摘 ? 要：采用化學發泡法制備了堿式硫酸鎂水泥泡沫混凝土（MOSFC），研究了不同摻量的玻璃纖維（GF）和聚丙烯纖維（PP）對MOSFC干密度、導熱系數、孔隙率、體積吸水率、軟化系數和力學性能的影響，并結合XRD、SEM方法分析了其作用機理。結果表明，GF和PP的加入能夠提高MOSFC的強度，且二者的最佳摻量分別為0.5%和1.5%；GF和PP在改善MOSFC力學性能的同時增大了干密度和導熱系數，降低了保溫性能；摻加1.0%的GF能有效改善MOSFC的抗水性能，但PP對MOSFC的抗水性能不利。
Abstract: The chemical foaming method was used to prepare magnesium oxysulfide cement foam concrete(MOSFC), and the effects of glass fiber(GF) and polypropylene fiber(PP) content on the dry density, thermal conductivity, porosity, volumetric water absorption, softening coefficient and mechanical properties of basic magnesium sulfate cement foam concrete were studied, and the mechanism was analyzed by XRD and SEM. The results show that the addition of GF and PP can increase the strength of MOSFC, and the optimal dosage of GF and PP is 0.5% and 1.5%, respectively. The addition of GF and PP can increase the dry density and thermal conductivity while improving the mechanical properties, and the thermal insulation performance decrease. Adding 1%GF can effectively improve the water resistance of MOSFC, but PP is detrimental to the water resistance of MOSFC.
