Home in the Earth | 9.1 Grouting the Quonset hut steel in place @SimonHomeintheEarth | Uploaded December 2014 | Updated October 2024, 3 hours ago.
Even though it was bolted down, the Quonset hut does not really achieve its design strength until it is grouted in place. With winter coming, I was under pressure to get it done quickly before the temperature dropped and the snow storms rolled in.
It is actually possible to add additives such as plasticizers or accelerators to a concrete mix to accelerate the curing reaction so it will set in colder weather, but, the SteelMaster Quonset installation manual warned that such mixtures may be corrosive. Calcium Chloride, specifically, is known to release steel corroding chloride ions and should never be used with rebar, let alone the thin 20 gage steel of the Quonset hut.
So, on the first warm evening in a while, I headed out there and mixed my own grout from Portland cement and sand found on site..
