Abstract

We propose a new cement recycling process via carbonic acid treatment. The dependencies of the extraction reaction rate on the ratio of waste cement to water, CO₂ pressure, and the particle size of the raw waste cement particles were investigated experimentally with a laboratory-scale setup. Calcium carbonate with about 97 % purity was obtained in the precipitation process. A process simulation was conducted based on the experimental results, and energy consumption and the cost for a model process were estimated. The cost for the production of 1 metric-ton of CaCO₃ for desulfurization of the 500 MW thermal power plant is estimated to be about 120 USD.
