Anti-freezing corrosion-resistant single-component alkali-activated grouting material and preparation method thereof
The invention discloses an anti-freezing corrosion-resistant single-component alkali-activated grouting material and a preparation method thereof, and belongs to the field of road repair and reinforcement. The anti-freezing corrosion-resistant single-component alkali-activated grouting material is composed of powder and water according to the mass ratio of 100: (33-40), and the powder comprises the following raw materials: an alkali activator, a low-temperature promoting component, mineral powder and metakaolin; the alkaline excitant is a combination of two or more of sodium metasilicate zero hydrate, sodium metasilicate pentahydrate and sodium metasilicate nonahydrate, and the sodium metasilicate zero hydrate accounts for 20-40% of the total mass of the alkaline excitant; the low-temperature promoting component comprises Portland cement, powdery NaOH and potassium carbonate; the mass ratio of the Portland cement to the powdery NaOH to the potassium carbonate is (7.6-25.1): (1.2-3.8): (1.0-1.7). According to the anti-freezing and corrosion-resistant single-component alkali-activated grouting material, the preparation difficulty is simplified according to the construction condition of a grouting site, and the anti-freezing and corrosion-resistant single-component alkali-activated grouting material is suitable for grouting reinforcement in a perpetual frozen soil salinization erosion area and winter construction in a coastal ion erosion area.
本发明公开了一种抗冻耐蚀单组分碱激发注浆材料及其制备方法，属于道路修补加固领域。所述抗冻耐蚀单组分碱激发注浆材料，由粉料与水按质量比100：33～40组成，所述粉料包括以下原料：碱性激发剂、低温促进组分、矿粉、偏高岭土；所述碱性激发剂为零水偏硅酸钠、五水偏硅酸钠与九水偏硅酸钠中的两种或两种以上组合，且零水偏硅酸钠占碱性激发剂总质量的20％～40％；所述低温促进组分包括硅酸盐水泥、粉末状NaOH和碳酸钾；所述硅酸盐水泥、粉末状NaOH、碳酸钾的质量比为7.6～25.1：1.2～3.8：1.0～1.7。本发明所述抗冻耐蚀单组分碱激发注浆材料，依据注浆现场施工条件，简化制备难度，适用于永久冻土盐渍侵蚀区域注浆加固以及沿海离子侵蚀地区冬季施工适用。
