Stone powder concrete for basement backfilling operation and backfilling method
The invention relates to the technical field of building construction, in particular to a construction technology of basements or narrow spaces, and particularly relates to stone powder concrete for basement backfill operation, which comprises 1800 parts of stone powder per cubic meter, 80 parts of broken stone, 120 parts of cement, 2 parts of admixture and 400 parts of water, and the unit is kg. Generally, the narrow space of the outer wall is backfilled with backfill soil, the compressive strength of the backfill soil is 0.2-0.2 Mpa, but the strength of the backfill soil backfilled with lime powder concrete reaches 8-12 Mpa and is far higher than the design strength.
本发明涉及建筑施工技术领域，尤其涉及地下室或狭小空间的建造技术，具体是一种用于地下室回填作业的石粉混凝土，其配比为每立方米石粉1800份、碎石80份、水泥120份、外加剂2份、水400份，单位kg。一般情况下外墙狭小空间采用回填土进行回填，回填土的抗压强度为0.2‑0.2Mpa，但是本发明采用石灰粉混凝土回填其强度达到8‑12Mpa，远高于设计强度。
