The Manufacturing Process Manufacturing Skyway Slag Cement requires two basic processes: granulation and grinding. Blast-furnace slag is produced in a blast furnace during the reduction of iron ore to iron. It consists of non-metallic minerals, which are tapped slag from the blast furnace while molten. By processing blast furnace slag into …

At present, the research on rice hull ash and cement-based materials as cementitious materials continues to deepen. Low-cost rice hull ash replaces part of Portland cement, which plays a dual role in saving material costs and improving environmental benefits. In this study, alkali-activated rice husk ash (RHA) and ground granulated blast …

Granulated blast furnace slag (GBFS) is obtained by rapidly quenching the molten slag by using high-pressure water jets. It is glassy granular particles having generally smaller than 5 mm particle size like sand. The GBFS is often used after further processed by drying and then grinding to a very fine powder. GBFS can be used as a …

Ground granulated blast furnace slag also has a lower heat of hydration and, hence, generates less heat during concrete production and curing. GGBFS is a desirable material to utilize in mass concrete placements where control of temperatures is an issue. GGBFS can be used instead of cement with the ratios from 10 to 90%.
