Increasing Service-life of Concrete in critical environments

Increasing Service-life of Concrete in critical environments

enerally, the prime concern for concrete for structural engineers has been its resistance to mechanical stress, i.e. strength. In recent years, durability has emerged as equally important.

However, durability cannot be achieved with reducing the W/C ratio, high compressive strength, more cement, air-entraining admixtures or corrosion inhibitors alone.

To achieve concrete durability in critical environments, properties like low permeability, low shrinkage, self-healing and protection against chemical attack must be realized. PENETRON ADMIX incorporates the technology that provides such properties and recent testing has shown it can add up to 60 years or more to a variety of concretes, in critical environments before the onset of corrosion.

Projected Concrete Service Life

These results are in line with ACI report 212.R3-10, which concludes that crystalline admixtures are the best PRAH (permeability reducing admixtures for hydrostatic conditions) and increase durability of concrete.
