metallic grout
(OP)
Can somebody explain to me why one would use metallic grout? Often times in specs I see "use non-shrink metallic grout". I think I can see why one would not use a metallic grout, due to possible staining issues, but what are the benefits of using a metallic grout.
Thanks
Thanks

IMO, this outweighs any advantage that might be had from using metallic grouts. But like you, I don't really know what those advantages are.

RE: metallic grout
Al+ reacts with calciums and other components of concrete (particularly uncontrolled, as aggregates often introduce additional free chemical components of the reaction). The use of metallic grout is much less of concern than the use of metallic expansive cements, which have been widely discredited, but it seems that the engineering comunity has forgotten the "why" of this dismissal... Sadely I have seen two properties with the 35 year Petrosky effect due to the use of metallic admix.
This has been discussed previously on Eng-tips, and I believe it was Mike M who does not even permit Aluminum tools on site! I completely agree, and similarly stipulate an Aluminum free site.
Hope that's a little more clarity,
Cheers,

Neither of these is popular anymore, particularly with the advent of epoxy grouts and cement-filled epoxy grouts.
Metallic grouts can cause lots of issues, particularly advancing the corrosion of embedded items.
