This document specifies a method of determining the carbonation rate of a concrete, expressed in mm/√a. This document establishes a procedure where a standardized climate controlled chamber is used and where specimens are placed on a natural exposure site protected from direct rainfall. The standardized climate controlled chamber procedure is the reference method. These procedures are applicable for the initial testing of concrete, including those manufactured with slowly reacting binders, provided that the ages at which the carbonation depth is measured, the number of measurements required to calculate the carbonation rate, as well as the length of exposure to CO2, are appropriately selected, as described in this document. These procedures are not applicable for factory production control.Ryšiai
