Calcium carbonate is a commonly occurring mineral calcium carbonate is used as a raw material to produce lime cement and burnt lime Reduction of waste
Calcium carbonate is deposited where evaporation of the water leaves a solution supersaturated with the chemical constituents of (calcium hydroxide), cement and
The pH neutralization process occurs as strong acids react with the calcium carbonate in the limestone through in the waste stream will often come out
A new type of process for producing high purity calcium carbonate from waste cement powder was developed. The process consists of two main reactions; extraction of

The carbonate then quickly reacts with calcium ions released from the cement to rapidly form nano size calcium carbonate (limestone) minerals. The conversion of CO 2 into solid calcium carbonate minerals means that the CO 2 has become permanently bound within the concrete and will never be released back into the atmosphere.
