Mix proportion design method for preparing low-strength fluidized backfill material from construction waste fine materials
The invention discloses a mix proportion design method for preparing a low-strength fluidized backfill material from construction waste fines. According to the technical scheme, the mix proportion design method is characterized in that the proportional relation among cement, fly ash, the construction waste fines and water in the backfill material prepared from the construction waste fines is determined through three parameters including the lime-sand ratio, the silt-sand ratio and the water-solid ratio. According to the mix proportion design method for preparing the low-strength fluidized backfill material from the construction waste fine materials, the non-renewable fine materials generated in the construction waste production process are utilized, materials such as the cement, the admixture and the water are added, and the backfill material with the strength close to that of backfill soil is prepared; according to the method, the requirement for fluidized filling of the backfill material can be met, self-compaction of the backfill material is achieved, the requirement for the strength of the backfill material of a foundation pit, a groove, a bridge back and the like in engineering can be met, the consistency of the strength of the backfill material and the strength of a surrounding soil body material can be guaranteed, and the characteristic of repeated excavation is achieved.
本发明公开了一种由建筑垃圾细料制备低强度流动化回填材料配合比设计方法，其技术方案要点是：通过灰砂比、粉砂比、水固比三个参数确定建筑垃圾细料制备的回填材料中水泥、粉煤灰、建筑垃圾细料、水之间的比例关系。本发明提供的由建筑垃圾细料制备低强度流动化回填材料配合比设计方法，利用建筑垃圾生产过程中产生的不可再生细料，通过添加水泥、掺合料、水等材料，制备出与回填土强度相接近的回填材料，能够设计出满足回填材料的流动化填筑要求，实现回填材料的自密实，可以满足工程上对于基坑、沟槽、桥背等对回填材料的强度要求，也能够保证回填材料与周围土体材料强度的一致性，并具备可重复开挖性的特点。
