MIXING RATIO OF FLY ASH CONCRETE
In this report the so-called DOE method for concrete production has been developed to include the processing of a concrete containing fly ash. Experimental results are reported showing that the two fundamental relationships between mix production and concrete properties as expressed in 1) Lyse law and 2) Bolomey law, can be expanded to include fly ash concrete. Lyses law may now be expressed as: For given materials the workability of concrete mixes is a function of the free water content and the fly ash content. Bolomey law may now be expressed as: For given materials curing conditions and curing time the concrete strength is a function of the free water/cement- and water/fly ash ratio exclusively and is independent of the absolute water content, cement and fly ash content. Limits of the modified Lyse law and formulas for the modified Bolomey law are presented in the report.
