Can you get metals hot enough to vaporise? As in if you can get them hot enough can you get iron/aluminium gas, for exampleIf it can't happen on earth, where? Nebulae? Supernova?
if its too cold the heat of drying in the concrete will be more intense and may cause it to crack as the heat is disipated non uniformlyI would guess the ideal temperature would be 60-75 FIm sure it would say on the side of a consumer bag.
Absolutely! At STP, Aluminum melts at 660.37 °C, and boils at 2467 °C, while Iron melts at 1535 °C, and boils at 2750 °CAnd we can achieve those temperatures right here on EarthMost metals are more useful in solid or liquid form, but that doesn't mean they can't boilAluminum vapors, in particular, are usefulEvaporated under vacuum (so the boiling point is not as high), they are used to form coatings that are highly reflective of visibile and infra-red light, and are useful for the rear coatings of telescope mirrors, decorative papers, toys, and packaging, among other things.
According to guidelines established by ACI Committee 306 (Cold Weather Concreting), for ambient air temperatures between 0 to 32 degrees F, concrete should maintain the following temperatures during curing: 65 degrees F for thin sections 60 for moderate size sections 55 for mass concrete This can be accomplished by using an insulation blanket, batt insulation, or even by using dry strawThe insulation blanket will help keep the heat produced by the hydration reaction in the concreteThis will be enough to keep the concrete sufficiently warm In short, if the ambient temp is below freezing, you should definitely use blankets or some other type of insulation (use isn't optional)If you don't use blankets, you risk having the concrete freeze during the curing period, which will cause the concrete to stop developing strength.
