Low-strong-flowability backfill material prepared from construction waste and preparation method of low-strong-flowability backfill material
The invention discloses a low-strong-flowability backfill material prepared from construction waste and a preparation method thereof. The low-strong-flowability backfill material is characterized by comprising water, cement, stone powder, fly ash, recycled fine aggregate and an additive. The construction waste fluidized backfill material provided by the invention is a low-strength cementitious material, has the 28d compressive strength of 2-8MPa, and has the characteristics of self-compaction, environmental protection, economy, adjustable strength and the like.
一种利用建筑垃圾制备的低强流动性回填材料及其制备方法，其特征在于包括由水、水泥、石粉、粉煤灰、再生细骨料和外加剂组成。本发明所提供的建筑垃圾流动化回填材料是一种低强度水泥质材料，28d抗压强度2‑8MPa，具有自密实、环保经济、强度可调节等特点。
