Study on mechanical property of air-entrained fly ash concrete in freezing-thawing circumstance
Through the rapid freezing and thawing method, In the water after 300cycles of freezing and thawing of fly ash air-entrained agent of concrete were studied, mainly determined the different cycle number of quality loss, relative dynamic elasticmodulus and compressive strength. The experimental results werediscussed and the conclusions can provide the testing andtheoretic basis and the reference for the further research of the concrete structure in freezethaw environment, suggestions of select the airentraining agent content, fly ash contents andwaterbinder ratio of the concrete are introduced.
