Durability of Low Carbon Concrete Mixtures

The primary goal of this proposal is to develop a deeper understanding of the relative performance of a wide array of low-carbon concrete systems in environments where the concrete will be subjected to chlorides and other deicing salts. This goal will be met through the following objectives: (1) understand the chloride diffusion rate in low-carbon concrete mixtures; (2) understand the relative resistance of various low-carbon concrete mixtures to salt scaling; and (3) develop life-cycle expectancy models for various low-carbon concrete mixtures. The intended outcome of the project is to present a systematic approach to examining the durability of a wide array of low-carbon concrete mixtures. The information gathered will be used to predict life expectancy of the concrete in regards to onset of corrosion and likelihood of significant scaling.
