<p>PURPOSE:To extend the storage period by incorporating at least one kind of a gluconic acid or sodium gluconate for a woter crushed granulated slag. CONSTITUTION:The granulated slag, such as a blast furnace granulated slag, etc., has a self-curing property and most of it is glassy and the smaller the particle size is, the more remarkable tendency of solidification is. Then at least one kind of the gluconic acid or sodium gluconate in the range of 300ppm-1% for the granulated slag is sprayed in a powdery state or in 0.1-3.0% concentration of the aqueous solution or the granulated slag is immersed into the aqueous solution to be adsorbed in the granulated slag particle, thus the solidification of the granulated slag is prevented for a long period.</p> |
