Sulfatbardosh portlandsement

Standart: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.
