WebIt is shown that a given strength can be achieved with conditioned PFA concrete with some reduction in w/c ratio, compared to equivalent dry PFA mixes. The adjustment required is progressive with conditioned PFA storage period (up to 6 months), but is not influenced significantly by either dry PFA characteristics or conditioning/storage variables.
