An important reason for fly ash cement paste workability and strength is fully mixing, so the needs to be appropriate. Existing in the relevant specification for the mixing time rules are mostly for o mixing time rdinary con- crete, with the development of high performance concrete, especially the wide use of fly ash concrete in recent years, the existing regulations about mixing time cannot satisfy the uniformity of the fly ash concrete requirements. Therefore, this article through the preliminary study of different mixing time on net different dosage of fly ash ce- ment slurry liquid and the...
