Carbonizable balancing weight with steel slag as main component and preparation method of carbonizable balancing weight
The invention discloses a carbonizable balancing weight with steel slag as a main component and a preparation method of the carbonizable balancing weight. The grouting material comprises the following raw materials: cement, steel slag powder, silica fume, steel slag sand, water and a water reducing agent. According to the invention, the steel slag is adopted as a main component system design, the carbonization activity of the steel slag is fully utilized, the carbonization degree of the sample is improved, and the preparation of the environment-friendly counterweight material with high carbon sequestration amount is realized. The counterweight concrete is prepared by adopting a preset aggregate technology, so that the problem of concrete segregation caused by sedimentation of counterweight components in the counterweight concrete can be effectively prevented, meanwhile, the use volume fraction of the steel slag coarse aggregate can be greatly increased, and the apparent density of the counterweight concrete is ensured; meanwhile, gaps of the steel slag coarse aggregate are filled with the steel slag sand and the steel slag powder, so that the close packing degree of the material is improved, the apparent density of the counterweight concrete is further improved, and the contradiction between counterweight components in the counterweight concrete and sample uniformity is solved.
本发明公开一种以钢渣为主组分的可碳化配重块及其制备方法。其原料包括钢渣粗骨料和灌浆料：其中，灌浆料的原料包括：水泥、钢渣粉、硅灰、钢渣砂、水、减水剂。本发明采用以钢渣为主成分体系设计，充分利用了钢渣的碳化活性，提高试样的碳化程度，实现了高固碳量、环保型配重材料的制备。本发明采用预置骨料技术制备配重混凝土，可有效防止配重混凝土中配重组分的沉降导致混凝土产生离析的问题，同时可大幅增加钢渣粗骨料的使用体积分数，保证配重块混凝土的表观密度；同时，采用钢渣砂和钢渣粉填充钢渣粗骨料的空隙，提高材料的紧密堆积程度，进一步提高配重混凝土的表观密度，解决了重混凝土中配重组分与试样均一性的矛盾。
