Usually, flowable fill mix designs are proportioned based on the percentage of fly ash, on a dry weight basis. The high fly ash content mixes normally contain 95 percent fly ash and 5 percent portland cement. In some areas, self-cementing fly ash accounts for 100 percent of the cementitious material. Because the low fly ash content mixes contain an additional ingredient (sand or filler), there is a …
