Abstract
A mineral composition is shown which contains a mixed solid phase of synthetic calcium and magnesium carbonates, formed of a crystallized calcic portion and a plate-like crystallized magnesian portion. The crystals of the calcic portion and those of the magnesian portion are aggregated in the form of composite aggregates. These aggregates themselves are at least partly agglomerated in the form of agglomerates. The calcic portion has at least one carbonate such as calcite or the mixtures of calcite and aragonite. The magnesian portion contains hydromagnesite in plate-like form. The aggregates are further formed of a calcic core on which hydromagnesite plates are aggregated. The mineral composition has defined thermal conductivity properties making it suitable for use as a building material.
