Abstract
PURPOSE: To treat blast furnace granulated slag so that it is hardly concreted even after open-air storage for waiting shipment, etc., by sprinkling an aq. soln. of acid over the slag immediately before or after coarse crushing in a granular size regulating process.
CONSTITUTION: Immediately before or after coares crushing for producing slag as substitute sand from blast furnace granulated slag, a more than 10-5 N aq. soln. of acid such as hydrochloric acid or sulfuric acid is sprinkled over the granulated slag. Thus, the slag can be treated so that the concretion preventing power is not lost even if the slag is washed with sprinkled water, rain, etc. at the time of open- air storage.
