Jul 08, 2011· In addition to providing you with calcium, calcium carbonate is also an antacid and helps to neutralize excess stomach acid. As such, many over-the-counter antacids, including Tums and Rolaids, double as calcium supplements. Calcium phosphate has no such antacid properties, so it serves only as a calcium supplement. 00:00.

induced calcium carbonate precipitation (MICP) is a novel approach to improve the stability of the coal ash sediments by using natural, biological processes to cement the particles together. The tendency to capture some heavy metals remaining after coal combustion through co-precipitation is another advantage of using MICP treatment.
