HCl will dissolve concrete, and concrete workers such as plasterers clean their wheelbarrows and tools with a dilute solution. The HCl attacks the CO2 molecules.

What happens when you mix water with cement?
Cement reacts with water (this reaction is known as hydration).
What is the reaction of cement with hydrochloric acid?
a big fizz
Is mixing cement and water reversible?
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.
Why strong acid is hydrochloricacid?
Hcl is strong acid because it is easily loose H+ ions
Which acid is stronger between sulphuric and hydrochloricacid?
Sulfuric is stronger than hydrocloric.But HCl also a strong acid.

Is making cement a chemical reaction?
yes

Is cement recyclable?
No, cement is not recyclable.Because when it is mixed with water chemical reaction takes place and gains strength and hardens.The hardened cement cannot be used as a recycled one because no chemical reaction takes place when mixed with water.
Why is a chemical reaction in cement so important to concrete?
to make it strong
Why is there a foul smell coming from the patch you used contact cement on?
If it's a different foul smell than the contact cement itself, you've got a reaction between the cement (or more precisely, the solvent in the cement) and the item you put it on.

Hcl is strong acid because it is easily loose H+ ions
Which acid is stronger between sulphuric and hydrochloricacid?
Sulfuric is stronger than hydrocloric.But HCl also a strong acid.
What is the importance of setting time of cement?
because when we know the setting time of cement we easily identified that where can we use the cement according to there setting time.
How can you turn limestone to cement?
Powdered limestone has to be heated with powdered clay to turn it into to cement. You can then use cement and powder it, then mix with water, sand crushed rock and a slow reaction takes place forming concrete. It is in the Cors Science GCSE
When cement is allowed to set why does it give off heat?
The hydration of cement is an exothermic reaction. Three exothermic reactions are important: - hydration of gypsum and tricalciumaluminate - hydration of dicalciumsilicate - hydration of tricalciumsilicate
