Low-alkalinity curing agent, vegetation base material for ecological restoration of side slope and preparation method of vegetation base material
The invention relates to the technical field of slope ecological restoration, in particular to a low-alkalinity curing agent, a vegetation substrate for slope ecological restoration and a preparation method of the vegetation substrate. The low-alkalinity curing agent comprises the following components in parts by weight: 50-70 parts of activated aluminum-based mineral powder, 20-30 parts of a gypsum regulator, 10-20 parts of limestone powder and 0.05-0.15 part of a retarder, the low-alkalinity curing agent has the advantages of early strength, low pH value and good durability, the pH value of the low-alkalinity curing agent cured for 7 days is 8.3-9.6, the strength of the low-alkalinity curing agent cured for 28 days is 38.2-45.5 MPa, and the number of freeze-thaw cycles is greater than 120. The vegetation substrate is mainly composed of dry sandy soil, a soil conditioner, a low-alkalinity curing agent, plant fibers, a water-retaining agent, a binder, water and an air entraining agent; the soil has good strength and freeze-thaw resistance, low pH value, high porosity, strong environmental erosion resistance, and significant water and fertilizer retention performance.
本申请涉及边坡生态修复技术领域，尤其涉及一种低碱度固化剂和边坡生态修复的植生基材及其制备方法。所述低碱度固化剂的组分包括：以重量份数计，活化铝基矿物粉：50～70份，石膏调节剂：20～30份，石灰石粉：10～20份和缓凝剂：0.05～0.15份，具有早强、pH值低、耐久性好的优点，低碱度固化剂养护7d的pH为8.3‑9.6，养护28d强度为38.2‑45.5MPa和抗冻融循环次数大于120次。所述植生基材主要由干沙土、土壤调节剂、低碱度固化剂、植物纤维、保水剂、粘结剂、水和引气剂组成；具有良好的强度和抗冻融性能，同时pH值较低、孔隙率高、抗环境侵蚀能力强，保水保肥性能显著。
