Modified geopolymer foam light soil and preparation method thereof
The invention belongs to the technical field of solid waste resource utilization and engineering materials, and particularly relates to modified geopolymer foam light soil and a preparation method thereof.The foam light soil is prepared from, by weight, 206-319 parts of waste concrete regenerated powder; 33-138 parts of blast furnace slag; 33-35 parts of solid sodium silicate; 9-16 parts of sodium hydroxide; 33 to 65 parts of foam; and 213 to 234 parts of water. The 7d unconfined compressive strength of the modified geopolymer foam light soil prepared by the preparation method can reach 2.456-4.814 MPa, the early strength is increased quickly, the project maintenance period can be greatly shortened, and the construction progress is accelerated. The waste concrete regenerated powder is adopted as a main silicon-aluminum phase raw material of the geopolymer, high-quality utilization of the waste concrete regenerated powder is achieved, and the application prospect is wide.
本发明属于固体废弃物资源化利用和工程材料技术领域，具体涉及一种改性地聚合物泡沫轻质土及其制备方法，所述泡沫轻质土包括以下重量份数的原料：废弃混凝土再生粉体206‑319份；高炉矿渣33‑138份；固体硅酸钠33‑35份；氢氧化钠9‑16份；泡沫33‑65份；水213‑234份。本发明通过制备方法制得的改性地聚合物泡沫轻质土，其7d无侧限抗压强度可达2.456‑4.814MPa，早期强度增长较快，能大大缩短工程养护周期，加快施工进度。本发明采用废弃混凝土再生粉体为地聚合物的主要硅铝相原料，实现了废弃混凝土再生粉体的高质利用，应用前景广阔。
