Abstract
The effects of polycarboxylic acid (PC), naphthalene sulfonate (NS), and aliphatic (AH) superplasticizers on the carbonation of concrete were investigated. These three kinds of superplasticizers can improve anti-carbonation performance of concrete, and their order according to magnitude of effect are as follows PC>AH>NS. The mechanism behind this phenomenon was investigated using mercury intrusion porosimetry of the concrete, thermogravimetric analysis, X-ray diffraction, scanning electron microcopy, and X-ray photoelectron spectrometry of synthetic hydrated products. The effects of superplasticizers on carbonation resistance are associated not only with pore structure but also with the morphology of hydrated products.
