METHOD FOR PRODUCING SOLIDIFIED SLAG, SOLIDIFIED SLAG, METHOD FOR PRODUCING COARSE AGGREGATE FOR CONCRETE, AND COARSE AGGREGATE FOR CONCRETE |
摘要 |
<p>Provided are a method for producing solidified slag capable of serving as a raw material for a good-quality coarse aggregate for concrete, solidified slag produced by the method for producing solidified slag, a method for producing coarse aggregate for concrete using the solidified slag, and a coarse aggregate for concrete produced by the method for producing coarse aggregate for concrete. This method for producing solidified slag comprises a slag solidification step wherein blast furnace slag (3) in a molten state is poured into a moving metal template (5) and cooled so as to solidify in a plate-shape inside the template, a slag dropping step wherein the slag solidified to the interior while inside the template is dropped from the template by inverting the template, and a slag temperature holding step wherein the surface temperature is held at 900°C or higher for 5 minutes or longer for a portion of the slag surfaces or all the surfaces of the dropped slag.</p> |
