Alternative Binder for Fibercement Building Materials

Abstract:

This paper shows results of some properties of Magnesium oxysulfates (MOS) reinforced by fibers, specially the modulus of rupture (MOR) and durability. As showed by the literature [7], It is known that MOS cement can be formulated by the reaction between magnesium oxide and magnesium sulfate solution and like that of magnesium oxychloride (MOC) has very good binding properties. The resistance of MOS cements to abrasion is about 1.5 times that of Portland cement, but only 50% that of MOC cement. Its compressive and transverse strengths are superior to Portland cement but not as good as MOC cement. In this way, the authors formulated different matrices of MOS cement reinforced by polymeric and cellulose fibers. Also, calcium carbonate was employed. The results showed to be possible the use of MOS fibercements as an alternative for non-asbestos products such as panels and roofing elements besides the effective reduction of CO₂ emission to atmosphere.
