a bag of cement is open it gets wet.Next day the sun shines brightly can this be a reversible change?

Answer 1

no once it's wet it hardens and thats that!

Answer 2

The cement shall set into a hard mass. This setting is due to the hydration of the componants of cement such as Dicalcium silicate, tricalcium silicate, tricalium aluminate and tetracalcium alumino ferrite. To reverse this change you need to reheat the hydrated cement in a kiln at very high temperatures.

Answer 3

I used to sell bagged concrete and we always had to keep it from getting damp. Usually what would happen when it got wet was that it wouldn't set up completely hard like mixed concrete but clump up in little clumps making it useless. We always had to throw those bags out, so I am guessing once it goes through that process it can't be reversed. If it conpletely sets up it obviously cant be reversed.

Answer 4

irreversable
use the cement imediatly or remove the part that got wet
in 2 days it becomes unusable
happens to me all the time

once the cement gets wet
the reaction is reacting and drying in the sun only makes it unusable faster

better to keep it in the shade untill you are ready to use it and you only got hours to make up your mind
not days

Answer 5

No, the reaction between water and cement is can not be reversed, i.e., you cannot get back cement, by drying the wt cement.

Answer 6

Nope

Answer 7

cement compounds dry and cannot reverse

Answer 8

A Big NO......... It is not a reversible Process.

Answer 9

don't put it under the sun shine. it may be useless.please give it to someone who need it.

Answer 10

nope
