Abstrakty

Cement Sorela, znany także jako oksychlorkowy cement magnezowy, był długo stosowany jako specjalny rodzaj cementu do wykonywania podłóg i jako materiał wiążący do płyt wełniano-drzewnych. Znane są także inne liczne zastosowania, w których wykorzystuje się obojętne wypełniacze i pigmenty barwiące, a które obejmują wytwarzanie sztucznych kamieni, podłóg bezspoinowych, sztucznych kości słoniowych (jako kul bilardowych), łączenie szkła z metalem i jako dekoracyjne tynki wewnętrzne i stiuki zewnętrzne zawierające kruszywo skalne. Opisano złożoną chemię procesu hydratacji cementu Sorela obejmującą szereg reakcji rozpuszczania i strącania, powodujących wiązanie, wraz ze specjalnymi odmianami tego cementu do cementowania otworów wiertniczych. Rozważono także możliwość wykonywania pojemników na odpady toksyczne. Wydaje się, że w przyszłości zostaną opracowane normy europejskie na cementy Sorela. Ważne znaczenie ma także określenie bezpiecznego stosowania cementów Sorela.

Sorel cement (also known as magnesium oxychloride cement) has long been used as a special type of cement in flooring and as a binder for wood-wool slabs. There are numerous other applications, which may involve neutral fillers and coloured pigments, including artificial stone manufacture, jointless floors, artificial ivory (as in billiard balls), cementing glass with metal, and in decorative interior plasters and exterior stuccos with embedded stone aggregate. The complex hydration chemistry of Sorel cement for instigating binding by a series of dissolution and precipitation reactions is described along with that of variants of this cement for specialist well cementing downhole. The possibility for encapsulating toxic waste is also considered. European standardisation is likely to arise in the future for Sorel cement. It is important to clarify where Sorel cement can be safely employed and where it is inappropriate to use.
