CHLORIDE EXTRACTION FROM REINFORCING STEEL IN CONCRETE

Chloride Extraction from Reinforcing Steel Chloride extraction is another method of preventing future corrosion of steel. Electrochemical chloride extraction (ECE) is a treatment process where chloride ions are removed from chloride-contaminated concrete through ion migration. Unlike a cathodic protection system, there ...

COARSE AGGREGATES IN HIGH STRENGTH CONCRETE

COARSE AGGREGATES IN HIGH STRENGTH CONCRETE Given the critical role that the interfacial transition plays in high-strength concrete, the mechanical properties of coarse aggregate will have a more pronounced effect than they would in conventional-strength concrete. Important parameters of coarse aggregate ...

PROPORTIONING OF HIGH STRENGTH CONCRETE

When developing mixture proportioning for high-strength concrete, three fundamental factors must be considered in order to produce a mix design satisfying its intended property requirements:Mechanical properties of the aggregates, Mechanical properties of the paste, Bond strength at the paste-aggregate interfacial ...
