Regenerated mixed backfill prepared from engineering wastes and preparation method of regenerated mixed backfill
The invention discloses a regenerated mixed backfill material prepared from engineering wastes. The regenerated mixed backfill material is prepared from the following components in parts by mass: 100 parts of semi-solid slurry, 4-15 parts of a cementing material, 4-35 parts of an admixture, 0.5-4 parts of a crack inhibition type stress shrinking agent and 10-50 parts of water, compared with the prior art, the ratio of the semi-solid slurry in the regenerated mixed backfill material is 50% or above, the use amount of the cementing material does not exceed 13%, the cost of the regenerated mixed backfill material is greatly reduced, and green construction is facilitated.
本发明公开了一种利用工程废弃料制备的再生混合回填料，按照质量份数计算包括以下各组分：半固体泥浆100份、胶凝材料4‑15份、掺合料4‑35份、裂纹抑制型应力收缩剂0.5‑4份、水10‑50份；本发明与现有技术相比，本发明中的再生混合回填料中半固体泥浆的占比在50％以上，胶凝材料的用量不超过13％，大大降低了其成本且有利于绿色施工。
