Abstract

Beli supersulfatni cement za izradu belog hidrauličnog vezivnog sredstva za spravljanje konstruktivnih i dekorativnih maltera i betona postojane zapremine, otporan na sulfate i mraz, koji se sastoji od smeše samlevene, granulovane i izbeljene zgure sledećeg hemijskog sastava: kalcijum oksida 54-56 mas.%, magnezijum oksida 5-7 mas.%, silicijum dioksida 24-26 mas.%, aluminijum trioksid 9-11 mas.%, gubitaka žarenjem 7-10 mas.%, mineralnog sastava: belita (2CaO SiO2) 25 mas.%, felita (2CaO SiO2) 55 mas.%, staklaste mase približno 20 mas.%, kojoj je dodato hidratisanog kreča i sirovog gipsa, od čega je predhodno granulovana zgura termički obradjena tako da čine zajednički proizvod, smešu sa druge dve komponente sa gubitkom žarenja manjim od 5 mas.%, samlevenu tako da daje specifičnu površinu smeše po Blenu veću od 2600 cm2/g, stepen beline smeše u odnosu na standardni barijum sulfat je iznad 70%, a zapreminska masa iznad 2,8 g/cm3, naznačen time, što se sastoji od granulovane zgure, na čiju masu se dodaje 6-8 mas% istog sirovog gipsa, 1-4 mas.% hidratisanog kreča i 0,5-0,7 mas.% dolomitnog kreča, pri čemu se dobija smeša čija je finoća mliva manja od 0,07 mm, specifična površina iste po Blenu veća od 450 m2/kg, a stepen beline, u odnosu na standardni barijum sulfat iznad 70% i zapreminska masa bez pora i šupljina veća od 2,8 g/cm3. Prijava sadrži još 1 zavisan patentni zahtev.White supersulfate cement for the production of white hydraulic binder for making structural and decorative mortars and concrete of constant volume, resistant to sulfates and frost, consisting of a mixture of ground, granulated and bleached slag of the following chemical composition: calcium oxide 54-56 wt.%, magnesium oxide 5-7 wt.%, silicon dioxide 24-26 wt.%, aluminum trioxide 9-11 wt.%, annealing losses 7-10 wt.%, mineral composition: belite (2CaO SiO2) 25 wt.%, felite (2CaO SiO2) 55% by weight, glassy mass approximately 20% by weight, to which hydrated lime and crude gypsum have been added, of which the pre-granulated slag is heat treated to form a common product, a mixture of the other two components with an annealing loss of less than 5% by weight, ground to give a specific Blen mixture of more than 2600 cm2 / g, the whiteness of the mixture relative to standard barium sulphate is above 70% and the bulk density is above 2.8 g / cm3, characterized in that consists of granular slag, on whose 6-8% by weight of the same crude gypsum, 1-4% by weight of hydrated lime and 0.5-0.7% by weight of dolomite lime are added to the mass, whereby a mixture is obtained whose fineness of grinding is less than 0.07 mm, specific surface area according to Blen greater than 450 m2 / kg, and the degree of whiteness, in relation to standard barium sulphate above 70% and volume mass without pores and cavities greater than 2.8 g / cm3. The application contains 1 more dependent patent application.
