Guideline for service life design of structural concrete: A performance based approach with regard to chloride induced corrosion

Nowadays major structures require a service life of 100 years or even more. CUR committee VC81 has developed a guideline for service life design based on initiation of corrosion due to chloride penetration for exposure classes XD or XS. A semi-probabilistic simplification of the DuraCrete methodology is introduced with a probability of failure...

Critical chloride concentrations in reinforced concrete specimens with ordinary Portland and blast furnace slag cement

Chloride induced reinforcement corrosion is the predominant degradation mechanism affecting reinforced concrete structures. Chlorides (Cl^-) contained in sea water or de-icing salts penetrate through concrete pores by diffusion and/or convection. Reinforcement corrosion initiates when the Cl concentration at the reinforcing steel...

Modified hydrotalcites as chloride scavengers and inhibitor release agents for improved corrosion protection of reinforced concrete

Owing to the unique molecular structure and high ion exchange capacity, hydrotalcites are believed to have a potential to be modified and tailor-made as an active corrosion protective component of reinforced concrete. In this paper, two types of modified hydrotalcites (MHT-pAB and MHT-NO2) were tested both in alkaline solution and mortar for...
