Abstract
A heavy oil ash self-compacting concrete can include aggregate, heavy oil ash fines, water, and cement. The heavy oil ash can include more than 90% carbon, by weight. In an embodiment, the heavy oil ash self-compacting concrete can flow under its own weight and yet maintain a stable mixture consistency.
