Portland cement (and the concrete, mortar, thin set, or other masonry product made from it) doesn't dry. Rather, it cures by a chemical reaction initiated by putting water in it. The reaction is irreversible; hence, adding water to cement is an irreversible change.

No, mixing cement and water is not a reversible process. When water is mixed with cement, a chemical reaction occurs that leads to the hardening of the mixture into concrete. This change is not easily reversible without significant effort and resources.

Is mixing cement and water a irreversible change?
Mixing cement and water is a reversible change because the two substances can be separated by allowing the water to evaporate, leaving the solid cement behind. This process does not alter the chemical composition of either the cement or the water.
Why is cement not reversible after mixing with water?
Cement undergoes a chemical reaction called hydration when it is mixed with water, forming a hard and strong material. This reaction creates new compounds that cannot be reversed back into their original state through simple drying or evaporation. Once cement has fully cured, the bond created between the water and cement particles is permanent.
Is mixing alka seltzer and water a reversible or irreversible change?
Mixing Alka-Seltzer and water is a reversible change because it can be undone by allowing the water to evaporate, leaving behind the original substances in their initial forms.
Is mixing oil and water a reversible or irreversible change?
reversible
When mixing to make concrete what do you add to the mix last sand water or cement mix?
Water should be added last when mixing concrete. The general order is to first mix the cement and aggregate (sand), then gradually add water while mixing until the desired consistency is achieved.

Is mixing salt and water a reversible or irreversible?
It is reversible. You can allow the water to evaporate, leaving the salt behind.
Mixing sugar and water is reversible or irreversible?

What effect has the quantity of mixing water have upon the quality of concrete?
the strength of concrete is effected by water /cement ratio as the water/cement ratio increases the strength of the concrete decreases
