Leaching and Detecting Free Magnesium Chloride for Magnesium Oxychloride Cement

Abstract:

The content of free MgCl₂ is one of the key indicators of deliquescence, dehalogenation and efflorescence for Magnesium Oxychloride Cement (MOC). A range of possible techniques for assessing the free MgCl₂ content of MOC have been investigated. The techniques are based on mixing powdered samples with absolute ethyl alcohol and measuring the amount of MgCl₂ passing into solution. The influence of temperature of solvent, extraction time, fineness, agitation and liquid to solid ratio (L/S) are discussed. The results of recovery tests ranged 96.37% or above. The method is successfully applied to leaching and detecting free MgCl₂ in commercial magnesium oxychloride cement fireproof board.
