Abstract
A concrete mixture that includes aggregates, water and cement can include heavy oil ash instead of or in addition to a portion of the cement. In one embodiment, the heavy oil ash originates from heavy fuel oil burned in a power generation plant. The weight of the heavy oil ash used in the concrete mixture can be from greater than 0 to about 10% of the weight of the cement.
