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.
Cement reacts with water (this reaction is known as hydration).
a big fizz
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.
Hcl is strong acid because it is easily loose H+ ions
Sulfuric is stronger than hydrocloric.But HCl also a strong acid.

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.
to make it strong
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.

because when we know the setting time of cement we easily identified that where can we use the cement according to there setting time.
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
The hydration of cement is an exothermic reaction. Three exothermic reactions are important: - hydration of gypsum and tricalciumaluminate - hydration of dicalciumsilicate - hydration of tricalciumsilicate
