For M20 grade, 25% is the optimum percentage of stone dust mix with the concrete. 30% of stone dust requires relative high cement content. If 50% replacement of sand 450 kg per meter cube cement needed to achieve the target means strength for M25 grade. Also, the increase in water-cement ratio didn't yield a positive result.
However, the comparison of configurations F, G and H shows that at high fines content (i.e., 12%) the response is different. A sample with lower dust ratio (i.e., F) shows a Range C type material behavior and a sample with higher dust ratio (i.e., H) results in Range A. Configuration G with DR of 0.6 shows a behavior in between these two limits.

The utilization of waste fly ash in road construction is primarily confined to its use in embankment filling or as a stabilizer when combined with lime and cement. Its application in structural pavement layers, such as the base and subbase, faces a challenge due to the high volume of fine particles, which renders it brittle when stabilized. In this study, fly ash was …
