kiritish texnologiyasini ilmiy asoslashdan iborat. PCE-SF, PCE MK va PCE-SF-MK tizimlarini qo‘shimchasiz, faqat PCE hamda faqat mineral komponentlar saqlovchi tarkiblar bilan qiyoslash taklif etiladi. Tadqiqot dasturi xomashyoni rentgen-fluoressent va rentgen-diffraksion tahlil qilish, zarrachalar dispersligini aniqlash, polimer sarflanishini umumiy organik uglerod usulida baholash, reologik o‘lchovlar, izotermik kalorimetriya, termogravimetriya va mustahkamlik sinovlarini birlashtiradi.
