EXPERIMENTAL WORKS The samples used in this study came from two fly ash produced at the coke combustion of bituminous coals during the petroleum refining of petroleum by the Great Canada Oil Sands Factory (GCOS). The first sample was delivered in 1968 and weighed about 150 pounds. The second sample was taken in 1971 and weighed about 2000 pounds. The chemical analysis of the two samples is shown in Table 1.
