The Effect of Fly Ash on Water Transport of Concrete in Dry State

Abstract:

Article Preview

Water transport is an important parameter that affects the long term performance and degradation of concrete greatly. Nowadays, adding fly ash is a promising solution to achieve high-performance, low-price and environment-friendly concrete. To characterize the effect of fly ash on water transport of concrete, especially in dry state, moisture variations and microstructure of concrete with different mix proportions were studied in this paper. Test results reveal that fly ash will increase the porosity of early curing concrete, the higher porosity leads to a faster evaporation, which accelerates the transport of water in cement based materials.
