Abstract EN
In order to improve the durability of fly ash concrete, a series of experimental studies are carried out, where durability improving admixture is used to reduce drying shrinkage and improve freezing-thawing resistance.
The effects of durability improving admixture, air content, water-binder ratio, and fly ash replacement ratio on the performance of fly ash concrete are discussed in this paper.
The results show that by using durability improving admixture in nonair-entraining fly ash concrete, the compressive strength of fly ash concrete can be improved by 10%–20%, and the drying shrinkage is reduced by 60%.
Carbonation resistance of concrete is roughly proportional to water-cement ratio regardless of water-binder ratio and fly ash replacement ratio.
For the specimens cured in air for 2 weeks, the freezing-thawing resistance is improved.
In addition, by making use of durability improving admixture, it is easier to control the air content and make fly ash concrete into nonair-entraining one.
The quality of fly ash concrete is thereby optimized.
