The carbonation is one of the main causes of corrosion of reinforced concrete. It is a chemical reaction where carbon dioxide (CO₂) from the atmosphere enters the pores of the concrete and reacts with calcium hydroxide, reducing its pH (from 12.5-13.5 to values below 9). This drop in alkalinity destroys the protective layer of the steel, leading to oxidation (rust).
By investing in concrete with high resistance to carbonation, you ensure that the "skeleton" of your home will remain healthy, safe and unchanging over time.
Exhibition Categories:
-
- C20/25 XC1: It is applied to columns, beams and slabs inside houses. Foundations in non-aggressive soils without humidity changes.
- C25-30 XC2: It is mainly applied to the load-bearing structure of buildings (columns, beams, slabs) and to foundations or basement walls that are in constant contact with moisture or wet soil.
- C25/30 XC3: It is applied to exterior elements protected from rain (e.g. under sheds, balconies) or in interior spaces with moderate to high humidity, such as bathrooms and kitchens.
- C30/37 XC4: It is applied to exterior surfaces directly exposed to rain, such as facades, balconies and exterior walls, as well as to load-bearing elements of high demands (columns, slabs) of large structures.
