oa Civil Engineering = Siviele Ingenieurswese - Aspects of steel corrosion in concrete



The extent to which chloride contained in concrete can be bound by two South African cements has been measured. Estimates of the residual concentration of chloride in the pore solution in concrete are presented. The residual chloride concentrations are compared with published threshold concentrations for the corrosion of reinforcing steel. A maximum tolerable limit for the concentration of chloride in the mixing water of concrete is proposed. Methods of minimizing the risk of corrosion are considered.
