High-volume fly ash concrete applying in foundation construction for blower fan

Fly ash is one of the waste of metal lurgicallurical and electric industry.The high-volume fly ash,as a concrete admixture,can be compounded into concrete.The high-volume fly ash concrete has many merits.For example,it has small water requirement,small ignition loss and high compression strength.The high-volume fly ash can improve the mechanical and frost resisting property of the concrete and the impermeability.The high-volume fly ash concrete design and the quality control in production process by analyzing the situation of experiment and application in foundation project are discussed.The reason of problem which is discovered in construction process is analized.
