Abstract

This research combines experimental and computational techniques to investigate the Ca(OH)2–H2O system to elucidate the properties of Ca(OH)2 focusing on morphological and dimensional crystal changes.

AFM images taken under controlled conditions highlighted the dissolution mechanism of nano-sized crystals of portlandite. Ab-initio computational data for the adsorption of H2O on portlandite surfaces were developed considering the experimental results.

Results demonstrated the ease of calcium surface ion removal from prismatic faces. These are of great importance for a number of materials used in environmental and industrial applications such as ex-situ CO2 capture and storage, and scrubbing procedures of municipal solid waste incinerators.
