The Importance of Concrete Surface Preparation

The third and final of the ACA and ACRA series of joint webinar presentations on Silicosis and its prevention. Adequate surface preparation is the key to successful concrete repair and concrete protection projects. Inadequate surface preparation often leads to the failure of the repair or coating necessitating further re-work, incurring added expense, facility operational downtime and compromised integrity of the remediation and protection works.

Modelling Durability of Reinforced Concrete Structures

R.E. Melchers Centre for Infrastructure Performance and Reliability,The University of Newcastle, Australia SUMMARY:  Management of reinforced concrete assets increasingly relies on analytical models to predict the time to reinforcement corrosion, particularly to serious, damaging corrosion. Increasingly it is found that predictions by existing models for the onset of chloride-induced reinforcement corrosion do not compare well...

Predicting long-term durability of steel reinforced concrete with calcium nitrite corrosion inhibitor

N. S. Berke1, M. C. Hicks2 1Tourney Consulting Group, Kalamazoo, Michigan, USA 2Grace Construction Products, Cambridge, Massachusetts, USA Summary: Steel reinforced concrete is one of the most durable and cost-effective construction materials, but it can suffer in high chloride environments from corrosion due to chloride-induced breakdown of the normal passive layers protecting the steel. One...
