Changes in the salt attack resistance of concrete using ground granulated blast furnace slag (GGBFS) were examined based on different curing conditions. These conditions were divided into air and underwater curing. Three concrete mixes with GGBFS replacement ratios of 0 (control group) 30 and 60 were fabricated. Then evaluation of concrete compressive strength evaluation of chloride ion

Quality Evaluation of Granulated Blast Furnace Slag Sand

Blast Furnace Slag Quality Evaluation Resistance Test Acid Freeze- Thaw. 1 Introduction . Granulated blast furnace slag (GBFS) is produced by injecting pressurized water to rapidly cool the molten slag produced in the blast furnace. This product is popular in Japan and other countries for use as raw material for cement.

Slag handling is an important aspect of modern blast furnace operation. Today blast furnace slag is a saleable product (granulated slag sand used as CO 2-friendly substitute of clinker in cement production) rather than a difficult and costly waste material.Paul Wurth has developed the INBA ® slag granulation process incorporating our proprietary dynamic INBA dewatering drum.

Processing of Granulated Blast Furnace Slag and its

After the granulated blast furnace slag is formed it must be dewatered dried and ground using processes similar to those used with Portland cement clinker to make Portland cement. Typically granulated slag is ground to an air-permeability (blaine) fineness exceeding that of Portland cement to obtain increased hydraulic activity at early ages.
