DON’T WORRY, BE HAPPY
In spite of the somewhat uncooperative temperatures, the curing of the south wall concrete is complete. For the first two days the chemical reactions of the curing process are exothermic --- they generate and give off heat --- and this is sufficient to prevent freezing. After that time the heat generation stops but the concrete is still dewatering. What we didn’t want to happen was that the moisture generated by the continuing dewatering froze as an icy crust on the surface of the concrete. That would result in concrete that would start to spall off pieces somewhere down the line.
The propane heating units kept the temperature up around 60oF beneath the tarps for all six days until the curing was complete. So the tarps are now coming off and being packed up.
With the wall completed the next step will be to level the ground within the building.
So at ease folks and smoke 'em if you've got 'em.
