Supersonic processing FA's activation studied by orthogonal method

Orthogonal methods are used to supersonic processing's effects on FA's activation.By taking cement paste 3-day strength,28-day strength as indexes,the effect of a series factors(supersonic processing's time,supersonic processing's strength,the mount of supersonic processing's FA) and different proportional levels to the indexes are analyzed.Utilized the analytical method of variance,the order of the series factors which influenced the activation of fly ash is made certain,so favorable methods are found to use supersonic processing's FA.
