Talk:Silica fume

From Wikipedia, the free encyclopedia

This entry was taken in whole from http://www.fhwa.dot.gov, a federal agency.

The conversion of 215,280 sq ft./lb to 20,000 sq meter/kg isn't right. 215,280 sq ft/lb = 20,000 sq. meter/lb. In sq meters/kg it's 44,000. I didn't edit the pages as I'm not sure which is right. Regardless, the conversion is wrong. I found the reference at http://www.fhwa.dot.gov and it contains these same numbers but one of them is certainly wrong. —Preceding unsigned comment added by 63.122.213.254 (talk) 16:21, 14 May 2008 (UTC)

I contacted fhwa.dot.gov and they are correcting the page that this information was taken from to read, "Silica Fume consists of very fine vitreous particles with a surface area ranging from 60,000 to 150,000 ft^2/lb or 13,000 to 30,000 m^2/kg." I'll edit the article to reflect this. Scot —Preceding unsigned comment added by 63.122.213.254 (talk) 17:45, 16 May 2008 (UTC)
