Sulfatbardosh portlandsement


ССПЦ 400-Д0 GOST 22266-94, GOST 30515-97

Ishlab chiqarish jarayoni:

  • Xom ashyo kukunini tayyorlash;
  • Xom ashyo kukunini kuydirish va klinker olish;
  • Klinkern gips bilan tuyib va sulfatbardosh portlandsement olish;

Qo'llanilishi:

Sulfatbardosh portlandsement tarkibida sul’fat mavjud bo’lgan muxit ta’sirida yemirilishga chidamli xususiyatga ega beton va temirbeton qurilmalarni ishlab chirarishga mo’ljallangan.
