Light-weight and high-strength foamed magnesium oxysulfate cement and preparation method thereof
The invention discloses light-weight and high-strength foamed magnesium oxysulfate cement and a preparation method thereof. The foamed magnesium oxysulfate cement comprises the following components inparts by weight: 100 parts of light calcined magnesia, 110 parts of a magnesium sulfate solution with a concentration of 15%, 0.5 part of malic acid and 300 parts of magnesium oxysulfate cement foaming agent foam. The 28d dry density of the foamed magnesium oxysulfate cement provided by the invention is 415 kg/m<3>, the compressive strength is 2.83 MPa, the compressive strength is twice higher than that of a common silicate foam concrete sample with the same density, and the foamed magnesium oxysulfate cement has practical application value.
本发明公开了一种质轻、高强的发泡硫氧镁水泥及制备方法，所述发泡硫氧镁水泥包括以下组分及其重量份：100质量份的轻烧氧化镁、110质量份含量为15％的硫酸镁溶液、0.5质量份苹果酸、300体积份的硫氧镁水泥发泡剂泡沫。本发明提供的发泡硫氧镁水泥28d干密度为415kg/m3，抗压强度为2.83MPa，与同密度的普通硅酸盐泡沫混凝土试样抗压强度高出2倍，具有实际应用价值。
