Statistical modelling of carbonation coefficient in concrete

Abstract

Current models for the carbonation coefficient in concrete cannot comprehensively consider the impact of water-to-binder ratio, replacement of mineral admixtures, and the coupling effect of each other. To overcome this limitation, an improved model for carbonation coefficient was developed based on 96 sets of concrete carbonation test data under standard carbonization environment. Compared with the reference models, the proposed model has a higher precision.
