Solid waste cementing material for cement soil
The invention relates to the technical field of building materials, and discloses a solid waste cementing material for cement soil, which is prepared from the following raw materials in percentage by mass: 10 to 40 percent of cement, 50 to 85 percent of solid waste micro powder and 1 to 30 percent of exciting agent, the specific surface area of the solid waste micro powder is greater than or equal to 600m < 2 >/kg, D90lt; the thickness is 30 microns. According to the solid waste cementing material for the cement soil, through excitation of the exciting agent, the hydration reaction speed is greatly increased, more needle-rod-shaped Aft can be generated, and C-S-H and soil particles are interwoven and filled with the needle-rod-shaped Aft, so that solidified soil is higher in hardening speed, the overall structure is denser, the strength is higher, and the solidification effect is better. Meanwhile, as a large amount of solid waste is used, the cement consumption is reduced, and low-carbon and environment-friendly effects are achieved.
本申请涉及建筑材料技术领域，公开了一种用于水泥土的固废胶凝材料，按照质量百分比计，包括以下原料：水泥10％‑40％、固废微粉50％‑85％、激发剂1％‑30％；固废微粉的比表面积≥600m2/kg，D90<30um。本申请的用于水泥土的固废胶凝材料，通过激发剂激发，水化反应速度大幅度提升，可以产生更多针棒状Aft，其在C‑S‑H和土颗粒之间相互交织填充，使固化土硬化更快，整体结构更密实，强度更高，固化效果更好。同时，由于大量使用固废，减少了水泥用量，绿色低碳环保。
