Utilization of heavy oil ash to produce self-consolidated concrete

摘要

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.

主权项

1. A heavy oil ash self-compacting concrete, consisting essentially of:
a pozzolanic aggregate; heavy oil ash fines, the heavy oil ash fines comprising at least 90% carbon and at least 80% of the heavy oil ash fines being finer than 45 micrometer (#325 sieve), where the heavy oil ash fines do not have cementitious or pozzolanic properties and do not react with lime; water; and Portland cement; wherein the heavy oil ash cement concrete is produced by the mixing of the water and the Portland cement in the presence of the heavy oil ash fines and aggregate; and wherein the heavy oil ash self-compacting concrete is capable of flowing under its own weight.
