摘要
通过对水泥、粉煤灰、水玻璃、细砂等材料基本性能的研究 ,并按正交设计法及成型试验确定几种强度和流动性较好的壁后充填注浆浆液试验配合比 ,为工程应用提供依据 ,具有较好的技术和经济效益。
Base on the basic performance research of cement, flyash, water glass, fine sand and other material, orthogonal design method and briquetting test were used to determinate several backfill grout mixture rates with good strength and fluidity, which provide foundations for project application. The backfill material has a good technical and economic benefit.
