Accelerated and natural carbonation of concretes with internal curing and shrinkage/viscosity modifiers por Durán Herrera, Alejandro, Mendoza Rangel, José Manuel, Santos Rodríguez, Edgar Ulises de los, Vázquez, F., Valdez Tamez, Pedro Leobardo, Bentz, Dale P.

“…Conversely, there is less correlation observed between the specimens’ carbonation resistance and their respective 28 days compressive strengths, with the mixtures containing the shrinkage/viscosity modifier specifically exhibiting an anomalous behavior of higher carbonation resistance at lower strength levels. For both the accelerated and natural exposures, the lowest carbonation coefficients are obtained for two mixtures, one containing the shrinkage/viscosity modifier added in the mixing water and the other containing a solution of the same admixture used to pre-wet fine lightweight aggregate. …”
