Glass fiber reinforced cement soil anti-seepage curing material and preparation method thereof
The invention discloses a glass fiber reinforced cement soil anti-seepage curing material. The cement soil anti-seepage curing material consists of the following components in percentage by mass: 8-30% of cement, 4-10% of metakaolin, 3-8% of silica fume, 8-15% of calcium hydroxide, 8-15% of sodium silicate, 1-3% of glass fiber, 15-40% of water and the balance of soil. The cement is used as a cementing material to provide early strength, the metakaolin and the silica fume are used as admixtures, the metakaolin and the silica fume are excited by the calcium hydroxide and the sodium silicate to provide later strength, meanwhile, the metakaolin and the silica fume are filled with cement hydration products and gaps of soil, and the overall strength and the impermeability are improved by adding the glass fibers. The cement soil solidification material with the high anti-seepage coefficient is simple in component and convenient to construct, can be used under the conditions of high water pressure and external seepage, and has a good anti-seepage effect.
本发明公开了一种玻璃纤维增强水泥土防渗固化材料，该水泥土防渗固化材料由以下质量分数的成分组成：水泥8％～30％，偏高岭土4％～10％，硅灰3％～8％，氢氧化钙8％～15％，硅酸钠8％～15％，玻璃纤维1％～3％，水15％～40％，余量为土。本发明采用水泥作为胶凝材料提供前期强度，偏高岭土、硅灰作为外掺料，偏高岭土和硅灰经氢氧化钙及硅酸钠激发提供后期强度，同时偏高岭土和硅灰还将填充水泥水化产物及土的缝隙，通过添加玻璃纤维提高整体强度及抗渗性能，得到防渗系数高的水泥土固化材料，其组分简单、施工方便，可用于高水压及外部渗透情况下，具有很好地防渗效果。
