The invention discloses a high-performance self-compacting cement balancing weight which comprises the following components in parts by weight: 75-100 parts of cement, 10-20 parts of quartz sand, 10-30 parts of fly ash, 1-4 parts of porous ceramsite, 1-2 parts of modified graphene/sodium alginate composite gel fiber, 0.1-0.5 parts of a water reducing agent and 2-6 parts of a defoaming agent. The invention further discloses a preparation method of the high-performance self-compacting cement balancing weight. The prepared cement balancing weight is good in stability, good in compactness, high instrength and low in preparation cost.
本发明公开了一种高性能自密实水泥配重块，以重量份计，包括以下组分：水泥75～100份，石英砂10～20份，粉煤灰10～30份，多孔陶粒1～4份，改性石墨烯/海藻酸钠复合凝胶纤维1～2份，减水剂0.1～0.5份，消泡剂2～6份。本发明还公开该高性能自密实水泥配重块的制备方法。本发明制得的水泥配重块稳定性好，密实性好，强度大，制备成本低。
