Self-compacting rock-fill concrete for hydraulic structure and preparation method of self-compacting rock-fill concrete
The invention discloses self-compacting rock-fill concrete for a hydraulic structure and a preparation method of the self-compacting rock-fill concrete. The self-compacting rock-fill concrete comprises rock-fill bodies and self-compacting cement grout filled between the rock-fill bodies, the rockfill body comprises a plurality of waste concrete blocks and a plurality of natural block stones, the total volume of the waste concrete blocks accounts for 25%-50% of the total volume of the rockfill body, and the strength grade of the waste concrete blocks is larger than that of the natural block stones. The waste concrete blocks are used for replacing part of natural block stones to form the rock-fill body, the waste concrete regeneration technology is applied to hydraulic structure concrete pouring, the steps of crushing, magnetic separation, skeleton separation, slurry purification and reprocessing of traditional waste concrete regeneration are omitted, the waste concrete regeneration cost and the use threshold are reduced, and the waste concrete regeneration cost is reduced. The popularization of a waste concrete regeneration technology is facilitated. According to the method, the environmental pollution problem caused by treating the waste concrete in a landfill mode is solved while the strength of the self-compacting rock-fill concrete is guaranteed.
本发明公开了一种用于水工建筑物的自密实堆石混凝土及其制备方法，自密实堆石混凝土包括堆石体和填充于堆石体之间的自密实水泥浆液；堆石体包括多块废弃混凝土块和多块天然块石，多块废弃混凝土块的总体积占堆石体总体积的25％‑50％，废弃混凝土块的强度等级大于天然块石的强度等级。本发明利用废弃混凝土块替代部分天然块石构成堆石体，将废弃混凝土再生技术应用到水工建筑物混凝土浇筑中，略去传统废弃混凝土再生“破碎‑磁分选‑骨架分离‑浆液提纯‑再加工”的步骤，降低了废弃混凝土再生花费及使用门槛，有利于废弃混凝土再生技术的推广。本发明在保证自密实堆石混凝土强度的同时解决了采取填埋方式处理废弃混凝土的环境污染问题。
