Concrete Repair andProtection SystemHow Durable is Concrete?Reinforced concrete, the mostsignificant construction material ofour time, for many years wasconsidered to be resistant toenvironmental effects. Reinforcedconcrete manufactured tospecification is durable andalmost indestructible.Its high alkalinity (pH ≈ 13) protectsreinforcing steel from corrosion.However, defects in manufacture,inadequate steel cover and externalinfluences can cause severe damage.Carbonation –a Critical FactorNatural ingress of carbon dioxideconverts the calcium hydroxidecontained in concrete to calciumcarbonate, thereby reducing the highalkalinity and anticorrosionproperties. With low steel cover ofpoor concrete quality carbonationcan cause the steel to corrode asoxygen and water combine to producerust and spalling.Main Causes of ConcreteDamageEnvironmental influences andconstruction defects are the majorcauses of concrete damage:■ carbonation due to CO 2■ de-icing salts■ insufficient steel cover■ poor concrete qualityThe extent of damage and appearanceare governed by the cause andprogress of the concrete deterioration.SystematicConcrete RepairOnly a systematic procedure willresult in a durable concrete repair.Equally important is a high-quality,tested product system with balancedcomponents.The Vandex CRS program providesproducts and know-how for assuredsuccess in concrete repair.Concrete Repair MeasuresFollowing a Clear ConceptStructural examinationCarbonation depth as afunction of age structureand concrete qualitycarbonation depth [mm]302010 N/mm 225 N/mm 2Damage diagnosis/Damage classificationRepair conceptRepair of structureQuality assurance andInspection programAssessing the compressivestrengthMeasuring depth of concretecover with a Covermeter1035 N/mm 245 N/mm 210 20 30age of structure [years]Structural ExaminationAn examination of the structureusing special equipment providesinformation to enable a correctdiagnosis and damage assessment,which leads to an appropriate repairconcept.
