Mar 01, 2020  The experimental results showed that the compressive strength and fluidity of concrete is worse due to the addition of AEA. When AEA content was 4.6–6.5%, concrete exhibits the best freezing-thawing resistance. Calculation results obtained by damage model agree well with the experimental results of freezing-thawing damage.

The water absorption of two ordinary concretes was determined based on the cold water, boiling water and vacuum saturation techniques. The concretes were produced with water to cement (w/c) ratios of 0.50 and 0.60 and tested at 7 and 28 days. The vacuum saturation was more effective than the cold water and boiling water saturation methods.
