Why does cement crack after salt is put on it when it is frozen?
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.
