Binary alkali-activated cementing material resistant to sulfate-magnesium salt composite erosion and preparation method of binary alkali-activated cementing material
The invention relates to a binary alkali-activated cementing material resistant to sulfate-magnesium salt composite erosion and a preparation method thereof, the raw materials for preparing the cementing material comprise a composite auxiliary cementing material, a composite activator and mixing water, and the mass ratio of the raw materials is 1: (0.2-0.4): (0.2-0.4). After the binary alkali-activated cementing material prepared by the invention is eroded by a 5% magnesium sulfate solution for 30 days and 60 days, the breaking strength is almost not lost or even is enhanced; after corrosion of a 5% magnesium sulfate solution for 120 days, the breaking strength loss can be controlled to be 15% or below, and the binary alkali-activated cementing material has high sulfate-magnesium salt composite corrosion resistance.
一种抗硫酸盐‑镁盐复合侵蚀的二元体碱激发胶凝材料及制备方法，制备所述凝胶材料的原料包括复合辅助胶凝材料、复合激发剂和拌合水，且各原料的质量比为1:(0.2～0.4):(0.2～0.4)。本发明所制备的二元体碱激发胶凝材料在经过30d和60d的5％硫酸镁溶液侵蚀以后，几乎无抗折强度损失甚至还有所增强；而在经过120d的5％硫酸镁溶液侵蚀以后，抗折强度损失也能控制在15％以下，二元体碱激发胶凝材料具有较强的抗硫酸盐‑镁盐复合侵蚀性能。
