Apr 10, 2013· Blast furnace slag is mildly alkaline and exhibits a pH in solution in the range of 8 to 10. Although blast furnace slag contains a small component of elemental sulfur (1 % to 2 %), the leachate tends to be slightly alkaline and does not present a corrosion risk to steels in pilings or to the reinforcement steels embedded in concrete structures made with blast furnace slag cement or .
First of all Holy F***! You are sitting on a pile whose potential worth in India is at least Rs. 300 crore (50 million)!! I am not sure what you are seeking here on Quora, when the answer should be obvious to someone in possession of such a hu...
From a materials requirements perspective, a blast furnace refractory lining may be split into five areas from top to bottom. Upper shaft: In this low temperature area, abrasion by the solid burden is the primary mode of wear. Our SiC 85P, a silicate bonded SiC, has proven to be a costeffective solution.
Portland Slag Cement (PSC) is manufactured by either intergrinding in the Portland cement clinker, Gypsum Granulated Slag or mixing the Ground Granulated Blast Furnace Slag (GGBS) with Ordinary Portland Cement by means of mechanical blenders. It is created with a blend of 45 50% slag, 45% 50% clinker, and 35% gypsum.
