The model was found to be highly significant ( p < 0.001), confirming a strong correlation between the input variables (cement, Ferrock, and OA) and the compressive strength response.

Results and discussion Workability Figure 4 shows a clear trend of decreasing workability as the percentage of Ferrock increases from 0% to 50% in the concrete mix.
