Regenerated backfill soil for building and preparation process of regenerated backfill soil
The invention relates to the technical field of building construction, and particularly discloses regenerated backfill soil for buildings and a preparation process of the regenerated backfill soil. The invention relates to regenerated backfill soil for buildings. The regenerated backfill soil is prepared from the following raw materials in parts by weight: 35-70 parts of regenerated backfill, 40-80 parts of natural gravel, 4-10 parts of fly ash, 15-40 parts of calcium oxide, 2-8 parts of filler fibers and 5-15 parts of composite filler, the preparation process comprises the following steps: S1, weighing the regenerated backfill material, uniformly mixing the regenerated backfill material with the filler fiber, adding the composite filler, uniformly mixing, and drying to obtain a primary mixture; s2, weighing natural gravel, fly ash and calcium oxide, and uniformly mixing and stirring with the primary mixture to obtain a finished product; the backfill soil still has the advantage of being not prone to sinking or settling even under the rainwater washing condition, and can be applied to the field of foundation backfill and pipe ditch backfill.
本申请涉及建筑施工技术领域，具体公开了一种建筑用再生回填土及其制备工艺；一种建筑用再生回填土，包含以下重量份的原料制成：再生回填料35‑70份、天然砂石40‑80份、粉煤灰4‑10份、氧化钙15‑40份、填料纤维2‑8份、复合填料5‑15份；其制备工艺为：S1、称取再生回填料与填料纤维混合均匀后，再添加复合填料混合均匀，干燥后，制得初混料；S2、称取天然砂石、粉煤灰、氧化钙与初混料混合搅拌均匀，制得成品；使回填土即使在雨水冲洗条件下仍具有不易下沉或沉降的优点，能够应用于地基回填和管沟回填领域。
