Magnesium Oxysulfate Fibercement

Abstract:

Recently the use of alternative binder has been verified in several applications like roofing, sheets, panels and refractory. Thus, in this work the authors show results of some properties of Magnesium Oxysulfate Cement reinforced by fibers, specially traction in flexion and durability. MOS cement are formulated and governed by reactions like acid-base between magnesium oxide and magnesium sulfate solution. Some properties as abrasion resistance can be until 1.5 times that of Ordinary Portland Cement. Furthermore its compressive and transverse strengths are also higher than OPC. In the USA and Europe the major use of MOS cement is in the manufacture of lightweight insulating panels. In order to evaluate MOS cement properties, it was analysed two different matrices reinforced by polymeric and cellulose fibers. Calcium carbonate was employed as filler. Tests showed good mechanical behaviour, durability, and the possibility of using MOS fibercements as an alternative for non-asbestos products.
