QAYTA ISHLANGAN BETON CHIQINDILARIDAN FOYDALANIB EKOLOGIK TOZA BETON ISHLAB CHIQARISH: FIZIK-MEXANIK XUSUSIYATLARINI TADQIQ ETISH
Abstract
Qurilish va buzish chiqindilari hajmining ortib borishi qurilish materiallarini ishlab chiqarishda resurslarni tejovchi va ekologik barqaror texnologiyalarni qo‘llash zaruratini kuchaytirmoqda. Mazkur tadqiqotda qayta ishlangan beton agregatini (RCA) tabiiy yirik agregatning qisman yoki to‘liq muqobili sifatida qo‘llashga asoslangan hisobiy yondashuv taklif etiladi. Tadqiqot doirasida tabiiy yirik agregatni 0, 25, 50, 75 va 100 foiz miqdorida RCA bilan almashtirish variantlari ko‘rib chiqiladi. Betonning zichligi, suv shimuvchanligi va siqilishdagi mustahkamligiga RCA ulushining ta’siri ilmiy adabiyotlarda keltirilgan qonuniyatlar va material xususiyatlari asosida baholanadi. Taklif etilgan yondashuv RCA ning maqbul ulushini aniqlash, tabiiy agregat sarfini kamaytirish va qurilish chiqindilaridan samarali foydalanish uchun ilmiy asos yaratadi.
