[78] The conversion of calcium hydroxide during the concrete into calcium carbonate from absorption of CO2 above various decades more strengthens the concrete and causes it to be additional resistant to destruction. This carbonation reaction, having said that, lowers the pH with the cement pore Resolution and will corrode the reinforcement bars.
Many of these constructions nonetheless exist right now! The concrete market uses these products, which might normally should be disposed in land-fill websites, to the advantage of concrete. The products take part in the hydration response and appreciably Increase the power, permeability and toughness of concrete.
