When cement is frozen it shrinks. the salt adds heat and it expands. The cement is not used to the change and it expands to much and it cracks. just like when paper rips.
===============================
I have a different mechanism to propose:
-- Salt on the surface of the frozen rock melts the fine layer of ice on the rock,
just as it does when salt is used on the roads or sidewalks.
-- The liquid water seeps into microscopic cracks in the cement.
-- When the water re-freezes, it expands, cracking the cement.
It will be saturated salt solution with salt crystals at the bottom of the container.
Salt remain as residue after evaporation.
You put the wrong stuff in your salt shaker.
Yes, magnesium can be used in the production of cement as a mineral additive to improve the properties of the cement mix, such as setting time and strength. However, excessive amounts of magnesium can be detrimental to the quality of the cement.
Put salt and ice in a bucket and then set the coke in the bucket. You can also put ice in the coke
Put luke-warm water on it. Boiling water will crack glass.
Ice has a freezing point which is generally 32 degrees and when salt is put onto frozen water it turns it into liquid. When it turns into liquid it's no longer frozen as long as the salt remains present.
you should put water on it for an year and keep it in a cool region ;you can do it by keeping an umbrella on that crack and just keep watering

To ensure it complies with the specifications for the type of cement and the use to which it is put.

ppc cement
the glass get frozen if you put it to the refrigerator
Crack eggs into the skillet and put them with spacing, so they will don't touch. Then sprinkle with salt and pepper over it. The most standard egg recipe it is!
you put cement down then bricks then cement then bricks. etc.
You probably can't. There is probably a crack in the floor in the space of the door opening. One side will move more than the other, either up and down or sidewise and there is really no way of holding them. If I wanted to try something, if you can get to the outside of the slab under the door you could put a piece of plate steel across the face of the cement and put at least 3 anchors into the cement through the steel on each side of the crack. This might hold the two sides in place, but there's no guarantee this will work or that the slab will not split or crumble when you drill it.
no not if it is put together
